Question 1052592: henry jumps from a platform 10 meters above the surface of the water. the height of henry's jump can be modeled by the function h(t) = -5.3t^2 + 4.8t +10, where t is time in seconds after the jump. At what time t is henry 3 meters above the water?

You can put this solution on YOUR website!
h(t) = -5.3t^2 + 4.8t +10
-----
h(t) = -5.3t^2 + 4.8t +10 = 3
Solve for t
====================
It's a quadratic.
