A helicopter hovers 40 ft above the ground. ＀en the helicopter climbs See Problem 2. 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?

h = rt

945ft

Step-by-step explanation:

Let h be height, r be rate and t be time.

The rule can be written as h = rt

The height after the 40 seconds can be calculated using the formula. We substitute 21ft/s for r and 46s for t.

The height is thus h = 21 * 45 = 945ft
