The equation Monique, Clarence, Jose and Quincy linear graph is y = (-1/2)x, y = (1/2)x, y = 1.5x + 1 and y = -1.5x - 1 respectively
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
The slope intercept form of a line is:
y = mx + b
where m is the slope and b is the y intercept
Monique graph passes through (0, 0) and (2, -1). Hence:
y - 0 = [(-1 - 0)/(2 - 0)](x - 0)
y = (-1/2)x
Clarence graph passes through (0, 0) and (2, 1). Hence:
y - 0 = [(1 - 0)/(2 - 0)](x - 0)
y = (1/2)x
Jose graph passes through (0, 1) and (-2, -2). Hence:
y - 1 = [(-2 - 1)/(-2 - 0)](x - 0)
y = 1.5x + 1
Quincy graph passes through (0, -1) and (-2, 2). Hence:
y - (-1) = [(2 - (-1))/(-2 - 0)](x - 0)
y = -1.5x - 1

For the required value of the given complex numbers z₁z₂ = 32(cos 255° + isin 255°).
What are complex numbers?Complex numbers are those that expand on the idea of real numbers by incorporating an illogical element.
The formula for a complex number is "a + bi," where "a" and "b" are real numbers and "i" is the imaginary unit, which is equal to the square root of -1.
"A" stands for the complex number's real component, and "b" stands for the imaginary component.
We multiply the magnitudes of two complex numbers and add their arguments to determine their product.
Let's compute z₁z₂ with the supplied values.
Given:
z₁ = 8(cos 45° + isin 45°)
z₂ = 4(cos 210° + isin 210°)
We add the arguments and multiply the magnitudes to find z₁z₂:
Magnitude of z₁ = 8
Magnitude of z₂ = 4
Argument of z₁ = 45°
Argument of z₂ = 210°
Now, let's calculate z₁z₂:
Magnitude of z₁z₂ = (Magnitude of z₁) × (Magnitude of z₂) = 8 × 4 = 32
Argument of z₁z₂ = (Argument of z₁) + (Argument of z₂) = 45° + 210° = 255°

The width of the enlargement would be 34.2857 cm.
What is the difference between length and width?The distance separating an object's ends is its length. The longest dimension is this one. The width of an object is the separation between its two sides. The shortest dimension is this one.
Initial dimension of shorter side = 10 cm
Initial dimension of longer side = 7 cm
Final dimension of shorter side = 24
Final dimension of longer side = x cm
The enlargement always ensure the aspect ratio = longer side / shorter side

8639 is the value of 75 U.S. dollars in Japanese yen.
Why is Japanese money called yen?The term "yen," which refers to Chinese round coins, dates back in time (yuan). The yen was first coined in 1869, following the Meiji Restoration, and was formally recognised as the fundamental unit in the 1871 monetary reform.
"Yen" is Japanese for "circle" or "round thing." With the "New Currency Act" of 1871, the Meiji government formally adopted this currency in an effort to stabilise the nation's monetary position at the time.
The difference between US and Japanese interest rates has been a major factor in the decline of the yen. In an effort to combat the growing cost of living, the US Federal Reserve has aggressively increased its key interest rate from 0.25% to 3.25% since March.
As we see from the table that,
1 U.S dollar = 115.19 Japanese Yen

The area of the rectangular piece of land owned by the rancher is:

The area of a rectangle is a measure of the size of the rectangular space it encloses.
It is calculated by multiplying the length and the width of the rectangle. In this case, the length of the rectangular piece of land owned by the rancher is 5.4 miles and the width is 2.5 miles. To find the area, we multiply these two values.
The formula for finding the area of a rectangle is:
Area = Length * WidthSubstituting the values of length and width into the formula:
Area = 5.4 miles * 2.5 miles = 13.5 square milesSo the area of the rectangular piece of land owned by the rancher is 13.5. This means that if we divide the land into unit squares of 1 square mile each, we would have 13.5 such unit squares.

1. Assuming a linear relationship between the price per rug and the number of rugs sold, find the demand function p=????(????).
2. Angelita paid the other owner $80 per rug for the collection. She calculates fixed costs by taking the same percentage of her average monthly costs to run the store as the percentage of display space needed by the product in question. Her average monthly cost is $3000 and her total amount of display space is 1200 square feet. The rug display uses 120 square feet of display space. Find the cost function p=????(????).
3. Find the revenue function for Angelita’s rugs. State the domain of the revenue function. How many rugs does Angelita need to sell for maximum revenue?
4. Find the profit function for Angelita’s rugs. State the domain of the profit function. How many rugs does Angelita need to sell for maximum profit? What is the maximum profit?
5. Graph the cost and revenue functions on the same graph. Determine the break-even point and interpret its meaning in the context of this problem. How many rugs should be sold in order for Angelita to make money?
Angelita needs to sell at least 32 rugs to make money on her rugs.
The demand function for Angelita's rugs is p=150x-7000, which represents the linear relationship between the price per rug and the number of rugs sold. The cost function for the rugs is p=80x+2400, which is calculated by taking the same percentage of her average monthly costs to run the store as the percentage of display space needed by the product in question, which is 120 square feet of the total 1200. The revenue function for the rugs is p=150x-7000+220x, and the domain of this function is all real numbers. The maximum revenue is achieved when 40 rugs are sold, at $8800. The profit function for the rugs is p=150x-7000+220x-80x-2400, and the domain of this function is all real numbers. The maximum profit is achieved when 37 rugs are sold, at $4940.

What is algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
Number of copies of a popular CD left to be sold in the store = 20
According to question, this is between 15 and 1.5% of the original number of copies of the CD in the store.
Let the original number of copies of the CD be 'x'.
Now, 20 is equal to 1% of the original number of copies of the CD,
1% of x = 20
1/100 of x= 20
x= 2000
Or if 15 is equal to 1.5% of the original number
1.25% of x= 20
1.25/100 x = 20
x = 1600
Hence, the CDs is between 1000 and 1500.

20 inches
Step-by-step explanation:
Area of a triangle = 1/2 × breadth × height
Therefore,
