<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

Answer:
n = -23
Step-by-step explanation:
3n + 7 - 11n - 31 = 160
Step 1: Combine like terms
-8n - 24 = 160
Step 2: Simplify
-8n = 184
n = -23
Answer:
See below.
Step-by-step explanation:
Average rate of change =( R(1008) - R(1001) ) / (1008 - 1001)
=[ 12(1008) - 0.005(1008)^2 - (12(1001) - 0.005(1001)^2) ] / 7
Answer:
The true statement is that the expression is satisfied for n = -2.
Step-by-step explanation:
Given:
To check:
Left hand side = Right-hand side ( for n = -2)
Proof :
For n = -2
Consider Left hand side of the equation given above.
∴ Left hand side = 4n
= 4×(-2) ......................for n = -2
= -8
Consider Right-hand side of the equation given above
∴ Right-hand side =
Now we get Left hand side equal to Right hand side
i.e. Left hand side = Right hand side
i.e. is true for n = -2
