The volume of a cylinder is pir^2h. So the answer is pi*4^2 times 4. 64 pi.
Both 16 and 8 have a common factor which is 8, so divide both numbers by 8, and you get 2x-1, which is equivalent to 16x-8
Answer:
A
Step-by-step explanation:
Assume Alexandra has already recorded 2 months.
First month:
Fix: 1832.76
total: 1832.76
Last month:
Fix:1832.76
total: 4295.82
Therefore, variable expense of last month is
4295.82-3665.52, oh no! we don't have the answer.
This contradict with our assume.
Assume Alexandra has already recorded 1 month.
Last month:
Fix:1832.76
total:4295.82
Variable = 4295.82 - 1832.76 = A
QP = (8, 9) and | QP | = √145
QP = p - q = (7, 16 ) - ( - 1,7) = ( 7 + 1, 16 - 7) = (8, 9)
given a vector (x , y) then magnitude = √x² + y²
|QP | = | 8² + 9² = √145
