Question 831172: a bal is tossed off the top of a building. the ball's path can be modelled by
h(t)=-4.9t^2+9.8t+10.2 where h(t) is the height and t is the time.
a) how tall is the school building
b)what is the maximum height the ball will reach? how long does it take to reach this height?
c)how long does it take the ball to hit the ground?

a) 10.2
b) vertex | (1., 15.1)
after one unit of time it reaches a height of 15.1 units
c) h(t)=0 at t = 2.75546
