Answer:
The value of c = -0.5∈ (-1,0)
Step-by-step explanation:
<u>Step(i)</u>:-
Given function f(x) = 4x² +4x -3 on the interval [-1 ,0]
<u> Mean Value theorem</u>
Let 'f' be continuous on [a ,b] and differentiable on (a ,b). The there exists a Point 'c' in (a ,b) such that
![f^{l} (c) = \frac{f(b) -f(a)}{b-a}](https://tex.z-dn.net/?f=f%5E%7Bl%7D%20%28c%29%20%20%3D%20%5Cfrac%7Bf%28b%29%20-f%28a%29%7D%7Bb-a%7D)
<u>Step(ii):</u>-
Given f(x) = 4x² +4x -3 …(i)
Differentiating equation (i) with respective to 'x'
f¹(x) = 4(2x) +4(1) = 8x+4
<u>Step(iii)</u>:-
By using mean value theorem
![f^{l} (c) = \frac{f(0) -f(-1)}{0-(-1)}](https://tex.z-dn.net/?f=f%5E%7Bl%7D%20%28c%29%20%20%3D%20%5Cfrac%7Bf%280%29%20-f%28-1%29%7D%7B0-%28-1%29%7D)
![8c+4 = \frac{-3-(4(-1)^2+4(-1)-3)}{0-(-1)}](https://tex.z-dn.net/?f=8c%2B4%20%3D%20%5Cfrac%7B-3-%284%28-1%29%5E2%2B4%28-1%29-3%29%7D%7B0-%28-1%29%7D)
8c+4 = -3-(-3)
8c+4 = 0
8c = -4
![c = \frac{-4}{8} = \frac{-1}{2} = -0.5](https://tex.z-dn.net/?f=c%20%3D%20%5Cfrac%7B-4%7D%7B8%7D%20%3D%20%5Cfrac%7B-1%7D%7B2%7D%20%3D%20-0.5)
c ∈ (-1,0)
<u>Conclusion</u>:-
The value of c = -0.5∈ (-1,0)

Find where the equation is undefined ( when the denominator is equal to 0.
Since they say x = 5, replace x in the equation see which ones equal o:
5-5 = 0
So we know the denominator has to be (x-5), this now narrows it down to the first two answers.
To find the horizontal asymptote, we need to look at an equation for a rational function: R(x) = ax^n / bx^m, where n is the degree of the numerator and m is the degree of the denominator.
In the equations given neither the numerator or denominators have an exponent ( neither are raised to a power)
so the degrees would be equal.
Since they are equal the horizontal asymptote is the y-intercept, which is given as -2.
This makes the first choice the correct answer.
The work done by the gas when the gas expands will be 567.65 ft-lb.
<h3>What is the work done for an isothermal process?</h3>
The Pressure is inversely proportional to the volume.
Let the initial pressure and initial volume be P₁ and V₁, and the final volume be V₂.
Then the work done by the gas will be
WD = P₁ V₁ ln (V₂ / V₁)
A quantity of the gas with an initial volume of 2 cubic feet and an initial pressure of 700 pounds per square foot.
The gas expands to a volume of 3 cubic feet.
Then the work done by the gas will be
WD = 700 x 2 x ln (3/2)
WD = 1400 x 0.405
WD = 567.65 ft-lb
The work done by the gas when the gas expands will be 567.65 ft-lb.

Answer: depth = 5 ft
width = 10 ft
length = 40 ft
Step-by-step explanation:
d = depth
width = d + 5
length = d + 36
Volume = length x width x depth = 2000 cf
d(d+35)(d+5) = 2000
d(
+ 40d + 175) = 2000
d^3 + 40d^2 + 175d = 2000
rewrite in standard cubic polynomial form : ax3 + bx2 + cx + d = 0
d^3 + 40(d^2) + 175d - 2000 = 0
Find the roots of the cubic polynomial:
factors of 2000 are 1, 5, 10 15, 20, etc.
Try the factor 5 first by plugging it in the equation:
5^3 + 40(5^2) + 175(5) - 2000 = 0
Lucky break! No need to find the other roots because they will be negative, and you can't have a negative value for a pool depth.
So, depth = 5 ft
width = 5 + 5 = 10 ft
length = 5 + 35 = 40 ft
