Answer:
B
Step-by-step explanation:
We are given that:
For all real numbers and they form a region R that is bounded from x = 1 to x = 7. A table of values is given.
We are directed to use a Right Riemann Sum to find the area between the curves of f and g.
Since f is greater than g for all values of x, to find the approximate area between f and g, we can first find the area of f and then subtract the area of g from f.
Using a Right Riemann Sum, the area of f is approximately:
(We multiply the width between each x-coordinate by the right endpoint)
And the area of g is approximately:
Therefore, the area between them will be:
Our answer is B.
Answer:
10 friends
Step-by-step explanation:
we know that
The formula of the sum is equal to
![sum=\frac{n}{2}[2a1+(n-1)d]](https://tex.z-dn.net/?f=sum%3D%5Cfrac%7Bn%7D%7B2%7D%5B2a1%2B%28n-1%29d%5D)
where
a1 is the first term
n is the number of terms (number of friends)
d is the common difference in the arithmetic sequence
In this problem we have
----> the common difference
substitute in the formula and solve for n
![275=\frac{n}{2}[2(5)+(n-1)(5)]](https://tex.z-dn.net/?f=275%3D%5Cfrac%7Bn%7D%7B2%7D%5B2%285%29%2B%28n-1%29%285%29%5D)
![550=n[10+5n-5]\\ \\550=10n+5n^{2} -5n\\ \\5n^{2}+5n-550=0](https://tex.z-dn.net/?f=550%3Dn%5B10%2B5n-5%5D%5C%5C%20%5C%5C550%3D10n%2B5n%5E%7B2%7D%20-5n%5C%5C%20%5C%5C5n%5E%7B2%7D%2B5n-550%3D0)

If kamala's cell phone company adds -$5.75 each month for an over charge and she is overcharged 4 months in a row she will owe, $23 to her phone company.
Answer: 1048576
Working: first you do -4^9 which is -4 to the power of 9.
=-262144
Then -262144 X -4 = 1048576
Hope this helps :D
