For Club B we calculate using the formula

[tex]m=\frac{y2-y1}{x2-x1}[/tex][tex]\begin{gathered} m=\frac{42-21}{2-1} \\ m=\frac{21}{1}=21 \end{gathered}[/tex]The value is 21.

For Club C we apply the same formula and use the poins shown in the graphic

[tex]\begin{gathered} m=\frac{70-40}{3-1} \\ m=\frac{30}{2} \\ m=15 \end{gathered}[/tex]For club D the slope is the value that is paid each month

Triangle ABC is rotated to create the image A'B'C'.

Which rule describes the transformation?

(x, y) - (x.-y)

(x,y) - (y.x)

(x,y) - (-x.-y)

(x,y) - (-y.-x)

Option C, (x, y) - (-x, -y) is the rule which describes the **transformation**.

A rotation in **geometry** is a change of a shape that involves turning it by a given number of degrees around a certain point known as the **center of rotation** and is denoted as R(0,x), wherein x is an angle of rotation around a center point O.

Assume triangle ABC's subsequence to be (x, y) and the angle of rotation for rotating **triangle** ABC to A'B'C' to be 180° or -180° about the center of rotation (0,0).

That is under R(0,0),180°.

The image formed is (-x,-y).

The resulting picture will contain a triangle ABC in the first quadrant of the graph and a triangle A'B'C inside the third quadrant with the center of rotations (0,0).

1. Compare two spheres. The first has a diameter of 4 inches.

The second sphere has a diameter of 428 inches.

Determine the ratio of the volume of the large sphere to the volume

of the small sphere.

Ratio =

**Answer:**

1,225,043

**Step-by-step explanation:**

You want the **ratio of volumes** of spheres **428 inches** and **4 inches** in **diameter**.

The volume of a sphere in terms of its diameter is ...

V = (π/6)d³

The ratio of the volumes of the larger to smaller sphere is ...

[tex]\dfrac{V_{large}}{V_{small}}=\dfrac{\pi/6\cdot428^3}{\pi/6\cdot4^3}=\left(\dfrac{428}{4}\right)^3=107^3=\boxed{1,\!225,\!043}[/tex]

**The ratio of volumes is 1,225,043**.

The ratio of the **volume** of the large sphere to the volume of the small sphere is 1225043:1

The following is the formula for finding the volume of a sphere:

V = [tex]\frac{4}{3} \pi r^3[/tex]

Now, the normal assumption is that we must use the formula to calculate the **volume** of both spheres in order to compare. However, observe that in comparing the volume of two different spheres, the only difference between them is the radius, thus we can compare the two spheres directly in this way:

[tex]\frac{(radius of sphere B)^3 }{(radius of sphere A)^3}[/tex]

Although, I think you only need the answers from part C ( which is the graph I've including) to answer question 6

Question 6 asks us to determine the period of the function.

Looking at the height of the blade tip, it varies in a sinusoidal manner.

Thus, the period is the distance between successive same heights on the table.

The function takes 360 degrees to return to its same value. At angle zero, the height was 150ft and it was still 150 ft at 360 degrees.

**Thus the period is 360 degrees. **

Find the equation of the line that is perpendicular to the line y =5x + 6 and passes through the point (-3,3). Write the equation in point slope form.

The **point-slope** form of equation of the line **perpendicular **to the line y = 5x + 6 nd passing through (-3,3) is x + 5y = 12.

If two lines are perpendicular to each other, then the** product of slopes** of these two lines is equal to -1.

The provided line is y = 5x + 6,

The slope M₁ of the line is equal to the coefficient of x,

M₁ = 5

Let the slope of the **perpendicular **line is M₂,

So, we can write,

M₁M₂ = -1

M₂ = -1/5.

Now, we can use the point slope form of the equation of line, according to which is if line passes through (a,b) and have slope m then the equation of the line will be,

(y-a) = m(x-a)

This form of line is called** Point-slope form **of line.

24. a. The 2004 Toyota Corolla is advertised by Toyota as getting 32 miles to the gallon while driving around town. We will assume that Toyota is rounding this number to the units place. The fuel tank holds 13.2 gallons. If the tank is full, how many miles could drive before running out of gas? Round according the guidelines.

b. AAA ran tests on fuel efficiency and found the 2004 Toyota Corolla actually got 28.9 miles per gallon driving around town. Using AAA's estimate, how long could you drive before running out of gas? Round according the guidelines.

c. How many miles less does the AAA estimate predict you can get on a single tank of gas? Round according the guidelines.

a) If the tank is full, using **mathematical operations** based on the 2004 Toyota Corolla, you will run 422.4 miles before running out of gas, according to Toyota's advert.

b) Using AAA's estimate, one could drive 381.4 miles before running out of gas.

c) Based on the AAA estimate, on a single tank of gas, you can predict that you will get 40.9 miles less.

What are mathematical operations?The **mathematical operations** include subtraction, addition, division, and multiplication.

For our purpose, we have used the mathematical operations of **multiplication** and **subtraction** to determine the above values.

Claimed mileage per gallon, according to the Toyota advert = 32 miles

The number of gallons of gas in Toyota Corolla's full tank = 13.2 gallons.

AA fuel efficiency on 2004 Toyota Corolla = 28.9 mpg

a) Miles to run before running out of gas (Toyota advert) = 422.4 (32 x 13.2) miles

b) Miles to run before running out of gas (AAA rating) = 381.48 (28.9 x 13.2) miles

c) The **difference** in miles between (a) and (b) above = 40.92 (422.4 - 381.48) miles
