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
.
(4/7)-(1/3)
(12/31)-(7/21)
(5/21) is left
Or
In decimal form
(4/7)=0.571
(1/3)= 0.333
0.571-0.333
=0.238
B is 12
c is 6 because you don't count the zero
Answer:
it would be the second opition
Step-by-step explanation:
1- A = B = m²-16
2- D = 4x²-3 proof: (8x³-6x)/2x =2x(4x²-3)/2x simplify to get the answer
