<span>You first need to calculate the circumference as that will give you the distance in one revolution.
Then you multiply the answer you get by 8
Circumference = pi*diameter = 22pi 8 revolutions = 8*22*pi = 176pi

F(x)= -1/2 ( square root x+3 ) x2-3
-2f(x)= ( square root x+3)
4f^2(x)= x+3
f^-1(x)= 4x^2-3
Answer:
Option D. -0.901
Step-by-step explanation:
we know that
<u>The correlation coefficient</u> r measures the strength and direction of a linear relationship between two variables. The value of r is always between +1 and –1
Using a Excel tool (Correl function)
The value of coefficient r is -0.9006876
Round to three decimal places
r=-0.901
