Question

While hiking, Marek throws a rock off a cliff that is roughly 10 meters above a lake. This situation is modeled by the equation h=−4.9t2+10 , with h representing the height in meters and t the time in seconds. If you were to set up a table to determine when the rock hits the water, what would be a reasonable scale for the range?(1 point)

Answer 1

2

Reason: the rock's height ranges from 10 m down to 0 m, so using a 2-meter step (10, 8, 6, 4, 2, 0) gives a reasonable table to see when h reaches 0.
