Question 4

4.

A gardener places a sprinkler at the bottom of a gently rising hillside described by the equation y=\frac{2x}{5}. The equation y=-\frac{x^{2}}{25}+x represents the path of the water. If the water splashes onto a rock on the hillside, what is the rock's altitude with respect to the sprinkler?
