A furniture company is introducing a new line of lounge chairs next quarter. These are the cost and revenue functions, where x represents the number of chairs to be manufactured and sold: R(x) = 1,248x – 8.32x2 C(x) = 36,400 – 83.2x
The profit function for a furniture company introducing a new line of lounge chairs is P(x) =\(-8.32x^2 + 1,248x - 36,400\), where x represents the number of chairs to be manufactured and sold.
The problem provides the revenue function and cost function for a furniture company introducing a new line of lounge chairs. To find the profit function, we need to subtract the cost function from the revenue function.
The revenue function R(x) is given as 1,248x - \(8.32x^2\), where x represents the number of chairs manufactured and sold. This function calculates the total revenue obtained by the company by multiplying the number of chairs sold (x) by the price of each chair (1,248 - 8.32x).
The cost function C(x) is given as 36,400 - 83.2x. This function calculates the total cost incurred by the company to manufacture x chairs, which includes both fixed and variable costs.
To find the profit function for the furniture company, we need to subtract the cost function C(x) from the revenue function R(x):
P(x) = R(x) - C(x) = (1,248x - \(8.32x^2\)) - (36,400 - 83.2x)
Simplifying this expression, we get:
P(x) =\(-8.32x^2\) + 1,248x - 36,400
Therefore, the profit function for the furniture company is P(x) = \(-8.32x^2\) \(+ 1,248x - 36,400\).

A company that manufactures golf balls produces a new type of ball that is supposed to travel significantly farther than the company’s previous golf ball. To determine this, 40 new-style golf balls and 40 original-style golf balls are randomly selected from the company’s production line on a specific day. The balls are then placed in a bag and shaken. A golf pro then selects a ball and hits it. The distance the ball travels is then measured. The bag is shaken again, and the golf pro selects another ball to hit. She continues this procedure until all 80 of the golf balls are hit.
Has the principle of comparison been addressed in this experimental design?
A Yes, because the balls are randomly selected, the distances of the new ball can be compared to the distances of the original ball.
B Yes, because the original ball type is included in this experiment, the distances the different balls travel can be accurately compared.
C No, because a placebo ball was not used, a comparison cannot be made to determine if the new ball travels significantly farther.
D No, because all of the new type of balls are not hit first, the distances they travel cannot be compared to the distances of the original ball.

3 6 9 12 15 18 21 24 27 30 is odd or even numbers?
Answer: Half of them are even and half of them are odd.
Step-by-step explanation:
The even numbers are 6, 12, 18, 24, and 30. An even number is defined as a number that is divisible by 2, meaning it has no remainder when divided by 2. For example, 6 divided by 2 equals 3 with no remainder, so 6 is even.
The odd numbers are 3, 9, 15, 21, and 27. An odd number is defined as a number that is not divisible by 2, meaning it has a remainder of 1 when divided by 2. For example, 9 divided by 2 equals 4 with a remainder of 1, so 9 is odd.
Therefore, out of the given numbers, half of them are even and half of them are odd.

Ty bought a new computer for $499. This brand depreciates at a rate of 12% of the original price per year. The value y of Ty's computer, x years after he purchased it, is found using an equation in the form y = mx + b. What is the approximate value of m?
Answer:
the approximate value of m is -0.12, indicating that the value of Ty's computer decreases by 0.12 (or 12%) each year.
Step-by-step explanation:
o express this depreciation rate as a slope in the equation y = mx + b, we need to determine how much the value changes (the "rise") for each year (the "run").
Since the value decreases by 12% per year, the slope (m) would be -12%. However, we need to express the slope as a decimal, so we divide -12% by 100 to convert it to a decimal:
m = -12% / 100 = -0.12

Answer:
$20.44
Step-by-step explanation:
The average of a set of numbers is defined as:
\(\dfrac{\textrm{sum of values}}{\textrm{number of values}}\)
In this problem, we are shown a table where each row has a coupon value in the left column and the number of that coupon value in the right column (e.g., if we look at the top row, we can see there are 70 coupons each valued at $10).
So, the sum of values in this problem (i.e., the total number of dollars given out by the store in the form of coupons) is defined as the sum of the product of each row.
\(\textrm{sum of values} = (\$10 \times 70) + (\$20 \times 40) + (\$40 \times 20) + (\$60 \times 4) + (\$120 \times 2)\)
\(\textrm{sum of values} = \$700 + \$800 + \$800 + \$240 + \$240\)
\(\textrm{sum of values} = \$2780\)
The number of values in this problem is just the sum of the numbers in the right column (i.e., the number of coupons given out).
\(\textrm{number of values} = 70 + 40 + 20 + 4 + 2\)
\(\textrm{number of values} = 136\)
Finally, to answer the problem, we can plug the two numbers that we just solved for into the formula for the average of a set.
\(\textrm{average savings} = \dfrac{\textrm{value of all tickets}}{\textrm{number of tickets}}\)
\(\textrm{average savings} = \dfrac{\$2780}{136}\)
\(\textrm{average savings} \approx \$20.44\)

Five whole numbers are written in order
4 6 x y
10
The mean and median of the five numbers are the same.
Work out the values of x and y.
Answer:
\(x = 7\) and \(y = 8\)
Step-by-step explanation:
Given
4 6 x y 10
Median = Mean
Required
Find x and y
The mean is calculated as:
\(Mean=\frac{4 + 6 + x + y + 10}{5}\)
Collect Like Terms
\(Mean=\frac{4 + 6 + 10+ x + y }{5}\)
\(Mean=\frac{20+ x + y }{5}\)
The median which is the mid-data is x
i.e.
\(Median = x\)
Median = Mean; so, we have:
\(x=\frac{20+ x + y }{5}\)
Multiply through by 5
\(5 * x=\frac{20+ x + y }{5} * 5\)
\(5 x=20+ x + y\)
Collect Like Terms
\(5 x - x=20+ y\)
\(4x=20+ y\)
Since the numbers are in order, the values of x and y could be any of 7, 8 and 9
Such that:
\(x < y\)
So, we need to test the equation with these values
Let x = 7
So, we have:
\(4x=20+ y\)
\(4 * 7 = 20 + y\)
\(28 = 20 + y\)
\(28 - 20 = y\)
\(8 = y\)
\(y = 8\)
This is true for the equation.
Hence:
\(x = 7\) and \(y = 8\)

5. The lengths are given as follows:
BD = 4.3 cm.BC = 11.5 cm.What are the trigonometric ratios?The three trigonometric ratios are given as follows:
Sine of angle = length of opposite side divided by the length of the hypotenuse.Cosine of angle = length of adjacent side divided by the length of the hypotenuse.Tangent of angle = length of opposite side divided by the length of the opposite side.In the second problem, we have that the side x is opposite to the angle of 52º, while the hypotenuse is of 13, hence the equation to solve for x is given as follows:
sin(52º) = x/13.
In item 3, the Pythagorean Theorem is used to solve for m, as follows:
n² + m² = l².
m² = l² - n²
m = square root (l² - n²).
In item 4, we have that the angle opposite to the leg of length 7 inches is of 62º, hence the hypotenuse is given as follows:
sin(62º) = 7/h
h = 7/sin(62º)
h = 7.9 inches.
The length BD in item 5 is obtained as follows:
cos(30º) = BD/5
BD = 5 x cos (30º)
BD = 4.3 cm.
Then the length BC is calculated as follows:
sin(22º) = 4.3/BC
BC = 4.3/sin(22º)
BC = 11.5 cm.

what function corresponds to the table of inputs and outputs?
The linear equation represented by the table is:

Which function corresponds to the table of inputs and outputs?Here we have a table that represents what seems to be a linear function.
Remember that a general linaer function can be written as:
y = a*x +b
Where a is the slope and b is the y-intercept.
If a line passes through two points (x₁,y₁) and (x₂, y₂), then the slope is:
a = (y₂ - y₁)/(x₂ - x₁)
Using the first two points in the table (3, 11) and (5, 17) we will get the slope:
a = (17 - 11)/(5 - 3)
a = 6/2 = 3
So we can write:
y = 3x + b
We know that when x = 3, y = 11, then:
11 = 3*3 + b
11 = 9 + b
11 - 9 = b
2 = b

Provide your answer below:
The percentage is calculated by dividing the required value by the total value and multiplying it by 100.
106% = 102.82
100% = 97
The original price of the bike is $97.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying it by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
We have,
Amount paid for the bike = $102.82
Tax rate = 6%
This means that,
The original price for the bike = 100%
The amount paid for the bike = 106%
Now,
106% = 102.82
Multiply 100/106 on both sides.
100/106 x 106% = 100/106 x 102.82
100% = $97
