50 degrees
Step-by-step explanation:
180-130=50
Answer:
The answer was already given(50°), but I can explain it further.
Step-by-step explanation:
These are supplementary angles, two angles that, together, make 180 degrees.
We know the angle of one of them, 130°, and in order to find the other one, x, we have to subtract what the entire this equals, 180°:
180° - 130° = x
50° = x
x = 50°

c.)x=2 or x=3
d.) no solution
Answers
Hope this helped! :)
Answer:
x = 2 or x = 3
Step-by-step explanation:
x = 2 + sqrt(x - 2)
x - 2 = sqrt(x - 2) You could divide both sides by sqrt(x - 2)
sqrt(x - 2) = 1 Square both sides
x - 2 = 1 Add 2 to both sides
x = 3
There is a second way.
x - 2 = sqrt(x - 2) Square
x^2 - 4x + 4 = x - 2 Transfer x - 2 to the left
x^2 - 5x + 6 = 0 Factor
(x - 2)(x-3) = 0 Find the roots.
x - 2 = 0
x = 2
x - 3 = 0
x = 3
We have to check both results.
x = 2 + sqrt(x - 2)
2 = 2 + sqrt(2 -2)
2 = 2 + 0
2 = 2 This seems to work.
x = 2 + sqrt(x - 2)
3 = 2 + sqrt(3 - 2)
3 = 2 + sqrt(1)
3 = 2 + 1
3 = 3 And this works.

If 23 cubic meters of water are poured into a conical vessel, it reaches a depth of 12 cm. how much water must be added so that the length reaches 18 cm.?
Answers
Let V be the volume of the conical vessel and r and h be the radius and height of the vessel respectively. Given that: V = (1/3)πr²hLet V' be the volume of the water that is added to the vessel. The volume of the water in the vessel with a depth of 12 cm is given by: V₁ = (1/3)πr₁²h₁where h₁ = 12 cm. We know that 23 cubic meters of water are poured into the vessel, which is equivalent to 23,000 liters or 23,000,000 cubic centimeters.
Thus:23,000,000 = (1/3)πr₁²(12)Simplifying and solving for r₁, we get: r₁ = 210.05 cm Using similar triangles, we know that :r/h = r₁/h₁ where r is the radius of the water surface when the depth is 18 cm. Thus: r/h = 210.05/12Therefore:r = (210.05/12)·18 = 3,152.5/6 ≈ 525.4 cm The new volume of the water with a depth of 18 cm is given by: V₂ = (1/3)πr²h₂where h₂ = 18 cm.
Therefore: V₂ = (1/3)π(525.4)²(18) ≈ 21,154,116.9 cubic centimeters The additional volume of water needed is therefore: V' = V₂ - V₁ = 21,154,116.9 - 23,000,000 ≈ -1,845,883.1 cubic centimeters.

Find the lengths of the curves in y = tan x, -7/3 = x < 0
Answers
The length of the curve y = tan x, -7/3 ≤ x < 0 is approximately 4.481 units.
To calculate the length of the curve, we can use the arc length formula. For a function y = f(x) on the interval [a, b], the arc length is given by the integral:
L = ∫[a,b] √(1 + (f'(x))²) dx,
where f'(x) represents the derivative of f(x) with respect to x.
In this case, the function is y = tan x and the interval is -7/3 ≤ x < 0. To find the derivative, we differentiate y = tan x with respect to x, which gives:
y' = sec² x.
Now we can substitute these values into the arc length formula:
L = ∫[-7/3,0] √(1 + (sec² x)²) dx.
Simplifying the expression under the square root gives:
L = ∫[-7/3,0] √(1 + tan⁴ x) dx.
To evaluate this integral, we can make a substitution. Let u = tan x. Then du = sec² x dx. Using this substitution, the integral becomes:
L = ∫[tan(-7/3),tan(0)] √(1 + u⁴) du.
Now we need to find the limits of integration. Since -7/3 ≤ x < 0, we can evaluate the tangent function at these values to get:
L = ∫[tan(-7/3),0] √(1 + u⁴) du.
Finally, we can use numerical methods or a calculator to evaluate this integral. The result is approximately 4.481 units.

Answers
Using the Bisection method, we need to find solutions accurate to within [tex]10^{-5}[/tex] for the equations [tex]x^{2}[/tex]+ 2x - 3 = 0 in the range -2 < x < 2 and x - [tex]2^{-4}[/tex] = 0 in the range 0 < x < 1.
For the equation [tex]x^{2}[/tex] + 2x - 3 = 0:
We start with an initial interval [-2, 2] and evaluate the function at the midpoint of the interval. If the function value is close to 0, we consider it as the solution. Otherwise, we narrow down the interval by dividing it in half and selecting the subinterval where the function changes sign. This process is repeated until the desired accuracy is achieved (within [tex]10^{-5}[/tex]). The number of iterations required will be recorded.
For the equation x - [tex]2^{-4}[/tex]= 0:
We follow the same steps as above but with the initial interval [0, 1]. Again, we iterate until the desired accuracy is reached and keep track of the number of iterations.
By applying the Bisection method and counting the number of iterations for each equation, we can find solutions accurate to within 10^-5 for both equations and determine the required number of iterations for each case.

Let * be an operation defined on the real numbers R by x*y = x +y - ry. Please answer the following questions and explain your answers. (a) Is * closed on the real numbers? (b) Is * commutative? (c) Is * associative? (d) Does * have an identity element? If so, does every integer have an inverse? (e) Is (R, *) a group?
Answers
(a) No, the operation * is not closed on the real numbers.
To determine closure, we need to check if for any two real numbers x and y, xy is also a real number. However, if we choose r to be any real number other than 1, the result of xy will involve a term (-ry) that may not be a real number, breaking closure.
(b) No, the operation * is not commutative.
Commutativity requires that xy = yx for all real numbers x and y. However, in this case, xy = x + y - ry, while yx = y + x - rx. Since ry and rx are not generally equal, the operation is not commutative.
(c) No, the operation * is not associative.
Associativity requires that (xy)z = x(yz) for all real numbers x, y, and z. However, if we substitute the definition of * into both sides of the equation, we get different expressions that are generally not equal. Therefore, the operation * is not associative.
(d) Yes, the operation * has an identity element.
The identity element e is a real number such that for any real number x, xe = ex = x. In this case, choosing e = 0 satisfies the identity condition, as x0 = x + 0 - r0 = x. However, not every real number has an inverse since there are values of x for which xy = e has no solution, violating the requirement for every element to have an inverse.
(e) No, (R, *) is not a group.
A group requires closure, associativity, an identity element, and every element having an inverse. Since the operation * fails to satisfy closure and does not have inverses for all real numbers, it cannot form a group.

Answers
The bond issue and interest payments are recorded differently based on the market interest rate.
How to find the bond issue and interest payments recorded based on the market interest rate?The recording of bond issue and interest payments depends on the market interest rate. When the market interest rate is equal to the stated rate of 9%, the bonds will issue at their face value of $2,900,000.
On January 1, 2021, the company would debit Cash for $2,900,000 and credit Bonds Payable for $2,900,000 to record the bond issue.
The interest payments on June 30, 2021, and December 31, 2021, would be recorded by debiting Interest Expense for $130,500 ([$2,900,000 * 9%]/2) and crediting Cash for $130,500.
However, when the market interest rate is 10% or 8%, the bonds will issue at a discount or premium, respectively. If the market interest rate is 10%, the bonds will issue at $2,651,193 (rounded).
In this case, the bond issue on January 1, 2021, would be recorded by debiting Cash for $2,651,193 and crediting Discount on Bonds Payable for $248,807 ($2,900,000 - $2,651,193).
The interest payments on June 30, 2021, and December 31, 2021, would be recorded as mentioned earlier.
Conversely, if the market interest rate is 8%, the bonds will issue at $3,186,995 (rounded).
The bond issue on January 1, 2021, would be recorded by debiting Cash for $3,186,995 and crediting Premium on Bonds Payable for $286,995 ($3,186,995 - $2,900,000).
The interest payments on June 30, 2021, and December 31, 2021, would be recorded accordingly.

What is the range and domain of y = (x - 4)(x - 6)? I have already sketched out the graph and parabola.
Answers
Answer: The domain of the function y = (x - 4)(x - 6) is all real numbers, since there are no restrictions on the values that x can take. The range of the function is also all real numbers.
To see why this is the case, we can rewrite the function in standard form by expanding the product: y = (x - 4)(x - 6) = x^2 - 10x + 24. This is a quadratic function with a positive leading coefficient, so its graph is a parabola that opens upwards. The vertex of the parabola is at x = -b/2a = 10/2 = 5, and y = (5 - 4)(5 - 6) = -1. Since the parabola opens upwards, it extends infinitely upwards from its minimum value at the vertex. Therefore, the range of the function is all real numbers greater than or equal to -1.
So, the domain of y = (x - 4)(x - 6) is all real numbers and its range is all real numbers greater than or equal to -1.
Step-by-step explanation:

Let the inverse demand function for the vaccine of the monopolist BoTex be given by:pq=360-2q (p: Price in € ;
q: Quantity in millions of units). The cost function is given by 1000 +q2.
a) Calculate the profit-maximizing quantity of BoTex.
b) Calculate the monopoly price.
c) Calculate the profit.
Answers
The profit-maximizing quantity of Bo Tex is 90 million units.
The monopoly price is 180 million euros.
The profit of Bo Tex is 8400 million euros.
a) Calculation of profit-maximizing quantity of BoTex:
In order to calculate the profit-maximizing quantity of Bo Tex, we have to differentiate the total profit function with respect to q and equate the result to zero.
Total profit (Π) = Total revenue (TR) – Total cost (TC)TR = p.
q = (360 - 2q)q = 360q - 2q2TC = 1000 + q2Π = TR - TC
Differentiating Π w.r.t. q: {d \Pi}{dq} = 360 - 4q
Equating it to zero, we get:
360 - 4q = 0q = 90 million units
Therefore, the profit-maximizing quantity of Bo Tex is 90 million units.
b) Calculation of monopoly price:
To calculate the monopoly price, we need to substitute the quantity obtained in part (a) into the inverse demand function:
pq = 360 - 2q = 360 - 2(90) = 180 million euro
Therefore, the monopoly price is 180 million euros.
c) Calculation of profit:
We have to substitute the value of quantity (90 million units) and price (180 million euros) into the total revenue and total cost functions.
Total revenue (TR) = p.q = 180 × 90 = 16,200 million euro
Total cost (TC) = 1000 + q2 = 1000 + 902 = 8200 million euro
Profit (Π) = TR - TC = 16,200 - 8200 = 8400 million euro
Therefore, the profit of Bo Tex is 8400 million euros.

Answers
The Laplace transform of [tex][f(t) = \sin{\sqrt{24}} + te^{-t}\sin{t} \implies L{f(t)} = \frac{\sqrt{24}}{s^2 + 24} + \frac{1}{(s + 1)^2 + 1}][/tex] . However, F(s) = 1 + 1 cannot be the Laplace transform of any valid function f(t) because it does not satisfy the properties and rules of Laplace transforms.
To determine the Laplace transform of the function [tex]\[f(t) = \sin{\sqrt{24}} + te^{-t}\sin{t}\][/tex], we need to apply the properties and formulas of Laplace transforms.
1. Laplace Transform of sin(√24):
The Laplace transform of sin(at) is given by [tex]\[F(s) = \frac{a}{s^2 + a^2}\][/tex]. In this case, a = √24.
So, the Laplace transform of [tex]\[\sin{\sqrt{24}} \implies F(s) = \frac{\sqrt{24}}{s^2 + 24}\][/tex].
2. Laplace Transform of [tex]\[te^{-t}\sin{t}\][/tex]:
To find the Laplace transform of this term, we can use the product rule and the Laplace transform of each component.
The Laplace transform of t is given by [tex]\[F(s) = \frac{1}{s^2}\][/tex], and the Laplace transform of e^(-t)sin(t) can be found using the table of Laplace transforms.
Using the table, the Laplace transform of [tex]\begin{equation}\mathcal{L}(e^{-t}\sin(t)) = \frac{1}{(s + 1)^2 + 1}[/tex].
3. Adding the Laplace transforms:
Since the Laplace transform is a linear operator, we can add the individual Laplace transforms of [tex]sin(\sqrt{24})[/tex] and [tex]te^{-t}\sin(t)[/tex] to obtain the Laplace transform of the whole function f(t).
Therefore, [tex]L\{f(t)\} = \frac{\sqrt{24}}{s^2 + 24} + \frac{1}{(s + 1)^2} + 1[/tex]
Now, to address the second part of the question:
Is it possible for F(s) = 1 + 1 to be the Laplace transform of some function f(t)?
No, it is not possible for F(s) = 1 + 1 to be the Laplace transform of a valid function f(t). The Laplace transform is a mathematical operation that converts a function of time (f(t)) into a function of the complex variable s (F(s)). The Laplace transform must follow specific properties and rules, and it is not possible for F(s) = 1 + 1 to satisfy these properties and correspond to a valid function f(t).
