Answer:

Step-by-step explanation:
According to Rolle's Theorem, if f(a) = f(b) in an interval [a, b], then there must exist at least one <em>c</em> within (a, b) such that f'(c) = 0.
We are given that g(5) = g(8) = -9. Then according to Rolle's Theorem, there must be a <em>c</em> in (5, 8) such that g'(c) = 0.
So, differentiate the function. We can take the derivative of both sides with respect to <em>x: </em>

Differentiate:

Let g'(x) = 0:

Solve for <em>x</em>. First, divide everything by negative seven:

Factor:
<h3>

</h3>
Zero Product Property:

Solve for each case. Hence:

Since the first solution is not within our interval, we can ignore it.
Therefore:

I believe it is D. The lowest number on the y-axis is -4, and the highest is 0. -4<=y<=0

Step-by-step explanation:
Find 8% of 7500 (600) and multiply it by 24 (amount of months) then add that to 7500
Answer:
(5 + 3i)(5 − 3i) = 34
Step-by-step explanation:
The multiplication of two identical binomials who have different symbol, can be solved using the factoring case of a difference of squares:

So, in this case:


Remember that 
So: 
We replace on the polynomial:
