A ball is thrown up from a height of 50m above the ground. Its height after t seconds is given by the function h(t)=50+15t-5t^2 A) what is the balls acceleration at t=3.5s?

B) what is the maximum height the ball reaches?

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
