Answer:
Sum=24
Mean=8
Step-by-step explanation:
To find the sum of all the numbers you simply would do 8+7+9.
That is 24.
When finding mean you add up all your numbers then divide by the total number of number (I know that sounds a bit confusing. In this case there are only 3 numbers, so that is the one you will use for dividing)
Your equation would look like this
24
_
3
Once you divide you should get 8 as your mean or average in other terms.
Lim 2^x-3 = lim 2^(1/x^3) = 2^(1/inf) = 2^0 = 1
x -> infinity
The function approaches 1

Step-by-step explanation:
FOIL
(1/2)h*B1+ (1/2)h*B2=A
subtract the B2 term
(1/2)h*B1 = A- (1/2)h*B2
multiply by 2
h*B1 = 2A - h*B2
divide by h
