A firefighter holds a hose 3 m off the ground and directs a stream of water toward a burning building. The water leaves the hose at an initial speed of 16 m/s at an angle of 30°. The height of the water can be approximated by h(x) = -0.025x² +0.511x+3,
where h(x) is the height of the water in meters at a point x meters horizontally from the firefighter to the building.
