A firefighter aim a fire hose from 4 feet above the ground at a window that is 26 feet above the ground. The equation h=-0.01d^2+1.06d+4 models the path of the water when h equals height in feet. Estimate, to the nearest whole number, the possible horizontal distances (d) in feet between the firefighter and the building.
been out of school for a while and can remember how to do this. if cant give the answer, instructions on how to would be much appreciated.
