You are standing at a base of a Ferris Wheel which is 4 m above ground while your friend is riding. The Ferris Wheel is 8m in diameter. Describe how the shape of the sine curve models the distance your friend is to the platform you are on. Identify the function that will model this situation as well as a function that will model the if we measure his distance to the ground. In your explanation use the following terms:

Sine
Function
Repeat
Rotate
Amplitude
Period
Intercept
Maximum
Minimum
Axis of the curve

Clearly you want somebody to do this assignment for you.
You have shown no work of your own, nor have you shown us where your difficulty is.
From the data, the only information given would be the amplitude of the sine function and perhaps a vertical shift.

clearly the axle is 8m above the ground, and the radius is 4m. So, you can start out with a function that describes the distance to the ground. It will look something like

h(t) = 4+4sin(t)

See where you can go from there. I assume the platform is at the wheel's lowest point.
