Answer:Your left hand side evaluates to:
m+(−1)mn+(−1)m+(−1)mnp
and your right hand side evaluates to:
m+(−1)mn+(−1)m+np
After eliminating the common terms:
m+(−1)mn from both sides, we are left with showing:
(−1)m+(−1)mnp=(−1)m+np
If p=0, both sides are clearly equal, so assume p≠0, and we can (by cancellation) simply prove:
(−1)(−1)mn=(−1)n.
It should be clear that if m is even, we have equality (both sides are (−1)n), so we are down to the case where m is odd. In this case:
(−1)(−1)mn=(−1)−n=1(−1)n
Multiplying both sides by (−1)n then yields:
1=(−1)2n=[(−1)n]2 which is always true, no matter what n is

Answer:
D. 10
Step-by-step explanation:
The volume of the cylinder is given by the formula ...
V = πr²h
V = π(4 in)²(13 in) = 208π in³
The volume of a cone 3 inches in radius and 7 inches high is ...
V = (1/3)πr²h = (1/3)(3 in)²(7 in) = 21π in³
Then the ratio of the volume of the cylinder to that of the cone is ...
(208π in³)/(21π in³) ≈ 9.905
You would need to fill the funnel about 10 times to fill the can.
5 is to 7 as is to 49 is to 51
