V = (-7,-4)
8v would be 8 times both numbers
8v = (8*-7, 8*-4)
8v = (-56, -36)
magnitude = square root( -56^2 + -36^2)
= sqrt(3136 + 1296)
= sqrt(4432 )
= 4 sqrt(277)
Since the "size in square feet" is on the X-axis it is represented by the X in the equation. And Y is expected property tax
It is giving you a X-value of 3100. So you just have to plug 3100 into the X spot and solve for Y
y=.392(3100)+638.118
y=1853.318
So the third answer.

Answer:
254.5 Inches Cubed
Step-by-step explanation:
Formula for Finding the Volume of a Cylinder: 
The radius is 3 inches.

The height is three times the radius.
Multiply the radius by three to get the height.

The height is 9 inches.
Use the formula to find the volume.

The exact volume is 81
inches cubed.
≈ 254.47
254.47 ≈ 254.5
The volume of the cylinder should be about 254.5 inches cubed.
