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 
.
m is an unknown number that is being decreased by 7.
OPTION A IS WRONG BECAUSE MATHEMATICALLY IT IS WRITTEN AS
B IS WRONG BECAUSE IT MEANS
C IS WRONG BECAUSE IT MEANS
BUT D IS THE ANSWER BECAUSE IT MEANS
SINCE m IS TREATED AS AN UNKNOWN NUMBER.
GOODLUCK!!!!
Answer:
180
Step-by-step explanation:
Area of troiangle=180
A+B+C=180
22+90+B=90
112+B=180
B=180-112
B=68
perimeter=A+B+C
22+90+68=180
Just try different ways to find a common denominator, add from there and then simplify.
The answer is 27/23. The way you listed the answers is confusing so I’m not giving a letter. Because [17+10]/[17+6]= 27/23
