The quadratic function that models the height, in feet, of the ball after t seconds is p(x)=-16t�+46t+6 How long does it take for the ball to hit the ground?
------------
I think it's p(t)=-16t�+46t+6 since there's no x on the right side.
---
p(t)=-16t�+46t+6
When it hits the ground, p(t) = 0
----
-16t�+46t+6 = 0
Solve for t.
Use the positive value.
