If you see marginal cost increasing in a graph, this implies that; b. the additional cost incurred in producing one more unit of output is decreasing.
What is the interpretation of the marginal cost?
The marginal cost is the change in total production cost that comes from making or producing one additional unit.
When marginal product is rising, the marginal cost of producing another unit of output is declining and when marginal product is falling marginal cost is rising. Thus, Option A and D are not correct.
Option C is wrong because Marginal cost helps to increase efficiency in production.
Thus, option B is the correct answer.

(4) 2}
I need some work or explanation please ASAP
The solution to function f(x) = 4 is 2 1/5.
Given that, f(x) = 5x - 7
Now, function f(x) = 4 implies that
i.e. 5x - 7 = 4
i.e. 5x = 4 + 7
i.e. 5x = 11
i.e. x = 11/5
x =2 1/5
So, option (4) is correct.
The core concept of mathematics' calculus is functions. The unique varieties of relations are the functions. In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.

The function is f(x)= 5x-7. The solution to f(x)=4 is when x is 11/5.
Given that,
The function is f(x)= 5x-7
A function is nothing but in mathematics, a function is a unique arrangement of the inputs (also referred to as the domain) and their outputs (sometimes referred to as the codomain),where there is exactly one output for every input, and the output can be connected to its input.
f(x), where x is the input, is a common way to refer to a function. A function represented as y = f(x).
We have to find the solution to f(x)=4
Take 5x-7 in the place of f(x) because they are equal.
5x-7=4
5x=4+7
5x=11
x=11/5
Therefore, the solution x value is 11/5.

A small publishing company is planning to publish a new book. Let C be the total cost of publishing the book (in dollars). Let N be the number of copies of the book produced. For the first printing, the company can produce up to 200 copies of the book. Suppose that C= 10/N + 800 gives C as a function of N during the first printing. Identify the correct description of the values in both the domain and range of the function. Then, for each, choose the most appropriate set of values.
The domain is the set of all integers lying in the interval [0 , 200] and range is the set of all reals lying in the interval [800 , 2800].
What is a function?
A function defined from A to B, associates each and every element of the set A tò the element of set B. In mathematics, it is represented using the symbol, f : A -> B. Here, set A is called the domain of the function while set B is called the range of a function.
Calculation of domain and range of a given function
The domain is the set of all possible values of x. According to this question, the domain of N lies in the interval [0 , 200] i.e. all the integers lying in the given interval. Only integers are chosen because the number of books cannot be in fraction.
The range is the set of possible costs and lies in the interval [800 , 2800] i.e. all the reals lying in the given interval.
Hence, the domain is the set of all integers lying in the interval [0 , 200] and range is the set of all reals lying in the interval [800 , 2800].

Answer:
Step-by-step explanation:
The Sugar Sweet Company will choose from two companies to transport its sugar to market. The first company charges $5500 to rent trucks plus an additional fee of $200.25 for each ton of sugar. The second company charges $5041 to rent trucks plus an additional fee of $225.75 for each ton of sugar.
The computation shows that the tons of sugar when they'll have same price is 18 tons.
How to compute the value?The first company charges $5500 to rent trucks plus an additional fee of $200.25. Thai will be:
= 5500 + (200.25 × s)
= 5500 + 200.25s
where s = tons of sugar
The second company charges $5041 to rent trucks plus an additional fee of $225.75 for each ton of sugar. This will be:
5041 + 225.75s
Then we will equate both of them. This will be:
5500 + 200.25s = 5041 + 225.75s
5500 - 5041 = 225.75d - 200.25s
459 = 25.5s
s = 459/25.5
s = 18
At 18 tons, they'll have same price.

Consider the integral
[tex]\displaystyle \int_{-\infty}^\infty \frac{5 + 2x^2}{1 + x^2} e^{-x^2} \, dx[/tex]
which is the negative of yours. Bit strange to integrate over [tex](\infty,-\infty)[/tex], but if that's what you actually intended, just multiply the final result by -1. Of course, I've already canceled the superfluous factors of [tex]x^2[/tex].
Expand the integrand into partial fractions.
[tex]\displaystyle \int_{-\infty}^\infty \frac{5 + 2x^2}{1 + x^2} e^{-x^2} \, dx = \int_{-\infty}^\infty \left(2 + \frac3{1+x^2}\right) e^{-x^2} \, dx[/tex]
Recall that for [tex]\alpha>0[/tex],
[tex]\displaystyle \int_{-\infty}^\infty e^{-\alpha x^2} \, dx = \sqrt{\frac\pi\alpha}[/tex]
Now let
[tex]\displaystyle I(a) = \int_{-\infty}^\infty \frac{e^{-ax^2}}{1+x^2} \, dx[/tex]
Together, these give
[tex]\displaystyle \int_{-\infty}^\infty \frac{5 + 2x^2}{1 + x^2} e^{-x^2} \, dx = 2\sqrt\pi + 3I(1)[/tex]
Differentiate [tex]I(a)[/tex] under the integral sign with respect to [tex]a[/tex] to obtain a simple linear differential equation.
[tex]\displaystyle \frac{dI}{da} = -\int_{-\infty}^\infty \frac{x^2 e^{-ax^2}}{1+x^2} \, dx \\\\ ~~~~~~~~ = - \int_{-\infty}^\infty \left(1 - \frac1{1+x^2}\right) e^{-ax^2} \, dx \\\\ ~~~~~~~~ = -\sqrt{\frac\pi a} + I(a)[/tex]
Solve for [tex]I(a)[/tex] with the initial value [tex]I(1) = \sqrt\pi[/tex]. Using an integrating factor,
[tex]\displaystyle \frac{dI}{da} - I(a) = -\sqrt{\frac\pi a} \\\\ e^{-a} \frac{dI}{da} - e^{-a} I(a) = -\sqrt{\frac\pi a}\,e^{-a} \\\\ \frac{d}{da}\left[e^{-a} I(a)\right] = -\sqrt{\frac\pi a}\,e^{-a}[/tex]
By the fundamental theorem of calculus,
[tex]\displaystyle e^{-a} I(a) = e^{-a}I(a)\bigg|_{a=0} - \sqrt\pi \int_0^a \frac{e^{-\xi}}{\sqrt\xi} \, d\xi \\\\ I(a) = \pi e^a - \sqrt\pi \, e^a \int_0^a \frac{e^{-\xi}}{\sqrt\xi} \, d\xi[/tex]
so that
[tex]\displaystyle I(1) = \pi e - \sqrt\pi\,e \int_0^1 \frac{e^{-\xi}}{\sqrt\xi} \, d\xi[/tex]
Substitute [tex]t=\sqrt\xi[/tex].
[tex]\displaystyle I(1) = \pi e - 2\sqrt\pi\,e \int_0^1 e^{-t^2} \, dt[/tex]
Recall the error function,
[tex]\mathrm{erf}(x) = \displaystyle \frac2{\sqrt\pi} \int_0^x e^{-t^2} \, dt[/tex]
which we can use to write
[tex]I(1) = \pi e - 2\sqrt\pi e \cdot \dfrac{\sqrt\pi}2\,\mathrm{erf}(1) = \pi e - \pi e \,\mathrm{erf}(1)[/tex]
Finally, we arrive at
[tex]\displaystyle \int_{-\infty}^\infty \frac{5 + 2x^2}{1 + x^2} e^{-x^2} \, dx = \boxed{2\sqrt\pi + 3\pi e - 3\pi e \, \mathrm{erf}(1)}[/tex]

f(x) = cube root 2x
g(x) = 2x + 1
Find (f/g) (X) Include any restrictions on the domain
Answer:
B.
Step-by-step explanation:
any arithmetic operation with functions just means to do this operation with the functional expressions.
f/g is really just the expression of f divided by the expression of g.
so, this results in a fraction with the denominator (bottom part) = 2x + 1
as you know, a division by 0 is not a valid operation, and therefore we have to forbid any value for x that would create a 0 in the denominator.
so, for what x do we get
2x + 1 = 0
2x = -1
x = -1/2
therefore, we have to exclude x = -1/2.

Answer:
C. Multiply by 5, then subtract 7.
Step-by-step explanation:
You want to know the two steps required to solve this 2-step linear equation.
SolutionThe variable x has 7 added to it, and the sum is divided by 5. To find the value of x, we must undo these operations in reverse order.
To undo division by 5, we must multiply by 5.
Then, to undo the addition of 7, we must subtract 7.
Here is the "work":
[tex]\dfrac{x+7}{5}=10\qquad\text{given}\\\\x+7 = 50\qquad\text{multiply both sides by 5}\\\\x=43\qquad\text{subtract 7 from both sides}[/tex]
The operations in order of use are ...
Multiply both sides by 5 first, then subtract 7 from both sides.

The length of a rectangle is twice its width.
If the perimeter of the rectangle is 36 m, find its area
Answer:
length= 12 width=6
Step-by-step explanation:
when adding perimeter you add the length and width twice each so divide 36 by two and get 18
if the length is twice the width then you could make the equation w+2w=18
by adding like terms you get 3w=18
to get n by itself you divide 18 by 3 and get w=6
if the width is 6 and the length is twice that then the length is 12
Answer:
A=72
Step-by-step explanation:
The length of a rectangle is TWICE it's width meaning 2 times. (Note that L= length, W=width, and A=Area)
L=2w
4w+2w=36
6w=36 <- ( 6 is width)
then
2x6=12
Then
12x6=72
So the area of the rectangle is 72.
