x weeks * 7 days/week * 24 hours/day = 168x hours
168x i guess
Answer:
C
Step-by-step explanation:
The total circumference = 5*2 pi = 10pi
You are trying to find (360-44)/360 of the circumference, which simplifies to 79/90.
79/90 *10pi =
79pi/9, which is C
I think you have to first separate the integral:1/(1+v^2) + v/(1+v^2),
so the integral of the first term is ArcTan (v) and for the integral of the second term i recommend you to do a change of variable:
y= 1+v^2
so
dy= 2v
and
v= dy/2and then you substitute:v/(1+v^2) = (1/2)(dy/y)
and the integral is
(1/2) (In y)finally you plug in the initial variables:
(1/2)(In [1+v^2])
so the total integral is:
ArcTan (y) + (1/2)(In [1+v^2])
