Answer:
5 seconds
Step-by-step explanation:
When the ball returns to its original height, it will be 96 ft from the ground. That means we want to solve for t ...
h(t) = 96
96 +80t -16t^2 = 96
16t(5 -t) = 0 . . . . subtract 96 and factor
This equation is true for t=0 and for t=5.
After 5 seconds, the ball will pass the top of the building on the way down.

Answer:
a = 15/4.
Step-by-step explanation:
(2a-5)/6 = 5/12
Cross multiply:
12(2a - 5) = 5*6
24a - 60 = 30
24a = 90
a = 90/24
a = 15/4.
