the function f(t)=20sin(10t)+25 models the height of a specific seat on a ferris wheel above the ground at time, t. over what time, t, is the person riding at least 40 feet in the air?

4.86

Step-by-step explanation:

The function f(t) denotes the height of a specific seat on a Ferris wheel above the ground level at time t.

The function is f(t) = 20 Sin 10t +25 (1)

It is asked in the question that at what time a person riding at least 40 feet in the air.

Hence, we can write, 40= 20 Sin 10t +25

⇒ 20 Sin 10t =15

⇒ Sin 10t =  15/20

⇒ 10t = Sin⁻¹ (15/20) =48.59

⇒ t = 4.86 (Approximate) (Answer)
