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

10

Reason: h starts at 10 m and decreases to 0 m when the rock hits the water, so the height (range) runs from 0 to 10 meters.
