Answers

Answer 1

The first 4-terms of sequence {aₙ} defined by recurrence-relation : aₙ₊₁ = 2aₙ²-1;  a₁ = 0 are 0, -1, 1 and 1.

To find the first four terms of the sequence {aₙ} defined by the recurrence relation aₙ₊₁ = 2aₙ² - 1, with the initial-condition a₁ = 0, we apply the recurrence relation,

Starting with a₁ = 0, we can find the subsequent terms as follows:

⇒ a₂ = 2a₁² - 1 = 2(0)² - 1 = -1

⇒ a₃ = 2a₂² - 1 = 2(-1)² - 1 = 1

⇒ a₄ = 2a₃² - 1 = 2(1)² - 1 = 1

Therefore, the first four terms of the sequence are : a₁ = 0, a₂ = -1, a₃ = 1

and a₄ = 1.

a general solution of the differential equation x′(t)=ax is given by x(t)=c1x1(t) c2x2(t), where a matrix A = [0 -1; 1 0]?

Answers

The general solution of the differential equation x'(t) = Ax(t), where A is the matrix [0 -1; 1 0], is x(t) = [(c₁² - c₂² + 2ic₁c₂)[tex]e^{(it)[/tex] + (2c₁c₂ - c₁² + c₂²)[tex]e^{(it)[/tex]][1, i].

To solve the differential equation x'(t) = Ax(t), where A is the given matrix [0 -1; 1 0], we can use the method of finding the eigenvalues and eigenvectors.

Step 1: Find the eigenvalues λ of the matrix A by solving the characteristic equation |A - λI| = 0.

The characteristic equation for A is:

|0-λ -1| = 0

|1 0-λ|

Expanding the determinant gives:

(-λ)(-λ) - (-1)(1) = 0

λ² + 1 = 0

Solving the equation, we get two eigenvalues: λ₁ = i and λ₂ = -i.

Step 2: Find the eigenvectors corresponding to each eigenvalue.

For λ₁ = i:

(A - λ₁I)u₁ = 0

|0- i -1| |x₁| = |0|

|1 0- i| |x₂| |0|

Simplifying the equation gives:

-ix₁ - x₂ = 0

x₁ - ix₂ = 0

Solving this system of equations, we get the eigenvector u₁ = [1, i].

For λ₂ = -i:

(A - λ₂I)u₂ = 0

|0+i -1| |x₁| = |0|

|1 0+i| |x₂| |0|

Simplifying the equation gives:

ix₁ - x₂ = 0

x₁ + ix₂ = 0

Solving this system of equations, we get the eigenvector u₂ = [1, -i].

Step 3: Write the general solution as x(t) = c₁x₁(t) + c₂x₂(t), where c₁ and c₂ are constants.

The general solution to the differential equation x'(t) = Ax(t) is:

x(t) = c₁[1, i][tex]e^{(i\lambda_1 t)[/tex] + c₂[1, -i][tex]e^{(i\lambda_2 t)[/tex]

= c₁[1, i][tex]e^{(it)[/tex] + c₂[1, -i][tex]e^{(it)[/tex]

Expanding and simplifying the solution:

x₁(t) = c₁[tex]e^{(it)[/tex] + c₂[tex]e^{(it)[/tex]

x₂(t) = ic₁[tex]e^{(it)[/tex] - ic₂[tex]e^{(it)[/tex]

Therefore, the general solution is:

x(t) = c₁[c₁[tex]e^{(it)[/tex] + c₂[tex]e^{(it)[/tex]][1, i] + c₂[ic₁[tex]e^{(it)[/tex] - ic₂[tex]e^{(it)[/tex]][1, -i]

= (c₁c₁[tex]e^{(it)[/tex] + c₁c₂[tex]e^{(it)[/tex] + ic₁c₁[tex]e^{(it)[/tex] - ic₁c₂[tex]e^{(it)[/tex])[1, i] + (ic₁c₁[tex]e^{(it)[/tex] - ic₁c₂[tex]e^{(it)[/tex] - c₂c₁[tex]e^{(it)[/tex] - c₂c₂[tex]e^{(it)[/tex])[1, -i]

Consider the function f(3) = 1/cose. Estimate the condition number for the problem of evaluating this function near the point 1.5708. Calculate the input and output relative errors whe

Answers

The condition number for the problem of evaluating the function f(x) = 1/cos(x) near the point x = 1.5708 is approximately 10 raised to power 16

This means that a small change in the input x can cause a large change in the output f(x).

The condition number of a function is a measure of how sensitive the function is to changes in its input. The larger the condition number, the more sensitive the function is to changes in its input. The condition number for the function f(x) = 1/cos(x) can be estimated as follows:

K = |f'(x)| / |f(x)|

where f'(x) is the derivative of f(x) and f(x) is the value of f(x) at the point x. At the point x = 1.5708, f'(x) = -1 and f(x) = 0.017453292519943295. Therefore, the condition number is approximately:

K = |-1| / |0.017453292519943295| = 10 raised to power 16

This means that a small change in the input x can cause a large change in the output f(x). For example, if the input x is changed by 1e raised to power of -16, the output f(x) will change by approximately 10 raised to power of 16.

This large condition number is due to the fact that the function f(x) = 1/cos(x) is very sensitive to changes in the input x near the point x = 1.5708. This is because the cosine function is very close to zero at this point.

CAN SOMEONE PLEASE HELP ME WITH THIS PROBLEM. I HAVE TO SOLVE FOR A AND B

Answers

Answer:

b is 10 degrees and a is 64 degrees.

Step-by-step explanation:

Properties of a parallelogram needed for this problem: Opposite angles are congruent and adjacent angles are supplementary, meaning they add to 180 degrees.

This means that in the picture, 2a and 12b+8 are equal, while 2a and 5b+2 are supplementary.

From this we can make two equations:

2a=12b+8

and

2a+5b+2=180

If we subtract 5b+2 in the second equation, both equations will equal 2a. I'll explain why that's good. We end up with:

2a=12b+8

and

2a=180-5b-2

Now, we can set the two equations equal to each other because they both equal the same thing. Then simplify.

12b+8=180-5b-2

17b=170

b=10

Knowing b is 10 degrees, we can easily plug that back into one of our original two equations. I'll choose 2a=12b+8.

2a=12(10)+8

2a=120+8

2a=128

a=64

b is 10 degrees and a is 64 degrees.

Answers

the coordinates of the reflected point are (4, 2).

When a point is reflected about the y-axis, the x-coordinate is negated while the y-coordinate remains the same.

The original point is (-4, 2). If we reflect this point about the y-axis, the x-coordinate becomes positive, and the y-coordinate remains unchanged.

Negating the x-coordinate, we get:

x-coordinate: -(-4) = 4

y-coordinate: 2 (unchanged)

Given the point (-4, 2), reflecting it about the y-axis would result in the x-coordinate changing its sign while the y-coordinate remains unchanged.

Therefore, the coordinates of the reflected point are (4, 2).

Here we have the recipe for 16 crepes:

1/4 cup margarine 3 tbs sugar1/2 cup orange juice 1 tbs grated orange rind1/2 cup toasted almonds.

You want to make 5 crepes for person, for 8 persons, so you need:

The number of yellow marbles = 125

Step-by-step explanation:

Let the number of

Blue marbles = x

Yellow marbles = y

A large jar contains 500 marbles.

x + y = 500

All of the marbles in the jar are either blue or yellow, and there are 3 times as many blue marbles as yellow marbles.

3y = x

Hence, we substitute 3y for ymx in the above equation

12x² + 15x + 8x + 10 has a binomial factor of (3x+2).

What is a Quadratic equation?

ax²+bx+c=0, with a not equal to 0 is a quadratic equation, which is a second-order polynomial equation in a single variable. It has at least one solution because it is a second-order polynomial equation, which is guaranteed by the algebraic fundamental theorem. The answer could be simple or complicated.

We may utilize the factor theorem, which asserts that if a polynomial f(x) has a component (x - a), then f(a) = 0, to identify which polynomial has (3x + 2) as a binomial factor.

In this situation, finding a value of x that reduces 3x + 2 to zero is necessary since we are trying to discover a polynomial that contains (3x + 2) as a component. We obtain x = -2/3 by solving 3x + 2 = 0.

Let's try the polynomials one by one:

(a) 6x³ + 3x² + 4x + 2:

f(-2/3) = 6(-2/3)³ + 3(-2/3)² + 4(-2/3) + 2

= -8/3 - 4/9 - 8/3 + 2

= -32/9,

so (3x + 2) is not a factor.

(b) 12x² + 15x + 8x + 10:

f(-2/3) = 12(-2/3)₂ + 15(-2/3) + 8(-2/3) + 10

= 16/3 - 10 - 16/3 + 10

= 0,

so (3x + 2) is a factor.

(c) 18x³ - 12x² + 9x - 6:

f(-2/3) = 18(-2/3)³ - 12(-2/3)² + 9(-2/3) - 6

= -32/3 + 8/3 - 6 - 6

= -32/3,

so (3x + 2) is not a factor.

(d) 21x⁴ + 7x³ + 6x + 2:

f(-2/3) = 21(-2/3)⁴ + 7(-2/3)³ + 6(-2/3) + 2

= 64/27 - 56/27 - 4 + 2

= 2/27,

so (3x + 2) is not a factor.

Therefore, the only polynomial that has (3x + 2) as a binomial factor is 12x² + 15x + 8x + 10.

What is their total insurance need using the DINK method? O $86,000 O $12,000 O $217,000 O $98,000 O $172,000

Answers

Using the DINK method (Dual Income, No Kids), the total insurance need for Marianne and Roger is $172,000.

The DINK method calculates the insurance need based on the financial obligations and potential future expenses of a couple with dual incomes and no children. To determine their total insurance need, we consider their outstanding debts and potential expenses in case of death.

The calculations are as follows:

Mortgage: $125,000 (outstanding debt)

Car loans: $25,000 (outstanding debt)

Student loans: $22,000 (outstanding debt)

Funeral expenses: $12,000

The total outstanding debt and funeral expenses amount to $184,000.

However, the DINK method suggests subtracting the couple's annual incomes from the total insurance need since they have secure careers and can continue to generate income even in the event of the death of one spouse.

Both Marianne and Roger earn $45,000 annually, so we subtract $45,000 from the total, resulting in a total insurance need of $139,000.

Therefore, the correct answer is $172,000.

Answers

The producer surplus at a price of $250 based on the supply curve, s(x) = 180 + 0.3·[tex]x^{\frac{3}{2} }[/tex] is about $1,326.5

What is a supply curve?

The supply curve is the graphical representation of the price of a good or service and the quantity that manufacturers are willing to supply or provide.

The function for the supply curve is; s(x) = 180 + 0.3·[tex]x^{\frac{3}{2} }[/tex]

When the selling price is $250, the quantity of the product supplied can be found from the equation; s(x) = 250 = 180 + 0.3·[tex]x^{\frac{3}{2} }[/tex]

0.3·[tex]x^{\frac{3}{2} }[/tex] = 250 - 180 = 70

[tex]x^{\frac{3}{2} }[/tex] = 70/0.3 = 700/3

x = (700/3)[tex]\frac{2}{3}[/tex] ≈ 37.9

The quantity of soap supplied when the price is $250, is therefore, about 37.9

The producer surplus can be calculated from the area of a trapezoid formula as follows;

A = (b₁ + b₂) × h/2

Where the length of the bases are; b₁ ≈ 37.9,   b₂ = 0, and the height, h = (250 - 180) = 70

A = (37.9 + 0) × 70/2 = 1326.5

Therefore, at a selling price of $250, the producer surplus is about $1,326.5

4) d. [tex]0.\overline {90}[/tex]

10/11 = 0.9090909...

∴ 10/11 = [tex]0.\overline {90}[/tex]

5) The height of the drone is flying above the ground = [tex]25\dfrac{1}{2}[/tex] ft.

The location of the fossil below the ground = [tex]7\dfrac{1}{4}[/tex] ft.

Taking the ground level as the origin on a number line, we have;

The location of the drone relative to the ground =  + [tex]25\dfrac{1}{2}[/tex] ft. (The positive sign for a point above the origin)

The location of the fossil relative to the ground = [tex]-7\dfrac{1}{4}[/tex] ft. (The negative sign for a point below the origin)

Therefore;

The distance between the drone and the fossil = The difference between the location of the drone and the fossil

The distance between the drone and the fossil = [tex]25\dfrac{1}{2} - \left(-7\dfrac{1}{4} \right)[/tex]

[tex]25\dfrac{1}{2} - \left(-7\dfrac{1}{4} \right) = 25\dfrac{1}{2} + 7\dfrac{1}{4} = 32\dfrac{3}{4}[/tex]

The distance between the drone and the fossil = [tex]32\dfrac{3}{4}[/tex] ft.

Therefore;

The answer is zero since there are no green tiles

2. Quadrilateral ABCD was dilated with the origin as the center of dilation to create quadrilateral A'B'C'D. Which rule best represents the dilation that was applied to quadrilateral ABCD to create quadrilateral A'B'C'D ?

Answers

Answer:

[tex](x,y) => (2.5x,2.5y)[/tex]

Step-by-step explanation:

Given

See attachment for ABCD and A'B'C'D'

Required

Determine the dilation rule

Using AB and A'B' as points of references;

[tex]AB = (-1,2)\ to\ (2,1)[/tex]

[tex]A'B' = (-2.5,5)\ to\ (5,2.5)[/tex]

The dilation factor (k) is calculated as:

[tex]k = \frac{A'B'}{AB}[/tex]

This gives:

[tex]k = \frac{(-2.5,5)}{(-1,2)} \ or\ k = \frac{(5,2.5)}{(2,1)}[/tex]

Factorize

[tex]k = \frac{2.5*(-1,2)}{(-1,2)} \ or\ k = \frac{2.5*(2,1)}{(2,1)}[/tex]

[tex]k = 2.5 \ or\ k = 2.5[/tex]

Hence, the scale factor is 2.5

The dilation rule is:

[tex](x,y) => k(x,y)[/tex]

[tex](x,y) => 2.5(x,y)[/tex]

[tex](x,y) => (2.5x,2.5y)[/tex]

What is the answer when you simplify it?[tex]7^{2} +2(\sqrt{81} +\sqrt{49} )[/tex]

the answer should be 81
I think the answer is 81
