A paratrooper jumps from a plane at an altitude of 4500 ft and descends at the rate of 20 ft/sec. What is the formula for the paratrooper’s height, h, above the ground after t seconds? a. h = StartFraction 4500 Over 20 EndFraction minus t c. h = 4500 + 20 t b. h = negative 20 t + 4500 d. h = StartFraction 4500 Over 20 EndFraction t
