Answer:
B
Step-by-step explanation:

Radius= diameter ÷2
r= 32 ÷2
r= 16

Substitute r= 16,


Divide the denominator and numerator by 128:

Thus, the answer is B.
First do
3x + -5x = -2x
Then do
-2x + 5x = 3x
Lastly do
3x+1
In the standard form of the equation
![\\ \ f(t)=Acos[b(t\pm c)]+k\\ \\](https://tex.z-dn.net/?f=%20%5C%5C%20%5C%20f%28t%29%3DAcos%5Bb%28t%5Cpm%20c%29%5D%2Bk%5C%5C%20%5C%5C%20)
The middle line =k
For our given problem
f(t) = 40cos (80t + 20)
On comparison we get k=0
Hence middle line=0
I need to see the rest to solve the k but I know that the direct is 50. is there any other part to it so I can solve it
3 miles X 4 times a week is =12 miles a week so 12 miles X 6 =72 miles
