Y=y coordinate (2in this case)
x=x coordinate (-2 in this case)
m=slope (-2 in this case)
b= y int. (we dont know the number because it doesn’t label it so we just put the letter and you can solve for b if the question tells you so)

so the answer is
y=mx+b (slope int. form)
2=-2(-2)+b

The cost of producing x hundred items is given by the equation C(x) = x2 – 3x + 7 and the revenue generated from sales of x hund

Goryan [66]

Answer:

At x = 2 and 10.

Step-by-step explanation:

Given : The cost of producing x hundred items is given by the equation $C(x) = x^2-3x + 7$

The revenue generated from sales of x hundred units is given by the equation $R(x) = -x^2 + 21x-33$

To Find :What values of x will the company break even?

Solution:

Cost function : $C(x) = x^2-3x + 7$

Revenue function : $R(x) = -x^2 + 21x-33$

Now to find the company break even :

$-x^2 + 21x-33= x^2-3x + 7$

$24x= 2x^2+40$

$12x= x^2+20$

$x^2-12x+20=0$

$x^2-10x-2x+20=0$

$x(x-10)-2(x-10)=0$

$(x-2)(x-10)=0$

So, x = 2,10

Hence the company break even at x = 2 and 10.

What is the sum of areas of the faces on a rectangular prism called

stepladder [879]

Answer:

The surface area of the rectangular prism.

Step-by-step explanation:

The formula for the surface area of a rectangular prism is SA = 2 (wl + hl + hw), which actually represents the areas of each of the faces.

SA = 2wl + 2hl + 2hw

We see that the SA is the sum of the areas of the faces on a rectangular prism. Look at a picture of a rectangular prism if you have trouble understanding this.

In order to estimate the mean amount of time computer users spend on the internet each month, how many computer users must be s

levacccp [35]

Answer:

1877 computer users

Step-by-step explanation:

We have that for 95% of confident, the value of z has a value of 1.96 (attached table about it), they also mention the margin of error (E) that is 10 and finally the standard deviation (sd) that has a value of 221.

We apply the following formula:

n = [z * sd / E] ^ 2

replacing:

n = [1.96 * 221/10] ^ 2

n = 1876.27

that is, the minimum sample size is 1877
