Please help Ming throws a stone off a bridge into a river below. The stone's height (in meters above the water), x seconds after Ming threw it, is modeled by: h(x)= -5*(x-1)^2+45 What is the maximum height that the stone will reach?

45 feet.

Step-by-step explanation:

h(x) = -5(x - 1)^2 + 45

The maximum height occurs when  the time x  is such that -5(x - 1)^2 is a maximum  which is 0. This occurs when x = 1. when x = 1.

So the answer is 45 feet.

the answer is 375 miles
