The costs for a new publishing company can be classified as fixed costs, such as rent and insurance, or variable costs, such as materials and labor. Fixed costs are constant, while variable costs change as the number of items produced changes. The graph shows the weekly variable costs based on the number of books produced.
a. If weekly fixed costs are $300, sketch a graph showing total expenses for the week.
b. Find the total cost of producing 75 books in a week.
Answer:
a) As weekly costs are fixed at $300, we simply need to shift the function up 300 units. (the new function is shown in blue on the attached graph).
b) Reading from the (blue) graph, the total cost of producing 75 books in a week is $600.
fixed cost + variable cost = $300 + $300 = $600

one student we wrote the expression 17 * 102 as 17(100+2). then she simplified to get the expression 1700+34.
Answer:
Step-by-step explanation:
One student rewrote the expression 17 * 102 as 17(100 + 2). Then simplified to get the expression 1700 + 34.
a. Are the three expressions equivalent (17 * 102, 17(100 + 2), and 1700 + 34)?
Yes, they are.
Check your answer:
17 * 102 = 1734
17(100 + 2)
17(100) + 17 * 2
1700 + 34 = 1734
1700 + 34 = 1734

A trapezoidal prism undergoes a dilation. The surface area of the pre-image is 35 m². The surface area of the image is 315 m². The height of the pre-image is 5. 8 m. What is the height of the image? Enter your answer as a decimal in the box. M.
The original object is called pre-image, and its dilated version is called image. The height of the image for the considered case is 17.4 m
How does dilation affect length, area, and volume of an object?Suppose a figure (pre image) is dilated (dilated image) by scale factor of k.
So, if a side of the figure is of length L units, and that of its similar figure is of M units, then:
L = k × M
where 'k' will be called as scale factor.
The linear things grow linearly like length, height etc.
The quantities which are squares or multiple of linear things twice grow by square of scale factor. Thus, we need to multiply or divide by k² to get each other corresponding quantity from their similar figures' quantities.
So area of first figure = k² × area of second figure
Similarly,
Volume of first figure = k³ × volume of second figure.
It is because we will need to multiply 3 linear quantities to get volume, which results in k getting multiplied 3 times, thus, cubed.
For this case, we're given that;
Surface area of pre-image = 35 m²Surface area of dilated image = 315 m²Height of pre-image = 5.8 mHeight of dilated image.Let the scale fator of dilation be k.
Then:
So area of pre-image = k² × area of dilated image
Thus, we get:
[tex]35 = k^2 \times 315\\\\k = \sqrt{\dfrac{35}{315}} = 1/3[/tex]
(took positive root as scaling is done by non-negative factors as only magnitude matters mostly)
Thus, we get:
Height of pre-image = (1/3) × Height of dilated image (say h)
[tex]5.8 = (1/3) \times h\\h = 3 \times 5.8 = 17.4 \rm \: m[/tex]
Thus, the original object is called pre-image, and its dilated version is called image. The height of the image for the considered case is 17.4 m

Find the MEAN of the following:
13, 19, 17, 10, 22, 14, 17
Mean: 16
To find the mean, we need to add up all the numbers in the set and then divide by the number of numbers we added.
1. 13 + 19 + 17 + 10 + 22 + 14 + 17 = 112
2. 112 / 7 = 16
3. The mean is 16.
Answer: 16.
Step-by-step explanation: To find the mean of any given data, you need to add all the data. The work is below:
13 + 19 + 17 + 10 + 22 + 14 + 17 = 112.
Now that we've added all the data, we have to divide the data by 7, because that's how many numbers that are in this data. The work is below:
112 / 7 = 16.
Therefore, the mean of this data is 16.

Please help I don't understand because of this depreciation stuff. I want to know which one will be a better buy
So if i'm reading it right, it says the total depreciation will be 13% & 14% after the 5 years. If i'm misunderstanding, let me know and i'll fix my answer because the process will be a bit different
Depreciation means a decrease in something over time. You can think of it like a "__% off" sale if that helps
For the first option, we need to find 13% of 18,000. "Of" always means multiply, so 13%*18,000=2,340
Since we're decreasing, subtract 2,340 from the original cost
18,000-2,340=$15,660
Same process for the second option
14%*22,000=3,080
22,000-3,080=$18,920

A rectangular prism has a total surface area of $56. $ Also, the sum of all the edges of the prism is $60. $ Find the length of the diagonal joining one corner of the prism to the opposite corner
Length of the diagonal of rectangular prism is equals to 13units.
What is rectangular prism?
" Rectangular prism is a three dimensional figure which has six faces in rectangular shape."
Formula used
Total surface area of the rectangular prism = 2(l b + b h +l h)
Sum of all the edges of the prism = 4 (l +b + h)
length of the diagonal of the prism = √l² + b² + h²
l = length of the prism
b = width of the prism
h = height of the prism
According to the question,
Given,
Total surface area of the rectangular prism = 56 units
⇒2(l b + b h +l h) = 56
Sum of all the edges of the prism = 60 units
⇒4(l + b + h) = 60
Divide both the side by 4 we get,
(l + b + h) = 60 / 4
⇒(l + b + h) = 15 ____(1)
Squaring both the side of (1) we get,
(l + b + h)² = (15)²
⇒l² + b² + h² + 2 (l b + b h +l h) = 225
Substitute the value of total surface area to get length of the diagonal,
l² + b² + h² + 56 = 225
⇒l² + b² + h² = 225 - 56
⇒l² + b² + h² = 169
⇒√l² + b² + h² = √169
⇒√l² + b² + h² = 13
Hence, length of the diagonal of rectangular prism is equals to 13units.
