The series of transformations that would map polygon ABCDE onto polygon A'B'C'D'E' is given as follows:

A rotation followed by a translation.

Examples of transformations are given as follows:

For this problem, we have that the inclination of the figure changed, and the figure moved from the second quadrant to the first/fourth, hence the figure underwent a rotation of 90º counterclockwise about the origin.

The figure also had the vertices changed from the rotation, hence a translation was also applied.

The three circles represent the three categories: novel, comics, and textbook.

The overlap between the circles represents the number of students who read more than one category.

The letters A, B, C, and D represent the following regions:

A: Only comics and novel (not textbook)

B: Only textbook and novel (not comics)

C: Only textbook and comics (not novel)

D: All three categories

To answer the questions:

a. To find the number of students who read comics and novel only (region A), we need to add up the number of students who read both comics and novel (5) and subtract from it the number of students who also read textbook (2).

So, the number of students who read comics and novel only is 5 - 2 = 3.

b. To find the number of students who read textbook and novel only (region B), we follow the same process.

We add up the number of students who read both textbook and novel (3) and subtract from it the number of students who also read comics (2).

So, the number of students who read textbook and novel only is 3 - 2 = 1.

c. To find the number of students who read none of the three categories, we start with the total number of students (50) and subtract from it the number of students who read at least one category.

To find the latter number, we add up the number of students who read only novel (3), only comics (9), only textbook (2), and all three (5), which gives us 19. So, the number of students who read none of the three categories is 50 - 19 = 31.

Let us assume that the left right triangle be ABC and the right triangle on the right side be ABD.

So, the larger right triangle would be DAC.

Consider thr outer right triangle DAC.

The length of the hypotenuse DC would be,

DC = CB + BD

DC  = 3 + 7

DC = 10 units

Also right triangle ABC and DAC are similar triangles.

We know that the sides of the smilar triangles are in proportion.

Using the definition of similar triangles for DAC and ABC,

DA/AB = AC/BC = DC/AC

Consider, AC/BC = DC/AC

x/3 = 10/x

The rank of the matrix is 3, since there are three linearly independent rows.

The rank of a matrix is the maximum number of linearly independent rows or columns in the matrix. It is denoted by the symbol "rank(A)" for a matrix A.

To find the rank of the matrix:

[-2, -1, -3, -1] [ 1, 2, -3, -1] [ 1, 0, 1, 1] [ 0, 1, 1, -1]

We can perform row operations to reduce the matrix to row echelon form, which will help us determine the rank.

[tex]R_2 = R_2 + 2R_1 R_3 = R_3 + 2R_1 R_4 = R_4 + R_2[/tex]

This gives us the following matrix:

[-2, -1, -3, -1] [ 0, 0, -9, -3] [ 0, -1, -1, 1] [ 0, 0, -4, -4]

We can see that the third row is not a linear combination of the first two rows, and the fourth row is not a linear combination of the first three rows. Therefore, the rank of the matrix is 3, since there are three linearly independent rows.

The diameter of the circle is 16.04 cm.

The circumference is 50.39 cm

A = πr²

where A is the area of the circle and r is its radius.

square both sides

r = √(A/π) = √(201.06/π) = 8.02 cm

The diameter of the circle is twice the radius, so we can find it by multiplying the radius by 2:

d = 2r = 2(8.02) = 16.04 cm

Therefore, the diameter of the circle is 16.04 cm.

To find the circumference of the circle, we can use the formula:

C = 2πr

where C is the circumference and r is the radius. We already know the value of the radius, so we can substitute it into the formula:

If the train travels at an average speed of 50 Km/h, it would be late by 10 minutes.

Speed is simply referred to as distance traveled per unit time.

It is expressed as:

Speed = distance / time

Given that the train running between two stations 50 Km apart arrives on time if it travels at an average speed of 60 km/h.

The time taken by the train to travel 50 km at an average speed of 60 km/h can be calculated using the formula:

Speed = distance / time

time = distance / speed

time = 50 km / 60 km/h

time = 5/6 hour

Next, if the train travels at an average speed of 50 km/h, the time taken to cover the same distance of 50 km would be:

Speed = distance / time

time = distance / speed

time = 50 km / 50 km/h

time = 1 hour

Now, the difference in time between the two scenarios would be:

time difference = 1 hour - 5/6 hour

time = 1/6 hour

Convert to minutes

time = 1/6 × 60

time = 10 minutes

Therefore, the train would be late by 10 minutes.

Jenny is paying $334.82 per year on credit card interest.

We need to find his annual interest payment which is:

= $1100 * 2% * 12 month

= $264

So, we have an annual interest payment of $264

We must account for interest that accumulates on the interest itself. To calculate this, we can use the formula: A = P (1 + r/n)^(nt) when P is $264, r is 24%, n is 12 and t is 1.

A = $264 * (1 + 0.24/12)^(12*1)

Answer:

h(t) = 11 * sin(π/6 * t) + 15

Step-by-step explanation:

To find the height function h(t) for the piece of gum, we'll use a sinusoidal function since the height of the gum changes in a periodic manner as the tire rotates. The general formula for a sinusoidal function is:

h(t) = A * sin(B * (t - C)) + D

where A is the amplitude, B is the angular frequency, C is the horizontal shift, and D is the vertical shift.

1. Amplitude (A): The amplitude is half the distance between the highest and lowest points of the gum. Since the diameter of the tire is 22 inches, the radius is 11 inches. Thus, the amplitude is 11 inches.

2. Angular frequency (B): Since the gum completes 1 full revolution in 12 seconds, the period of the function is 12 seconds. The angular frequency, B, is found by dividing 2π by the period: B = 2π / 12 = π/6.

3. Horizontal shift (C): Since the gum starts at the three o'clock position, and we want the height to be at its maximum at t = 0, there is no horizontal shift. So, C = 0.

4. Vertical shift (D): The platform is 4 inches above the ground, and the radius of the tire is 11 inches. Therefore, the midpoint of the gum's motion is 4 + 11 = 15 inches above the ground. So, D = 15.

Now we can write the height function h(t):

h(t) = 11 * sin(π/6 * t) + 15

The displacement of the particle at time t is 11t - t², and the total distance traveled by the particle in 2 seconds is 9 meters.

The displacement of a particle moving along a straight line can be calculated by finding the area under the velocity-time graph. In this case, the velocity function is v(t) = 11 - 2t for 0 ≤ t ≤ 2.

To find the displacement at time t, we need to find the area under the velocity-time from t = 0 to t = t. The formula for displacement is the integral of the velocity function with respect to time:

s(t) = ∫v(t) dt = ∫(11 - 2t) dt = 11t - t²

Therefore, the displacement of the particle at time t is given by s(t) = 11t - t².

To find the total distance traveled by the particle in 2 seconds, we need to consider both the forward and backward motion. Since the velocity is decreasing at a constant rate of 2 m/s², the particle will come to rest at t = 11/2 seconds.

The total distance traveled by the particle in 2 seconds is given by:

d(2) = ∫|v(t)| dt =  [tex]\int\limits^{11/2}_0[/tex] v(t) dt + [tex]\int\limits^2_{11/2}[/tex]|v(t)| dt from 11/2 to 2

= [[tex]\int\limits^{11/2}_0[/tex](11t - t²) ] + [[tex]\int\limits^2_{11/2}[/tex](-11t + t²) ]
