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)

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.
