Question

A helicopter hovers 40 ft above the ground. Then the helicopter climbs at a rate of 21 ft/s. Write a rule that represents the helicopter’s height, h, above the ground as a function of time, t. what is the helicopter’s height after 45 s?

Answer 1

A rule that represents the helicopter`s height:
h = 40 + 21 t
where t is time in seconds;
Height after 45 s:
h = 40 + 21 * 45 = 40 + 945 = 985 ft.
