Answer:

The measure of C'T' after rotation of transformation is option (B) square root of 17 is the correct answer.

Step-by-step explanation:

What is a rotation transformation?

A rotation is a transformation that turns the figure in either a clockwise or counterclockwise direction on the coordinate plane.  In both transformations the size and shape of the figure stays exactly the same.

For the given situation,

The graph shows the triangle CAT.

If a rotation takes triangle CAT to C'A'T',

then from the definition of rotation transformation the size and shape of the figure stays exactly the same.

Thus the measure of C'T' is same as CT.

Hence we can conclude that the measure of C'T' after rotation of transformation is option (B) square root of 17 is the correct answer.

The description of the one transformation that maps ∆ABC to ∆A'B'C' is a rotation counterclockwise, 90 degrees, with the center at the origin

A rotation transformation can be described as the angular motion of a rigid, geometric figure around a point

The vertices on the triangle ∆ABC are;

The vertices on the triangle ∆A'B'C' are;

The rotation of a point A(x, y), 90° counterclockwise about the origin gives the point A'(-y, x)

The reflection of a point (x, y) across the y–axis gives the point A'(-x, y)

Therefore;

The coordinates of the vertices of∆ABC following a 90° counterclockwise rotation gives;

A(-5, -2) → A'(2, -5)

B(-7, -4) → B'(4, -7)

C(-5, -5) → C'(5, -5)

Therefore;

The transformation that maps ∆ABC to ∆A'B'C' is therefore a rotation of 90° counterclockwise about the origin

The value of x for the given arithmetic sequence is x = 4.

A series of numbers called an arithmetic progression or arithmetic sequence has a constant difference between the terms. An arithmetic progression with a common difference of 2 is found, for instance, in the numbers 5, 7, 9, 11, 13, and 15.

Given,

First three terms of an arithmetic sequence are x, 2x + 4, 5x

The difference of 1 and 2 term equals the difference of 3 and 2 term.

⇒ 2x + 4 - x = 5x - 2x - 4

⇒ x + 4 = 3x - 4

⇒ 2x = 8

⇒ x = 4

Algebra - The total cost of the fruit 8.26

What is Algebra ?

One of the many branches of mathematics is algebra. Algebra, which is a common thread throughout practically all of mathematics, is broadly defined as the study of mathematical symbols and the rules for manipulating these symbols in formulas.

Given that,

The cost of all fruit is = 1.75/pound

William bought Peaches = 2(2/5)pounds = 12/5pounds

William bought Apricot = 2(1/3)pounds = 7/3pounds

The cost of Peaches = 12/5 x 1.75

                          = 12 x 0.35

                          = 4.2

The cost of Apricot = 7/3 x 1.75

                                = 7 x 0.58

                                = 4.06

Total cost of the fruit = 4.2 +4.06

                                   = 8.26

Hence, the total cost of the fruit is 8.26

If you have ​$50 in your bank account and each week you plan to deposit ​$8 from your allowance and ​$20 from your paycheck. The number of  weeks from now that you will have ​$210 in your bank​ account is: 5.71w.

The given equation is:

b=50+​(20+8​)w

Where:

b  is the amount in your account after w weeks.

w = Number of week

Hence,

b = 50+​(20+8​)w

b = 50+28w

b-50 = 28w

(b-$50)/28 = w

(210-$50)/28 = w

A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y.

Where, x and y are individual amount of two quantities.

And, Total quantity gives after combine as x + y.

Given that;

Length of cell A = 4 x 10⁻⁵

Length of cell B = 0.000002 = 2 x 10⁻⁶.

Now,

Length of cell B into scientific notation = 2 x 10⁻⁶

Hence, The ratio of the length of cell A to cell B =  4 x 10⁻⁵ / 2 x 10⁻⁶

                                                                          = 2 x 10⁻⁵⁺⁶

                                                                          = 2 x 10¹

The x intercepts are 0, 1, -2, 2.

What is intercepts?

The term "intercept" refers to the x- and y-intercepts of of a given equation. The x-intercept is the point at which a line crosses the x-axis and the y-intercept is the point at which a line crosses the y-axis.

In the linear equation, we have the general form as y=mx+b

where m and b are constants.

We have to find the x intercept of the given function.

Given equation is [tex]x^{4} +x^{3} -4x^{2} -4x[/tex]

put this equation equals to 0

x^{4} +x^{3} -4x^{2} -4x = 0

[tex]x(x^{3} +x^{2} -4x-4)=0[/tex]

from this x = 0

x =1 is also the root of the equation

we get [tex]x^{2} -4=0[/tex]

x = -2, 2

The most appropriate choice of percentage will be given by-

The store have to increase the price of the item by [tex]11\frac{1}{9}[/tex] %  in order to sell it for the original amount.

What is Percentage?

Percentage is a ratio expressed as a percentage of 100.

Let the original price be x

Percentage decrease in price due to sale = 10%

Decrease in price due to sale = [tex]\frac{10}{100} \times x[/tex]

                                                  = [tex]\frac{x}{10}[/tex]

New price = ([tex]x - \frac{x}{10}[/tex])

                 = [tex]\frac{10x-x} {10}[/tex]

                 = [tex]\frac{9x}{10}[/tex]

Now,

Increase in price from [tex]\frac{9x}{10}[/tex] to [tex]x[/tex] = [tex]\frac{x}{10}[/tex]

Percentage by which the store have to increase the price of the item in order to sell it for the original amount =

The predicted distance of the ball is 271.93 feet.

The speed of an item, which is a scalar quantity in everyday usage and kinematics, is the size of the change in that object's position over time or the size of the change in that object's position per unit of time. Speed is what it means. the speed at which an object's location changes in any direction. The distance travelled in relation to the time it took to travel that distance is how speed is defined. Since speed simply has a direction and no magnitude, it is a scalar quantity.

Given Data

The speed, s, is measured in miles per hour, and distance, y, is

measured in yards.

The line of fit is given by ý = 3.98 +53.59s.

When s = 5 sec

A statistics professor plans classes so carefully that lengths of her classes are uniformly distributed between 46.0 and 56.0 minutes.The Probability that a given class period runs between 51.5 and 51.75 minutes is 0.025.

The density of a place refers to the quantity of things—which may include people, animals, plants, or objects—there are in it. Divide the number of objects by area's measurement to determine density. A country's population density is calculated by dividing its total population by its area, expressed in the square kilometers or miles.

A flat distribution with the same probability density for each number is called a uniform distribution. The area beneath the distribution's graph must be 1. This distribution has a range of 10.0 and runs from 46.0 to 56.0 minutes (56.0-46.0). Since the density must be 1/10, 10.0*0.1 Equals 1.0.

Multiply the range between the numbers by the probability density to get the likelihood of being between two numbers

range: 50.75-50.5 = 0.25

0.25*0.1 = 0.025

P(50.5 < x < 50.75) = 0.025

By completing squares, we will see that the two solutions of the quadratic equaiton are:

m = -7 + √(145)/2

m = -7 - √(145)/2

Here we have the quadratic equation:

m^2 + 7m - 51/4 = 0

If we multiply both sides by 4, we will get

4m^2 + 28m - 51 = 0

Now, remember the relation:

(a + b)^2 = a^2 + 2ab + b^2

Then to complete the squares we can write:

(2m)^2 + 2*14*m + (14)^2 - (14)^2 - 51 = 0

(2m + 14)^2 - 14^2 - 51 = 0

(2m + 14)^2 = 145

We already completed squares, now the solutions are:

2m = -14 ± √145

m = (-14 ± √145)/2

m = -7 + √(145)/2

∵ There are 142 who prefer carrots

∵ There are 250 all

∴ The fraction represents who prefer carrots is

We must simplify the fraction by divide up and down by the same number until getting the simplest form

∵ 142 and 250 can divide by 2

∵ 71 and 125 can not divide by any number

∴ The fraction is 71/125

∴

∵ There are 97 who prefer peas

∵ There 250 all

∴ The fraction represents who prefer peas is

∵ 97 and 250 can not divide by the same number

∴ The fraction is 97/250

∴ The ratio is 97: 250
