Answer:

Step-by-step explanation:

(f - g)(x)

= f(x) - g(x)

= 5x² - 3 - ( x² - 4x - 8) ← distribute parenthesis by - 1

= 5x² - 3 - x² + 4x + 8 ← collect like terms

= (5x² - x² ) + 4x + (- 3 + 8)

= 4x² + 4x + 5

Answer:

The answer is C. (f-g)(x) simplifies to 4x²+4x+5

Does anyone know how to to explain slope in a easy way

Answers

When you are given two points of a line, you can find the slope of the line.

Let's say that the two points we are given is $\sf(x_1,y_1) ~and ~(x_2,y_2)$ , then the slope is:

$\bf{Slope = (y_2-y_1)/(x_2-x_1)$

Another thing to keep in mind:

When you have 0 in the numerator, and a number in the denominator, that means that the slope is 0.
When you have 0 in the denominator, and a number in the numerator, that means that there is no slope, or that the slope is undefined.

The tuition costs, C, for a local community college are modeled by C(h) = 250 + 200h, where h represents the number of credit hours taken. The local state university has tuition costs, S, modeled by the function S(h) = 300 + 180h. How many credit hours will a student have to take for the two tuition costs to be equal? Round the answer to the nearest tenth of an hour. 250 + 200h = 300 + 180h 250 + 200h = 300 + 180h − 180h − 180h 250 + 20h = 300 h = credit hours

Answers

To solve how many credit hours will a student have to take for the two tuition costs to be equal, the two functions should be equated and solve for the number of hours
C (h) = S (h)
250 + 200h = 300 + 180h
200h – 180h = 300 – 250
20h = 50
H = 2.5 credit hours

The required equation is: $\mathbf{150 + 200h = 300 + 180h}$ and the number of credit hours is 7.5

The functions are given as:

$\mathbf{C(h) = 250 + 200h}$

$\mathbf{S(h) = 300 + 180h}$

When the two tuition costs are equal, we have:

$\mathbf{C(h) = S(h)}$

This gives

$\mathbf{150 + 200h = 300 + 180h}$

Collect like terms

$\mathbf{ 200h -180h= 300 -150 }$

$\mathbf{ 20h= 150 }$

Divide both sides by 20

$\mathbf{ h= 7.5 }$

Hence, the required equation is: $\mathbf{150 + 200h = 300 + 180h}$ and the number of credit hours is 7.5

Answer:

A production level that will minimize the average cost of making x items is x=5.

Step-by-step explanation:

Given that

$c(x)=7x^3-70x^2+13,000x$

is the cost of manufacturing x items

To find a production level that will minimize the average cost of making x items:

The average cost per item is $f(x)=(c(x))/(x)$

Now we get $f(x)= 7x^2-70x+13000$

f(x) is continuously differentiable for all x

Here x≥0 since it represents the number of items.,

Put x=0 in $7x^2-70x+13000$

For x=0 the average cost becomes 13000

$f(0)=7(0)^2-70(0)+13000$

$=13000$

∴ f(0)=13000

To find Local extrema :

Differentiating f(x) with respect to x

$f^(\prime) (x)=14x-70=0$

$14x=70$

$x=(70)/(14)$

∴ x=5 gives the minimum average cost .

At x=5 the average cost is

$f(5)=7(5)^2-70(5)+13000$

$=12825$

∴ f(5)=12825 which is smaller than for x=0 is 13000

∴ f(x) is decreasing between 0 and 5 and it is increasing after 5.
