Suppose h(t) = -5t2 + 10t + 3 is the height of a diver above the water (in meters), t seconds after the diver leaves the springboard.
When does the diver reach the peak of the dive?

The length of a rectangle is x times the square root of 100. the width is one-half y more than three-halves x. given that the area of the rectangle is 125 cm2, which equation could represent the rectangle in terms of x and y? a) 5xy − 15x = 125 b) 5xy + 15x = 125 c) 15x2 − 5xy = 125 d) 15x2 + 5xy = 125
