The value of the scale factor for the similar figures is 1/2

From the question, we have the following parameters that can be used in our computation:

The similar figures

The corresponsing sides of the similar figures are

Original = 8

New = 4

Using the above as a guide, we have the following:

Scale factor = New /Original

substitute the known values in the above equation, so, we have the following representation

Scale factor = 4/8

Evaluate

Scale factor = 1/2

Hence, the scale factor for the similar figures is 1/2

Taking the inverse Laplace transform of each term using the table of Laplace transforms, we get: f(t) = -1/2 + 2e^t

(a) To find the inverse Laplace transform of F(s) = 1/(s+1)(s+3)(s-3), we can use partial fraction decomposition as follows:

1/(s+1)(s+3)(s-3) = A/(s+1) + B/(s+3) + C/(s-3)

Multiplying both sides by (s+1)(s+3)(s-3), we get:

1 = A(s+3)(s-3) + B(s+1)(s-3) + C(s+1)(s+3)

Expanding and equating coefficients of s^2, s and the constant term, we get:

A = 1/24

B = -1/8

C = 1/24

Therefore, we have:

F(s) = 1/24(s+1) - 1/8(s+3) + 1/24(s-3)

Taking the inverse Laplace transform of each term using the table of Laplace transforms, we get:

f(t) = 1/24(e^(-t) - e^(-3t)) - 1/8e^(-3t) + 1/24e^(3t)

(b) To find the inverse Laplace transform of F(s) = s(s-1)(s+2), we can use partial fraction decomposition as follows:

s(s-1)(s+2) = As^2 + Bs + C

Multiplying both sides by (s-1)(s+2), and setting s=0, 1, and -2, we get:

C = 0

-2A + 2B = -2

2A + B = 1

Solving for A and B, we get:

A = -1/2

B = 2

Therefore, we have:

F(s) = -1/2s + 2/(s-1)

Step-by-step explanation:

Let's assume that h=2

-9(2)+9(2)=0

-18+18=0

And if we assumed that h=9

Then: - 9(9)+9(9)=0

- 81+81=0

Thus, h can be any number

Answer: \(\Large\boxed{Point~B'~=~(-4,~-2)}\)

Step-by-step explanation:

Given information

Point B = (-2, -4)

Reflection line: y = x

Concept:

When reflecting over the line y = x, the position of y and x in the original coordinate switches places.

This is because it is " y = x ", assuming that they could interchange

Find the coordinate of Point B'

Original (x, y) = (-2, -4)

Point B' = (x', y') = (y, x) = \(\Large\boxed{(-4,~-2)}\)

Please refer to the attachment below for a graphical understanding

Hope this helps!! :)

Please let me know if you have any questions

The coordinates of B' after the reflection over the line y = x are (-4, -2).

Given that a point B = (-2, -4) has been reflected over the line x = y, we need to find the coordinates of the reflected point B'.

To find the coordinates of point B' after a reflection over the line y = x, we need to understand what a reflection over this line means.

The line y = x is a diagonal line that passes through the points where the x-coordinate and the y-coordinate are equal.

It has a 45-degree angle with both the x-axis and the y-axis. When you reflect a point over this line, you essentially swap its x and y coordinates.

Let's take point B(-2, -4) as an example. To reflect this point over the line y = x, we swap its x and y coordinates:

New x-coordinate of B' = Old y-coordinate of B = -4

New y-coordinate of B' = Old x-coordinate of B = -2

So, the coordinates of B' will be (y, x) = (-4, -2).

Step-by-step explanation:

Under a reflection in the x- axis

a point (x, y ) → (x, - y ) , then

A (4,  2 ) → A' (4, - 2 )

B (7, 0 ) → B' (7, 0 )

C (9, 3 ) → C' (9, - 3 )

A translation of a shift to the left of 3 units is a horizontal shift.

This means subtracting 3 fro the x- coordinate and leaving the y- coordinate

A' (4, - 2 ) → A'' (4 - 3, - 2 ) → A'' (1, - 2 )

B' (7, 0 ) → B'' (7 - 3, 0 ) → B'' (4, 0 )

To estimate the number of eighth-grader students in your school who find it relaxing to listen to music, you consider two samples.Fifteen randomly selected members of the band and every fifth student whose name appears on an alphabetical list of eighth-grade students.

The work for this estimation is as follows:Sample 1: Fifteen randomly selected members of the band.If the band is a representative sample of eighth-grade students, we can use this sample to estimate the proportion of students who find it relaxing to listen to music.

We select fifteen randomly selected members of the band and find that ten of them find it relaxing to listen to music. Therefore, the estimated proportion of eighth-grader students in your school who find it relaxing to listen to music is: 10/15 = 2/3 ≈ 0.67.Sample 2: Every fifth student whose name appears on an alphabetical list of eighth-grade students.Using this sample, we take every fifth student whose name appears on an alphabetical list of eighth-grade students and ask them if they find it relaxing to listen to music.

We continue until we have asked thirty students. If there are N students in the eighth grade, the total number of students whose names appear on an alphabetical list of eighth-grade students is also N. If we select every fifth student, we will ask N/5 students.

we need N/5 ≥ 30, so N ≥ 150. If N = 150, then we will ask thirty students and get an estimate of the proportion of students who find it relaxing to listen to music.To find out how many students we need to select, we have to calculate the interval between every fifth student on an alphabetical list of eighth-grade students,

which is: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100, 105, 110, 115, 120, 125, 130, 135, 140, 145, 150

We select students numbered 5, 10, 15, 20, 25, and 30 and find that three of them find it relaxing to listen to music. Therefore, the estimated proportion of eighth-grader students in your school who find it relaxing to listen to music is: 3/30 = 1/10 = 0.10 or 10%.Thus, we can estimate that the proportion of eighth-grader students in your school who find it relaxing to listen to music is between 10% and 67%.

To estimate the number of eighth-grade students who find it relaxing to listen to music, you can use two sampling methods: sampling from the band members and sampling from an alphabetical list of eighth-grade students.

Sampling from the Band Members:

Selecting fifteen randomly selected members of the band would give you a sample of band members who find it relaxing to listen to music. You can survey these band members and determine the proportion of them who find it relaxing to listen to music. Then, you can use this proportion to estimate the number of band members in the entire eighth-grade population who find it relaxing to listen to music.

Sampling from an Alphabetical List:

Every fifth student whose name appears on an alphabetical list of eighth-grade students can also be sampled. By selecting every fifth student, you can ensure a random selection across the entire population. Surveying these selected students and determining the proportion of those who find it relaxing to listen to music will allow you to estimate the overall proportion of eighth-grade students who find it relaxing to listen to music.

Both sampling methods can provide estimates of the proportion of eighth-grade students who find it relaxing to listen to music. It is recommended to use a combination of these methods to obtain a more comprehensive and accurate estimate.

A quadratic equation is a second-degree polynomial equation in a single variable. In other words, it is an equation of the form \(ax^2 + bx + c = 0\), where x is the variable, and a, b, and c are constants.

The goal of solving a quadratic equation is to find the values of x that make the equation true. There are several methods for solving quadratic equations, including factoring, completing the square, and using the quadratic formula.In the given question,

To solve the quadratic equation x² - 14x - 49 = 0 ,

we can use the quadratic formula:

\(x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}\)

where a = 1, b = -14, and c = -49.

Plugging in these values, we get:

\(x = \frac{-(-14) \pm \sqrt{(-14)^2 - 4(1)(-49)}}{2(1)}\)\(x = \frac{14 \pm \sqrt{196 + 196}}{2} = \frac{14 \pm \sqrt{392}}{2} = \frac{14 \pm 14\sqrt{2}}{2} = 7 \pm 7\sqrt{2}\)

The goal of solving a quadratic equation is to find the values of x that make the equation true. There are several methods for solving quadratic equations, including factoring, completing the square, and using the quadratic formula.

In the given question,

To solve the quadratic equation x² - 14x - 49 = 0, we can use the quadratic formula:

x = (-b ± √(b² - 4ac)) / 2a

where a, b, and c are the coefficients of the quadratic equation ax² + bx + c = 0.

In this case, a = 1, b = -14, and c = -49. Substituting these values into the quadratic formula, we get:

x = (-(-14) ± √((-14)² - 4(1)(-49))) / 2(1)

x = (14 ± √(196 + 196)) / 2

x = (14 ± √392) / 2

x = (14 ± 14√2) / 2

Simplifying this expression, we get:

x = 7 ± 7√2

The solution to the initial-value problem t du/dt = t^2 * 3u, t > 0, u(3) = 18 is given by the function u(t) = (18/3^3) * t^3.

To solve the initial-value problem, we can separate variables and integrate both sides. Starting with the given equation t du/dt = t^2 * 3u, we can rearrange it as du/u = 3/t dt. Next, we integrate both sides. The integral of du/u is ln|u|, and the integral of 3/t dt is 3 ln|t| + C, where C is the constant of integration.

Therefore, we have ln|u| = 3 ln|t| + C. Exponentiating both sides, we get |u| = e^(3 ln|t| + C). Since e^C is just another constant, we can rewrite the equation as |u| = K * t^3, where K = e^C. Finally, using the initial condition u(3) = 18, we can determine the value of K: |18| = K * 3^3, which gives us K = 2. Plugging in K and removing the absolute value, we obtain u(t) = (18/3^3) * t^3 as the solution to the initial-value problem.

Step-by-step explanation:

Let x = number of 50.00 notes.

They are worth 50x

Then, 2x = number of 20.00 notes.

They are worth 2x * 20 = 40x

50x + 40x < 1100

9x < 110

x < 12.2

Answer: 12

Check:

x = 12   (number of 50.00 notes)
