this rule applies to all negative exponents lol
Between 2pm and 4pm the average rate of change is zero.
I can't see the answer choices for the second part of the question.
There are 10 trucks and 18 tractors
I found that out by multiplying 10 and 1.8 which gave me 18
when u add 10 and 18 u get 28
Consider a circle with radius 
centered at some point 
on the 
-axis. This circle has equation
Revolve the region bounded by this circle across the 
-axis to get a torus. Using the shell method, the volume of the resulting torus is
where 
.
So the volume is
Substitute
and the integral becomes
Notice that 
is an odd function, so the integral over ![\left[-\frac\pi2,\frac\pi2\right]](https://tex.z-dn.net/?f=%5Cleft%5B-%5Cfrac%5Cpi2%2C%5Cfrac%5Cpi2%5Cright%5D)
is 0. This leaves us with
Write
so the volume is
