If the relationship between demand and supply is given then the exchange rate is a) Under a clean float, the exchange rate E depends on demand and supply. b) Fixing the rate requires central bank intervention.
a) Under a clean float, the exchange rate (E) between the Olympios Dollar and the Terranian Credit is determined by the demand (D) and supply (S) functions. The exchange rate is given by E = 8.75 - 0.03D, where D represents the index of demand for the Olympios Dollar, and S represents the index of supply. By plugging in the values of D and S, we can calculate the prevailing exchange rate.
ii) The exchange rate under a clean float impacts the balance of payments of Olympios. If the exchange rate increases, it makes Olympios Dollar more expensive relative to the Terranian Credit, potentially affecting exports and imports and thus influencing the trade balance and overall balance of payments.b) Fixing the exchange rate at E = 1.5 Terranian Credits per Olympios Dollar requires intervention from the central bank. In the short run, the central bank would need to buy or sell foreign currency to maintain the fixed rate, impacting its foreign exchange reserves. The balance of payments would depend on the central bank's actions to maintain the fixed rate.
ii) To maintain the fixed exchange rate in the long run, the government may need to implement various measures such as implementing monetary policies, controlling inflation, and ensuring a favorable economic environment. The government may also need to monitor the balance of payments and make adjustments if necessary to sustain the fixed exchange rate over an extended period.To learn more about “exchange rate ” refer to the https://brainly.com/question/10187894

The mass m(t), in grams, of a tumort months after it begins to grow is tet given by m(t) = Find the average rate of change, in grams per 60 month, during the sixth month of growth.
The average rate of change in grams per month of the tumor in the sixth month is about 27.975 grams per month
What is the average rate of change of a function?The average rate of a function on an interval is the ratio of the change in the value of the function to the change in the value of the input variable.
The possible function for the mass of the tumor, obtained from a similar question on the internet is; m(t) = (t·e^t)/60
Therefore, the average rate of change of the mass of the tumor in the during the sixth month of growth, can be obtained from the change in the mass from t = 5 to t = 6 as follows;
m(t) = (t·e^t)/60
m(5) = (5 × e^5)/60
m(6) = (6 × e^6)/60
The change in the mass of the tumor = m(6) - m(5) = (6 × e^6)/60 - (5 × e^5)/60
The change in the time = 6 - 5 = 1 month
The average rate of the mass of the tumor in the sixth month is therefore;

What is the standard form equation of an ellipse that has vertices (-2, 14) and (-2,-12) and foci (-2,9) and (-2,-7)?
The standard form equation of an ellipse with vertices (-2, 14) and (-2, -12) and foci (-2, 9) and (-2, -7) can be expressed as (x + 2)²/16 + (y - 1)²/225 = 1.
To determine the standard form equation of the ellipse, we need to find the center, major axis length, and minor axis length. The center of the ellipse can be determined by taking the average of the vertices, which gives us (-2, (14 - 12)/2) = (-2, 1).
Next, we calculate the distances from the center to the vertices and the foci. The distance from the center to the vertices is the major axis length, and the distance from the center to the foci is related to the eccentricity of the ellipse.
The major axis length is obtained as the absolute difference between the y-coordinates of the vertices: 14 - (-12) = 26.
The distance from the center to the foci is found as the absolute difference between the y-coordinates of the foci: 9 - (-7) = 16.
Since the foci are located on the y-axis and the center is at (-2, 1), we can write the equation in the standard form:
(x + 2)²/16 + (y - 1)²/225 = 1.
This equation represents the ellipse with the given vertices and foci.

Find an equation of the sphere with center (-3, 2, 6) and radius 5. What is the intersection of this sphere with the yz-plane? x = 0
The intersection of the sphere with the yz-plane is a circle centered at (2, 6) with a radius of 5.
The equation of a sphere with center (h, k, l) and radius r is given by (x - h)^2 + (y - k)^2 + (z - l)^2 = r^2. In this case, the center is (-3, 2, 6) and the radius is 5, so the equation of the sphere is (x + 3)^2 + (y - 2)^2 + (z - 6)^2 = 25.
To find the intersection of the sphere with the yz-plane (x = 0), we substitute x = 0 into the equation of the sphere. This gives (0 + 3)^2 + (y - 2)^2 + (z - 6)^2 = 25, which simplifies to 6^2 + (y - 2)^2 + (z - 6)^2 = 25. This equation represents a circle in the yz-plane centered at (2, 6) with a radius of 5.

There is no solution to the given system of equations hence there is no system of equations that must be solved to find x.
The given matrix is a regular stochastic matrix. A regular stochastic matrix is one that has all its entries in the range (0, 1), and its row and column sums are equal to one. To obtain the stable distribution for a regular stochastic matrix, the following steps should be followed:
Let [x y] be the stable distribution
Solve for x and y from the following system of equations:
0.6x + 0.1y = x0.4x + 0.9y = yx + y = 1
Multiplying the third equation by 10 gives 10x + 10y = 10 ----(1)
Multiplying the first equation by 10 gives 6x + y = 10x = (10 - y)/4 ----(2)
Substituting x from equation (2) into equation (1) gives:
60 - 5y = 10 - y54 = 4y y = 54/4 = 13.5
Substituting the value of y in equation (2) gives: x = (10 - y)/4 = (10 - 13.5)/4 = -1.125

The effect of recording the retirement is a $6,250 loss. Option C is correct.
A $500,000 bond is retired at 101% when the unamortized premium is $4,500. The effect of recording the retirement is a $6,250 loss.
How to calculate the loss: The bond is retired at 101% of its face value.
Therefore, the selling price is:Face value = $500,000Selling price = 101% of face value = 1.01 * $500,000 = $505,000The unamortized premium is $4,500.
Therefore, the book value of the bond at the time of retirement is:
Face value + Unamortized premium = $500,000 + $4,500 = $504,500.
Since the selling price is greater than the book value, there is a gain.
The gain is calculated as the difference between the selling price and the book value.
Gain = Selling price - Book value= $505,000 - $504,500 = $500

Let f: (1, infinity) -> reals be defined by f(x) = ln(x). Determine whether f is injective/surjective/bijective.
Find a bijection from the integers to the even integers. If f: Z -> 2Z is defined by f(x) = 2x, find the inverse of f. Let g: R -> R be defined by g(x) = 2x+5 . Prove g bijective and find the inverse of g.
Let f: R -> R with f(x) = x^2, g: R -> R with g(x) = 2x+1, h: [0, infinity) -> reals with h(x) = sqrt(x).
Find the compositions of: f and g, g and f, f and h, h and f.
f(x) = ln(x) is injective but not surjective, therefore not bijective.
A bijection from Z to 2Z is f(x) = 2x, with inverse g(x) = x/2.
g(x) = 2x + 5 is bijective, with inverse g^(-1)(x) = (x - 5)/2.
Compositions: (f ∘ g)(x) = ln(2x + 5), (g ∘ f)(x) = 2ln(x) + 5, (f ∘ h)(x) = ln(sqrt(x)), (h ∘ f)(x) = |x|.
To determine whether a function is injective, surjective, or bijective, we need to analyze its properties:
Function f(x) = ln(x), defined on the interval (1, infinity):
Injective: For f to be injective, different inputs should map to different outputs. In this case, ln(x) is injective because different values of x will result in different values of ln(x).
Surjective: For f to be surjective, every element in the codomain should have a corresponding element in the domain. However, ln(x) is not surjective because its range is the set of all real numbers.
Bijective: Since ln(x) is not surjective, it cannot be bijective.
Bijection from integers to even integers:
A bijection from the set of integers (Z) to the set of even integers (2Z) can be defined as f(x) = 2x, where x is an integer. This function doubles every integer, mapping it to the corresponding even integer. It is both injective and surjective, making it a bijection.
Inverse of f(x) = 2x (defined on Z):
The inverse of f(x) = 2x is given by g(x) = x/2. It takes an even integer and divides it by 2, resulting in the corresponding integer.
Function g(x) = 2x + 5, defined on the real numbers (R):
Injective: g(x) = 2x + 5 is injective because different values of x will produce different values of g(x).
Surjective: For g to be surjective, every real number should have a corresponding element in the domain. Since g(x) can take any real number as its input, it covers the entire range of real numbers and is surjective.
Bijective: Since g(x) is both injective and surjective, it is bijective.
The inverse of g(x) = 2x + 5 can be found by solving the equation y = 2x + 5 for x:
x = (y - 5)/2
The inverse function is given by g^(-1)(x) = (x - 5)/2.
Compositions:
f and g: (f ∘ g)(x) = f(g(x)) = f(2x + 5) = ln(2x + 5)
g and f: (g ∘ f)(x) = g(f(x)) = g(ln(x)) = 2ln(x) + 5
f and h: (f ∘ h)(x) = f(h(x)) = f(sqrt(x)) = ln(sqrt(x))

Let v, w∈Rn. If |‖v‖=‖w‖, show that v+w and v−w are orthogonal (perpendicular). Solution: Let's assume that |‖v‖=‖w‖. Then it implies that ‖v‖2=‖w‖2... (1)Now, let's consider (v+w).(v-w) =(v.v)+(v.-w)+(w.v)+(w.-w)(dot product formula). The cross terms will be zero as we consider vectors v and w to be orthogonal. So, (v.w)+(w.v). Now, we know that, v.w = |v||w|cosθw.v = |v||w|cosθ(w -ve angle will be taken as w.v will give negative value).
Therefore, v.w + w.v = |v||w|cosθ +|v||w|cosθ= 2|v||w|cosθ. From (1) above, we can say that, |v|=|w|. So, v.w + w.v = 2|v||w|cosθ = 2|v|2cosθ = 2‖v‖2cosθ=(v+w).(v-w) = 2‖v‖2cosθ. Here, we have two vectors (v+w) and (v-w), which makes an angle of θ with each other, from the above step it is evident that the dot product of these vectors is zero.

The equation 4x^2 - 30 = 34 can be solved to find the values of x. In this case, there are two solutions: x = -2 and x = 2.
To solve the equation 4x^2 - 30 = 34, we need to isolate the variable x.
First, we bring the constant terms to one side of the equation:
4x^2 - 30 - 34 = 0
Simplifying, we have:
4x^2 - 64 = 0
Next, we factor out the common factor:
4(x^2 - 16) = 0
Now, we can solve for x by setting each factor equal to zero:
x^2 - 16 = 0
Using the difference of squares formula, we can factor the equation further:
(x - 4)(x + 4) = 0
Setting each factor equal to zero, we have two equations:
x - 4 = 0 or x + 4 = 0
Solving for x in each equation, we find:
x = 4 or x = -4

Which of the two margins of error will lead to wider interval? The margin of error with 9580 confidence The margin of error with 9990 confidence_
The margin of error with 9990 confidence will lead to the wider interval
The margin of error is a close estimate of the confidence interval at a certain level of probability. It is described as a very small percentage that is built in for errors. The degree of confidence denotes the likelihood that the population parameter in the interval estimation is accurate. A higher degree of assurance or accuracy in an estimate is implied by a higher confidence level.
The range of values that the genuine population parameter is expected to fall within is bigger when the interval is wider. This wider range indicates the higher degree of confidence that is required and provides for a larger estimating error. In contrast to the margin of error with a 95% confidence level, the margin of error with a 99% confidence level (9990 confidence) will often result in a broader interval as compared to 9580.

To factor the GCF, we need to identify the common factors present in all the terms. In this case, the common factors among the terms are 3, x, and y. By factoring out the GCF, we can rewrite the expression as 3xy multiplied by the remaining factors.
The GCF, 3xy, is then distributed to each term within the parentheses. This process leaves us with the expression (4x^2 - 2xy - 3y^2) within the parentheses. By factoring out the GCF, we have effectively extracted the common factors, leaving behind the remaining factors that differ from term to term.

Now, we have four smaller squares and five selected points.
By the Pigeonhole Principle, if we distribute the five points into the four squares, at least two points must be in the same smaller square.
Since the side length of each smaller square is √2/2 unit, the maximum distance between any two points within the same smaller square is √2/2 units.

A meeting takes place between a diplomat and fourteen government officials. However, four of the officials are actually spies. If the diplomat gives secret information to one of the attendees at random, what is the probability that secret information was only given to the real officials (no spies )?
The probability that secret information was only given to the real officials (no spies) can be calculated by dividing the number of favorable outcomes by the total number of possible outcomes (all attendees).
In this scenario, there are 14 attendees in total, out of which 4 are spies. Therefore, the number of real officials is 14 - 4 = 10. The diplomat can choose any one of the 10 real officials to give the secret information to. So, the probability is given by the ratio of the number of favorable outcomes (10) to the total number of possible outcomes (14): Probability = 10 / 14 = 5 / 7 ≈ 0.714. Therefore, the probability that secret information was only given to the real officials is approximately 0.714 or 71.4%.

The provided dataset includes information on the median age, median income, average bank balance, and median years of education for different zip codes.
To analyze the distribution of the average account balance, a histogram can be created using the provided data. The histogram provides a visual representation of the frequency or count of different values or ranges of the average account balance. Descriptive statistics such as the mean, median, and standard deviation can be computed to describe the center and spread of the distribution. The mean represents the average balance, the median indicates the middle value, and the standard deviation measures the dispersion or spread of the data points around the mean.
Scatterplots can be generated to visualize the associations between bank balance and the other variables: age, education, and income. Scatterplots help identify any patterns or relationships between variables. By plotting bank balance on the y-axis and each of the other variables on the x-axis, we can observe how the bank balance varies with changes in each independent variable. Additionally, the scatterplots can provide insights into whether the associations appear to be linear, indicating a potentially strong relationship between the variables.
Correlation values can be computed to quantify the strength and direction of the associations between bank balance and the other variables. The correlation coefficient ranges from -1 to 1, with values closer to -1 or 1 indicating a strong negative or positive association, respectively. A correlation value of 0 suggests no linear relationship between the variables. By calculating the correlation between bank balance and each independent variable, we can determine which pairs of variables are strongly associated.
In the regression analysis, the independent variables are age, education, and income, while the dependent variable is the average account balance. A regression model can be fitted using these variables to predict the balance. The model parameters, such as the coefficients and their significance, can be analyzed. By conducting t-tests on the parameters using a significance level (alpha) of 0.05, we can determine which predictors have a significant effect on the balance.
If any predictors are found to be non-significant, they can be removed from the model, and a new regression model can be fitted. The expression of the newly fitted regression model can be written based on the remaining significant predictors.
The R2 coefficient measures the proportion of the variance in the dependent variable (balance) that can be explained by the independent variables (age, education, income). It ranges from 0 to 1, with a higher value indicating a better fit of the model. The R2 coefficient can be interpreted as the percentage of the variation in the average account balance that can be accounted for by age, education, and income.
Using the final model, the predicted average balance for a specific zip code area can be computed by plugging in the median values of age, education, and income for that area. By comparing the predicted average balance to the observed average balance, the model prediction error can be calculated.

1. Springtime Fabrics finds its cost function as, TC= 10Q²+10Q+10 Its demand function is P= 190 - 5Q a) Derive the MC and the AC. b) Find where the AC is minimized. c) What is the minimum AC? d) What is the profit maximizing level of output (Q)?
a) AC = 10Q² + 10Q + 10 / Q
b) Q = 2 is the point where AC is minimized.
c) AC = 50
d) The profit maximizing level of output is Q = 6.
Given the following cost function, TC = 10Q² + 10Q + 10And the demand function is, P = 190 - 5Q
a) MC stands for Marginal cost which is the cost of producing one more unit of the output.
To find the MC, we need to differentiate the cost function with respect to Q, i.e., TC = 10Q² + 10Q + 10dTC/dQ = 20Q + 10MC = 20Q + 10
Also, AC stands for Average cost which is the cost per unit of output. AC is calculated as follows:
AC = TC / Q
Substituting the value of TC in terms of Q, we get:
AC = 10Q² + 10Q + 10 / Q
b) To find where the AC is minimized, we need to differentiate the AC function with respect to Q and equate it to zero. d(AC)/dQ = 20Q - 10Q² / Q² = 0
Solving for Q, we get:
Q = 0 or 2Since the firm produces output, Q = 0 is not the answer.
Hence, Q = 2 is the point where AC is minimized.
c) Substituting Q = 2 in the AC function, we get:
AC = 10(2)² + 10(2) + 10 / 2 = 50
d) Profit maximizing level of output is where MR = MC. And, MR is calculated as follows:
MR = dTR / dQ = P * dQ / dQ = P
Substituting the value of P in terms of Q, we get:
MR = 190 - 5Q
Profit maximizing level of output is where MR = MC.190 - 5Q = 20Q + 10
Solving for Q, we get: Q = 6
The profit maximizing level of output is Q = 6.

In a study by Gallup, data was collected on Age of participants and their Opinion on the legality of abortion. The data is summarized in the contingency table below. Age and Opinion on legality of Abortion .Does the Opinion depend on Age? Do a hypothesis test at 5% significance level to conclude if there is any association between Age of participants and their Opinion on the legality of abortion.
To determine if there is any association between Age and Opinion on the legality of abortion, a hypothesis test can be conducted at a 5% significance level. The goal is to assess whether the Opinion depends on Age.
In order to test the association between Age and Opinion on the legality of abortion, a chi-square test of independence can be performed. This test helps determine if there is a significant relationship between two categorical variables.
The null hypothesis (H₀) assumes that there is no association between Age and Opinion, meaning the variables are independent. The alternative hypothesis (H₁) assumes that there is an association between the variables.
The chi-square test calculates the expected frequencies under the assumption of independence and compares them to the observed frequencies. If the calculated chi-square statistic exceeds the critical value at the chosen significance level (5% in this case), we reject the null hypothesis and conclude that there is evidence of an association between Age and Opinion.
By performing the chi-square test and comparing the calculated chi-square statistic to the critical value, we can make a conclusion about whether the Opinion on the legality of abortion depends on Age.

One card is drawn from a standard 52-card deck. Determine the probability that the card selected is not a 5.
There is a 92.3% chance that the card drawn from a standard 52-card deck is not a 5.
To find the probability that the card selected is not a 5, we need to determine the number of cards that are not 5 and divide it by the total number of cards in the deck.
In a standard 52-card deck, there are four 5s (one for each suit: hearts, diamonds, clubs, and spades).
Therefore, the number of cards that are not 5 is 52 - 4 = 48.
The total number of cards in the deck is 52.
So, the probability of selecting a card that is not a 5 is given by:
Probability = Number of favorable outcomes / Total number of outcomes
= Number of cards that are not 5 / Total number of cards in the deck
= 48 / 52
Simplifying this fraction, we get:
Probability = 12 / 13
Therefore, the probability that the card selected is not a 5 is 12/13 or approximately 0.923.
In summary, there is a 92.3% chance that the card drawn from a standard 52-card deck is not a 5.

The rate of change of demand is -221. This indicates that for every $1 increase in price, the demand for the product will decrease by 221 units.
The demand function is provided as follows: x = 800 − p −4pp + 3, p = $5The problem statement requires us to use the demand function to find the rate of change in demand (x) for a given price (p) and round the answer to two decimal places.
As per the problem statement, the price is given as $5. Therefore, we substitute the value of p in the demand function: x = 800 − (5) −4(5)(5) + 3x = 787We now differentiate the demand function to find the rate of change in demand.
Since the value of x can be a function of time, the differentiation results in the rate of change of x with respect to time. However, as per the problem statement, we are interested in the rate of change of x with respect to p.
Therefore, we use the chain rule of differentiation as follows: dx/dp = dx/dx * dx/dp Where dx/dx = 1, and dx/dp is the rate of change of x with respect to p.
dx/dp = 1 * d/dp [800 - p - 4p(p) + 3]dx/dp = -1 - 4p (1+2p)dx/dp = -1 - 4p - 8p²The rate of change of demand for p = $5 is given as follows: dx/dp = -1 - 4(5) - 8(5)²dx/dp = -1 - 20 - 200dx/dp = -221Therefore, the rate of change of demand is -221.

Find the general solution of the following differential equation 2xdx – 2ydy = x^2ydy – 2xy^2dx.
The general solution of the following differential equation 2xdx – 2ydy = x^2ydy – 2xy^2dx is x² + C = 0
Given differential equation is: 2xdx – 2ydy = x²ydy – 2xy²dx
Now, let us write this equation in the form of an exact differential equation.
To do this, we will use the following criteria:
For the given equation Mdx + Ndy to be exact differential equation, we have to check the following:
∂M/∂y = ∂N/∂x …..(1)
On comparing the given differential equation with the exact differential equation, we have;
M = 2x and N = -2y + x²y
If we calculate ∂M/∂y and ∂N/∂x, we have;∂M/∂y = 0 and ∂N/∂x = 2xy
Therefore, as per criteria (1), we have the given differential equation as an exact differential equation.
Now, to solve the given differential equation, we will find a function F(x,y) such that,
F(x,y) = ∫(2x)dx = x² + C1 (where C1 is a constant of integration)
Now, to find the value of C1, we will differentiate F(x,y) with respect to y and equate it to N.
∂F/∂y = (-2y + x²) ∴ ∂F/∂y = N = -2y + x²y
On equating the above two expressions, we get;(-2y + x²) = -2y + x²y
∴ -2y + x² - 2y + x²y = 0 ∴ x²y - 4y = 0 ∴ y(x² - 4) = 0 ∴ y = 0 or x² - 4 = 0
Therefore, y = 0 is a trivial solution, while x² - 4 = 0 gives x = ± 2
Therefore, the general solution of the given differential equation is;
F(x,y) = x² + C1 = C2 (where C2 is a constant of integration)
Hence, we have the general solution of the given differential equation as x² + C = 0

A² - 2A + 5I = 0, where A is the matrix representing the system.
Let λ be the eigenvalue and v be the corresponding eigenvector.
From the given equation:
(A - 5I)(A + I) = 0
This implies that the eigenvalues are 5 and -1.
For the eigenvalue λ = 5:
(A - 5I)v = 0
This gives us the eigenvector v₁.
For the eigenvalue λ = -1:
(A + I)v = 0
This gives us the eigenvector v₂.
Now, let's solve for the eigenvectors:
For λ = 5:
(A - 5I)v₁ = 0
Substituting A = 2A² gives us:
2A²v₁ - 10v₁ = 0
2(A² - 5)v₁ = 0
Since A² - 5I = 0, we have:
2(0)v₁ = 0
This implies that v₁ can be any non-zero vector.
For λ = -1:
(A + I)v₂ = 0
Substituting A = 2A² gives us:
2A²v₂ + 2v₂ = 0
2(A² + 1)v₂ = 0
Since A² + I = 0, we have:
2(0)v₂ = 0
Again, v₂ can be any non-zero vector.
So, we have found two linearly independent eigenvectors, v₁ and v₂.
The general solution to the system can be written as:
[tex]X(t) = c_1 * v_1 * e^{\lambda_1 * t} + c_2 * v_2 * e^{\lambda_2 * t}[/tex]
where c₁ and c₂ are arbitrary constants, v₁ and v₂ are the eigenvectors, and λ₁ and λ₂ are the corresponding eigenvalues.
Now, let's move on to the second part of the question.
Given the system of equations:
dx/dt = -2x
dy/dt = z
dz/dt = -1
We are told that the system has a repeated eigenvalue of -1 and f = -1 is one solution.
To find the second linearly independent solution, we need to find the corresponding eigenvector.
For λ = -1:
(A + I)v = 0
Substituting the given system of equations, we have:
[[0 -2 0], [0 0 1], [0 0 0]]v = 0
Solving this system of equations, we get:
-2y = 0
z = 0
Therefore, we can choose the eigenvector v = [1, 0, 0].
This second linearly independent solution corresponds to the repeated eigenvalue of -1.

Find the potential function f for the field F.
F = 2xe x2+y2 i + 2ye x2+y2 j
To find the potential function f for the given vector field F = 2xe^(x^2+y^2)i + 2ye^(x^2+y^2)j, we need to find a function whose gradient matches the components of F.
Let's assume that f(x, y) is the potential function we're looking for. The gradient of f is given by ∇f = (∂f/∂x)i + (∂f/∂y)j.
To find f, we need to equate the components of F to the corresponding partial derivatives of f:
2xe^(x^2+y^2) = ∂f/∂x
2ye^(x^2+y^2) = ∂f/∂y
We can integrate the first equation with respect to x to obtain f:
∫2xe^(x^2+y^2) dx = f(x, y) + g(y),
where g(y) is the constant of integration with respect to x. Taking the partial derivative of f(x, y) + g(y) with respect to y, we can match it with the second equation:
∂f/∂y + ∂g/∂y = 2ye^(x^2+y^2).
Since the second equation only depends on y, we can conclude that ∂g/∂y = 2ye^(x^2+y^2). Integrating this equation with respect to y, we obtain g(y) = ∫2ye^(x^2+y^2) dy.
Finally, combining f(x, y) + g(y) = ∫2xe^(x^2+y^2) dx + ∫2ye^(x^2+y^2) dy, we find the potential function f for the given vector field F:
f(x, y) = ∫2xe^(x^2+y^2) dx + ∫2ye^(x^2+y^2) dy.
Please note that finding the exact form of f may require further integration calculations.
