1 /3 radius^2 x height 3
Pi/3 *r^2 x 9 3 = 3 pi ^2

r=1, volume = 3 pi
r=2, volume = 12 pi
r=3, volume = 27pi

Answer:

Step-by-step explanation:

Let the rate of commission is x%.

<u>Total earning is:</u>

7500 + 120000*x/100 = 13500
1200x = 13500 - 7500
1200x = 6000
x = 6000/1200
x = 5

Answer:B & E

Step-by-step explanation:

We can first rearrange the function to isolate y. Then, we can find the slope as the function is in the form y=mx+b.

$3x-4y=7\\-4y=-3x+7\\y=\frac{3}{4}x-\frac{7}{4}$

Since parallel lines have the same slope, we can put the slope of 3/4 into the point slope form to get the answer.

<em>For reference, the point-slope form is </em> $y-y_1=m(x-x_1)$

$y+2=\frac{3}{4}(x+4)\\y+2=\frac{3}{4}x+3\\y=\frac{3}{4}x+1$

The first line is found in option E, so option E is one of the correct options.

We can also move the x to the other side, as two of the 5 options have both variables on the left (B and C).

$-\frac{3}{4}x+y=1$

If we multiply the whole equation by -4, we can get rid of the fraction.

$-4(-\frac{3}{4}x+y)=-4(1)\\3x-4y=-4$

Hence, option B is also correct.
