An expression for the profit of the company is 26x - 0.0002x^2 - 120,000.

To find the expression for the profit of a company, we need to subtract the cost from the revenue.

The cost of the company is given by the expression 14x + 120,000, where x represents the quantity of the product being produced or sold.

The revenue of the company is given by the expression 40x - 0.0002x^2, where x represents the quantity of the product being produced or sold.

To find the profit, we subtract the cost from the revenue:

Profit = Revenue - Cost

Profit = (40x - 0.0002x^2) - (14x + 120,000)

To simplify the expression, we distribute the negative sign:

Profit = 40x - 0.0002x^2 - 14x - 120,000

Combining like terms:

Profit = (40x - 14x) - 0.0002x^2 - 120,000

Simplifying further:

Profit = 26x - 0.0002x^2 - 120,000

Therefore, an expression for the profit of the company is 26x - 0.0002x^2 - 120,000.

Final answer:

The profit of a company is the difference between its total revenue and costs, and can be calculated using the formula P = R - (14x - 0.0002x²), where P is profit, R is revenue, and x is the number of units.

Explanation:

To calculate the expression for the profit of the company, we need to find the difference between the total revenue and the total cost.

Given the cost can be modeled by 14x - 0.0002x2, and assuming the revenue is R, the profit P can be represented as:

P = R - (14x - 0.0002x²)

If we are given a specific value for the revenue, we would substitute it in place of R to find an explicit expression for P. For instance, if the revenue is $200,000, the profit formula would be:

P = $200,000 - (14x - 0.0002x²)

It's important to note that the profit decreases as the cost increases, and when costs exceed revenue, the company experiences a loss.

Step-by-step explanation:

Given:

AB is the diameter of a circle.

m∠CAB = 26°

To find:

The measure of m∠CBA.

Solution:

Angle formed in the diameter of a circle is always 90°.

⇒ m∠ACB = 90°

In triangle ACB,

Sum of the angles in the triangle = 180°

m∠CAB + m∠ACB + m∠CBA = 180°

26° + 90° + m∠CBA = 180°

116° + m∠CBA = 180°

Subtract 116° from both sides.

116° + m∠CBA - 116° = 180° - 116°

m∠CBA = 64°

The measure of m∠CBA is 64°.

The size of angle CBA is 128 degrees.

To find the size of CBA, we can use the fact that angles in a triangle add up to 180 degrees. Since AB is a diameter, it divides the circle into two semicircles, and angle CAB is an inscribed angle that is half the measure of the central angle.

Therefore, m(CAB) = 26 degrees, and m(CBO) = 2 * 26 = 52 degrees. Since angle CBA is an exterior angle of triangle CBO, it is equal to the sum of the remote interior angles, which is 180 - 52 = 128 degrees.

So, the size of CBA is 128 degrees. The answer is option D. 74.

Step-by-step explanation:

you needed to expand letter a. and simplify letter b.

To solve the system of equations y=x^2-3x+2 and y=-9x-3, set them equal and solve the resulting quadratic equation using the quadratic formula to obtain the solutions for x; then substitute back to find y.

To solve the system of equations given by y = x2 - 3x + 2 and y = -9x - 3, we must find the values of x and y that satisfy both equations simultaneously. Since both expressions are equal to y, we can set them equal to each other to find the x-values that satisfy both equations:

x2 - 3x + 2 = -9x - 3

Rearrange the equation by adding 9x and 3 to both sides:

x2 + 6x - 1 = 0

This is a quadratic equation, which we can solve by factoring, completing the square, or using the quadratic formula. In this case, factoring is not straightforward, so we may opt for the quadratic formula:

x = (-b ± √(b2 - 4ac)) / (2a)

Here, a = 1, b = 6, and c = -1. Plugging these into the quadratic formula gives us:

x = (-6 ± √(36 + 4)) / 2

x = (-6 ± √(40)) / 2

x = (-6 ± 2√(10)) / 2

x = -3 ± √(10)

So the solutions for x are x = -3 + √(10) and x = -3 - √(10). To find the corresponding y-values, substitute these x-values back into either of the original equations.

The solution to the system of equations is:
(x, y) = (-1, 6) and (-5, 42)

To solve the system of equations:

1. Substitute the expression for y from the second equation into the first equation. This gives us:

x^2 - 3x + 2 = -9x - 3

2. Rearrange the equation to bring all terms to one side, setting the equation equal to zero:

x^2 - 3x + 9x + 2 + 3 = 0

x^2 + 6x + 5 = 0

3. Factor the quadratic equation:

(x + 1)(x + 5) = 0

4. Apply the zero product property to find the values of x that satisfy the equation:

x + 1 = 0 or x + 5 = 0

x = -1 or x = -5

5. Substitute these values of x back into either equation to find the corresponding values of y. Let's use the second equation:

For x = -1:
y = -9(-1) - 3 = 9 - 3 = 6

For x = -5:
y = -9(-5) - 3 = 45 - 3 = 42

Therefore, the solution to the system of equations is:
(x, y) = (-1, 6) and (-5, 42)

Then divide 346.88 by 37.5

You get 9.25=h

Rodrick earned $9.25 per hour.

Rodrick earned approximately $9.25 per hour.

To find out how much Rodrick earns per hour, we need to divide his total pay by the number of hours worked. In this case, Rodrick worked for 37.5 hours and earned $346.88. So, to find his earnings per hour, we divide $346.88 by 37.5:

Earnings per hour = Total pay / Number of hours

Earnings per hour = $346.88 / 37.5

Earnings per hour ≈ $9.25

Therefore, Rodrick earned approximately $9.25 per hour.

2. 12.3 units

3. 23.3 units

4. 10.9 units

Step-by-step explanation:

1. We have the opposite and adjacent sides here for angle 31 degrees. So we need to use tangent, which is opposite / adjacent:

[tex]tan(31)=16/x[/tex]

[tex]x=16/(tan(31))[/tex] ≈ 26.6 units

2. We have the opposite and hypotenuse sides here for angle 43 degrees. So we need to use sine, which is opposite / hypotenuse:

[tex]sin(43)=x/18[/tex]

[tex]x=18*sin(43)[/tex] ≈ 12.3 units

3. We have the adjacent and hypotenuse sides here for angle 53 degrees. So we need to use cosine, which is adjacent / hypotenuse:

[tex]cos(53)=14/x[/tex]

[tex]x=14/(cos(53))[/tex] ≈ 23.3 units

4. We have the adjacent and hypotenuse sides here for angle 33 degrees. So we need to use cosine, which is adjacent / hypotenuse:

[tex]cos(33)=x/13[/tex]

[tex]x=13*cos(33)[/tex] ≈ 10.9 units

To find the probability that the mean benefit for a random sample of 25 patients is less than $3920, we calculate the z-score and use the z-table to find the probability. The probability is approximately 0.0749, or 7.49%.
To find the probability that the mean benefit for a random sample of 25 patients is more than $4230, we follow the same steps and find that the probability is approximately 0.0179, or 1.79%.

To find the probability that the mean benefit for a random sample of 25 patients is less than $3920, we need to use the standard deviation and the sample size. The formula we'll use is:

Z = (X - μ) / (σ / sqrt(n))

Where Z is the z-score, X is the value we're interested in, μ is the mean, σ is the standard deviation, and n is the sample size.

Z = (3920 - 4064) / (460 / sqrt(25))

Z = -1.44

P(X < 3920) = P(Z < -1.44)

Z = (4230 - 4064) / (460 / sqrt(25))

Z = 2.13

P(X > 4230) = P(Z > 2.13)

Using the z-table, we find that the probability is approximately 0.0179, or 1.79%.

The probable question may be:

Find the probability that the mean benefit for a random sample of 25 patients is more than $4230

P (X> 4230) =

Average yearly Medicare hospital insurance benefits below $4500: z-score ≈ 0.95, probability ≈ 0.8289. About 82.89% benefits fall below this threshold.

let's break down the steps to solve this problem:

Given:

- Average yearly Medicare hospital insurance benefit [tex](\( \mu \))[/tex] = $4064

- Standard deviation[tex](\( \sigma \))[/tex] = $460

We are asked to find the probability of Medicare hospital insurance benefits being below a certain value, which requires calculating the z-score.

The z-score formula is given by:

[tex]\[ z = \frac{{X - \mu}}{{\sigma}} \][/tex]

Where:

- ( X ) is the value we want to find the probability for,

[tex]- \( \mu \)[/tex] is the mean,

[tex]- \( \sigma \)[/tex] is the standard deviation.

Let's say we want to find the probability for Medicare hospital insurance benefits below $4500. Substituting the values into the formula:

[tex]\[ z = \frac{{4500 - 4064}}{{460}} \][/tex]

[tex]\[ z = \frac{{436}}{{460}} \][/tex]

[tex]\[ z \approx 0.95 \][/tex]

Now, we need to find the probability corresponding to the z-score we calculated. We can use a standard normal distribution table or a calculator for this purpose. The z-score of 0.95 corresponds to a probability of approximately 0.8289.

This means that approximately 82.89% of Medicare hospital insurance benefits are below $4500.

The probability of Medicare hospital insurance benefits being below $4500 is approximately 0.8289 or 82.89%.

Answer:

hunter

Step-by-step explanation:

Final answer:

Hunter is correct that the hypotenuse of a right triangle acts as the diameter of its circumcircle, with the circumcenter located at the midpoint of the hypotenuse.

Explanation:

When constructing a circumcircle of a right triangle, Hunter's assertion is correct. According to a well-known theorem, the hypotenuse of a right triangle will be the diameter of the circumcircle that can be drawn around the triangle. This is because the center of the circumcircle, known as the circumcenter, is equidistant from all vertices of the triangle, and for a right triangle, this point is the midpoint of the hypotenuse.

Since the circumcenter is the midpoint of the hypotenuse, and the hypotenuse is the longest side of a right triangle, it will also serve as the diameter of the circumcircle. The radius of the circle, therefore, extends from this midpoint to any of the triangle’s vertices. Daniel's statement that the circumcenter would be located inside the triangle is incorrect for a right triangle, though it might be true for acute or obtuse triangles.

To calculate the area of Spencer's 7x7 quilt, each square patch measuring 1 3/4 inches is calculated for area (3.0625 sq. in.) and then multiplied by the total number of patches (49), resulting in a total quilt area of 150.0625 square inches.

Spencer made a quilt for his cousin's doll with a 7x7 array of square patches. To find the area of the whole quilt, we need to calculate the area of one patch and then multiply by the total number of patches. The length of each patch is 1 3/4 inches, which can also be represented as 1.75 inches.

First, we find the area of one patch:

Since there are 49 patches in total (7 patches per row × 7 rows), we then find the total area:

Therefore, the area of Spencer's quilt is 150.0625 square inches.

Final answer:

The area of Spencer's quilt is 150.0625 square inches.

Explanation:

Spencer made a quilt for his cousin's doll that had a 7x7 array of square patches, each measuring 1 3/4 inches in length. To find the area of the quilt, you would calculate the area of one patch and then multiply it by the total number of patches in the quilt.

First, convert the inches to a decimal to make the calculation easier:

Area of one square patch = length × width

Since the patches are square, the length and width are the same:

Area of one patch = 1.75 inches × 1.75 inches = 3.0625 square inches

To find the total area of the quilt:

Total area of quilt = area of one patch × number of patches

There are 7 rows and 7 columns in the quilt:

Total patches = 7 × 7 = 49

Total area of quilt = 3.0625 square inches × 49 = 150.0625 square inches

Therefore, the area of the whole quilt is 150.0625 square inches.

Answer:

Therefore I would earn $532,761 more on the first investment than in the second investment.

Step-by-step explanation:

The formula of compound interest

[tex]A=P(1+r)^n[/tex]

Compound interest [tex]I=A-P[/tex]

A= Amount after n years

P= Principal

r=Rate of interest

n= Number of years

First investment,

P₁=$22,000, r=12%=0.12 and n=30 years

[tex]A_1= 22,000(1+0.12)^{30}[/tex]

    =659,118.28

   ≈$659,118

[tex]I_1[/tex]= [tex]A_1[/tex]-P₁

  =$(659,118-22,000)

 =$637,118

Second investment,

P₂=$22,000, r=6%=0.06 and n=30 years

[tex]A_1= 22,000(1+0.06)^{30}[/tex]

    =126,356.81

   ≈$126,357

[tex]I_2[/tex]= [tex]A_2[/tex]-P₂

  =$(126,357-22,000)

  =$104357

[tex]I_1-I_2[/tex]

=$(637,118-104,357)

=$532,761

Therefore I would earn $532,761 more on the first investment than in the second investment.
