A ball is thrown straight up from the roof of an 80-foot building and it's height is modeled by the h(t) = â17t2 + 68t + 80, whe
Rasek [7]

Answer:

t = 4

Step-by-step explanation:

Given that:

h(t) = 17t^2 + 68t + 80

When h(t) = 80, we have that:

80 = -17t^2 + 68t + 80\\\\=> 0 = -17t^2 + 68t\\\\=> 17t^2 - 68t= 0\\\\=> 17t(t - 4) = 0\\\\=> t = 0, t = 4\\\\

t = 0 represents when the ball has not been thrown at all, in its initial position.

t = 4 represents the time taken for the ball to hit the roof of the building on its way down.

Hence, our answer is t = 4. (t is in secs)
