A golf ball is hit from a hill, and its height can be modeled by h(t)= -16 + 32t + 48, where he is the
1 answer:
Answer:
1 second
Step-by-step explanation:
We assume your model is intended to be ...
h(t) = -16t^2 +32t +48
Setting this equal to 64, we can find t ...
64 = -16t^2 +32t +48
t^2 -2t +1 = 0 . . . . . . subtract 64 and divide by -16
(t -1)^2 = 0 . . . . . . . . factor the square
t = 1 . . . . . . . . . . . . . the only solution
It will take the ball 1 second to reach a height of 64 feet.
