Given:
D=165 feet and the frequency of the motion is 1.6 revolutions per minute.
Solution:
The radius is half of the diameter.
The radius of the wheel is 82.5 feet.
As we know: 
Substitute the value of T in the above formula.
If the center of the wheel is at the origin then for 
the rest position is 
.
This can be written as:
The actual height of the rider from the ground is:
The required equation is 
.

Can’t see the model.......................
Step-by-step explanation:
f(x) = x² - 4
y = x²-4
x = y²-4
x + 4 = y²
Since the triangle has equal sides it will carry onto it self at 120, since it can rotate 360 grades only and it has 3 sides so it will rotate in one third of 360 so 120
i hope i helped you
