For this case we have to:

x: It is the variable that represents the number of compact discs.

The cost function must be found considering that each disk costs $7.13. So:

C (x) = 7.13x

Thus, to find the total cost of "x" compact discs (in $) we substitute the number of discs in the cost function.

Answer:

C (x) = 7.13x

Helppppp please.. How do I do this?!? please and than you
Harman [31]

Answer:

  -7/3

Step-by-step explanation:

When finding slope from a graph, I always look for places where the graph crosses grid intersections. One of these is the y-intercept, (0, 40).

You have to go quite some distance to find another. It looks to me like the next grid crossing is at (30, -30). At this point, you can do either of two things:

  • find the ratio of grid squares
  • use the slope formula

What you want to calculate is the ratio of the change in vertical height (rise) to the change in horizontal distance (run). If you use grid squares, you need to make sure the grid has the same number of units horizontally as vertically. (Here a grid square is 10 units in each direction, so we're OK on that point.)

We have observed that the line falls 7 grid squares vertically for a change of 3 grid squares to the right. So, the slope using grid squares is ...

  m = rise/run = -7/3

Using the slope formula, we calculate the slope to be ...

  m = (y2 -y1)/(x2 -x1)

  m = (-30 -40)/(30 -0) = -70/30 = -7/3

The slope of the line is -7/3.

A missing piece of a board game, a circular disk, had an area of 100,608.7, the replacement disks are listed using circumference
STALIN [3.7K]

Answer:

1,124.12 mm

Step-by-step explanation:

<u><em>Steps to answering this question : </em></u>

First determine the radius of the circle from the area of the circle

Use the radius determined above to calculate the circumference

Area of a circle = nr²

where r = radius

n = pi = 3.14

100,608.7mm = nr²

to determine the radius, divide both sides of the equation by 3.14

32,040.98726mm = r²

Find the square root  of 32,040.98726mm

√32,040.98726mm

r = 179mm

Circumference of a circle = 2nr

2 x 179 x 3.14 = 1,124.12 mm

What describes the composition of the transformations
kiruha [24]

Answer:

Step-by-step explanation:

A composition of transformations is a combination of two or more transformations, each performed on the previous image. A composition of reflections over parallel lines has the same effect as a translation (twice the distance between the parallel lines)
