Alain throws a stone off a bridge into a river below. The stone's height (in meters above the water), X seconds after Alain threw it, is modeled by:
h(x) = -5x^2+ 10x + 15
How many seconds after being thrown will the stone hit the water?
seconds
For you to see the picture hood just zoom in to it.

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.
