Cassidy drops her calculus book off of the top of a 220-foot building. the position function of the book is: s(t)= -16t^2 +220. using the velocity function below, find the velocity of the book when t=2 seconds.
lim t-> 2 s(2)-s(t)/2-t

step-by-step explanation:

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
