Aferris wheel has a radius of 10 m, and the bottom of the wheel passes 1 m above the ground. if the ferris wheel makes one complete revolution every 18 s, find an equation that gives the height above the ground of a person on the ferris wheel as a function of time. (let y be the height above the ground in meters and let t be the time in seconds. assume that when t = 0 the person is 11 m above the ground and going up.)
y =11+9sin(π9t)

step-by-step explanation:

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq

just sum

10 + 10 = 20
