1) A hardware company's cost, in thousands of dollars, is represented by the function C(x)=0.5x+900 and its revenue, in thousands of dollars, is represented by the function R(x)=4x. Each package of nuts and bolts is represented by x. How much will the company profit if they sell 80000 packages? Round your answer to the nearest dollar, and do not include the dollar sign in your answer.

Answer 1
Answer:

Answer:

Profit = $279,100

Step-by-step explanation:

We know

Profit = Revenue - Cost

Given Cost equation and Revenue equation, we can find profit equation. Shown below:

Profit=Revenue-Cost\nP(x)=R(x)-C(x)\nP(x)=4x-(0.5x+900)\nP(x)=4x-0.5x-900\nP(x)=3.5x-900

Where x, is the number of packages.

The company will profit when selling 80,000 packages is:

P(x)=3.5x-900\nP(80000)=3.5(80000)-900=279,100

Profit = $279,100

Pls explain how to solve this
15-3n=n-1

Answers

First you have to isolate the variable. That means you have to get all the terms with the letter (n) on one side of the equal sign and everything else on the other side. To do this:
First add 3n to both sides and get:
15=4n-1
Now you have to add 1 to both side and get:
16=4n
Now you have to divide both sides by 4.
You get the answer of:
4=n

Simplify the expression x^2+x-2/8x^2+4x/3x^2+10x+8

Answers

Answer:

Step-by-step explanation:

x² + x  - 2 = x² - x +2x -2 = x(x - 1) + 2*(x-1)  = (x-1)(x+2)

8x² + 4x = 4x ( 2x + 1)

3x² + 10x + 8 = 3x² + 6x + 4x + 4*2  =3x  * (x + 2) + 4 * ( x + 2) = (x + 2)(3x + 4)

A plane slices diagonally through a rectangular prism as shown. Which term best describes the cross-section formed by the intersection of the plane and the prism?

Answers

Answer:

Rectangle shaped cross section is formed by intersection of plane and prism.

Step-by-step explanation:

Given: A rectangular Prism.

To find: Shape of Cross Section when a plane intersect the prism diagonally

A plane intersect the Rectangular prism .i.e, Cuboid diagonally which means plane passes from top edge of cuboid to edge on bottom on opposite side.

Figure is attached.

In this way we get a Rectangular shaped Cross section which includes edges of cuboid and diagonals of the side faces.

Therefore, Rectangle shaped cross section is formed by intersection of plane and prism.
