A firefighter holds a hose 2 m off the ground and directs a stream of water toward a burning building. The water leaves the hose
at an initial speed of 13 m/s at an angle of 30°. The height of the water can be approximated by h (x) = -0.023x² +0.51x+2,
where h (x) is the height of the water in meters at a point x meters horizontally from the firefighter to the building.
