Answer: about 22 minutes
Explanation: its hard to explain but trust me i checked my work
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:

Answer:
1.95
Step-by-step explanation:
hello :
ln (x + 6) – ln (2x – 1) = 1 ...(*)
this expression exist : 2x-1 > 0 and x+6 > 0 means : x> 1/2 and x > -6
hence for : x> 1/2 (*) equivalent to ln((x+6)/(2x-1))= lne.......(1=lne)
(x+6)/(2x-1) = e
x+6 = e(2x-1) means : x+6 = 2ex-e
-x+2ex = e+6
x(2e-1) = e+6
x = (e+6)/(2e-1) =(2.73+6)/(2(2.73)-1) =8.73/4.46 =1.95
