Answer:
b=4
Step-by-step explanation:
So, we have the function
. We need to find b such that the average rate of change or the slope is -1/8 between the intervel [2, b]. First, let's find f(2).
f(2) = 1/(2) = 1/2
So, we have the point (2, 1/2)
At point b, f(b) = 1/b.
Let's plug this into the slope formula:

Now, we just need to solve for b. First, let's multiply both the numerator and denominator by b (to get rid of the annoying fraction in the numerator).

Now, cross multiply.


Solve for b. Factor using the numbers -4 and -2.

Thus, b=4 or b=2.
However, b=2 is not a possible solution since the interval [2,2] means nothing. Thus, b=4.
(-2,2)
i just did my homework with the same question
Answer:
a. 7
Explanation:
A coefficient is the number in front of the variable that is to be multiplied by said variable. Simply identify the coefficient in the term provided to solve the problem.
Well 40 divided by 5 is 8 and you don't have options so I would say 8 loads a day :)
