Question

The height in feet (h) of the ball t seconds after it is released can be modeled by: -16t^2+10t+6=h. Find the time in seconds (t) passed before the ball hits the ground (let h=0)

Answer 1

Answer:

1

Step-by-step explanation:

Method 1: Graph, then look at positive zero because time cannot be negative.

Method 2: You just want to find time when the height is zero, so if you set h at zero, you find it is a quadratic; from there you can factor, graph, or use the quadratic formula to solve.
