The answer is -.75 because y=mx+b, and the slope is m.
Answer:
A≅562.45π u²
Step-by-step explanation:
Knowing that the volume the a solid is V=πR²h, then A=πR², therefore
A=π(4√x), integrating on both sides ∫A=4π∫√xdx ⇒ ∫√xdx = 
evaluated (60,77), then

First we can figure out an hourly rate at which cars are washed. To do so, we need to divide 5 cars by 3 hours.
Then we need to multiply 7.5 hours by the rate. This will tell us how many cars are washed in 7.5 hours.

= 12.5 cars
Answer: 8100
Step-by-step explanation:
do the PI formula then divide by 2
