A large corporation with monopolistic control in the marketplace has its average daily costs, in dollars, given by 900 + 100x + x2 C = X = 180,000 – 50x dollars. Find the quantity that gives maximum profit

Answers

The quantity that gives maximum profit is 1,750 units.

To find the quantity that gives maximum profit, we first need to determine the profit function.

Profit = Total Revenue - Total Cost

Total Revenue is given by the price (p) times the quantity (q):

TR = pq

Since the corporation has monopolistic control, it can set the price to maximize profit. We can use the demand function

to find the price that will maximize profit:

Q = 180,000 - 50p

Solving for p, we get:

p = 3,600 - 0.02Q

Now we can substitute this into the profit equation:

Profit =[tex](3,600 - 0.02Q)Q - (900 + 100Q + Q^2)[/tex]

Simplifying:

Profit = [tex]-Q^2 + 3,500Q - 900[/tex]

To find the quantity that gives maximum profit, we can take the derivative of the profit function with respect to Q and

set it equal to zero:

[tex]d/dQ (-Q^2 + 3,500Q - 900) = 0[/tex]

-2Q + 3,500 = 0

Q = 1,750

Laura is currently paying off her four-year car financing. when she purchased her car, it had a list price of $19,858. laura traded in her previous car, a good-condition 2000 honda insight, for 85% of the trade-in value listed below, financing the rest of the cost at 9.5% interest, compounded monthly. she also had to pay 9.27% sales tax, a $988 vehicle registration fee, and a $77 documentation fee. however, because laura wants to pay off her loan more quickly, she makes a total payment of $550 every month. how much extra is she paying monthly? round all dollar values to the nearest cent.

Answers

Laura is paying each month:

extra payment = $550 - monthly payment

To calculate how much extra Laura is paying each month, we first need to calculate the total cost of her car financing. Here are the steps:

Calculate the trade-in value of Laura's old car. We don't have the exact value, but we know that she received 85% of the trade-in value listed below, so we can set up an equation:

0.85 * trade-in value = value Laura received

Solving for the trade-in value, we get:

trade-in value = value Laura received / 0.85

Add the trade-in value to the list price of the new car to get the total cost before taxes and fees:

total cost before taxes and fees = $19,858 + trade-in value

Add the sales tax, registration fee, and documentation fee to get the total cost of the car financing:

total cost = (1 + 0.0927) * total cost before taxes and fees + $988 + $77

Calculate the monthly payment using the formula for a loan with monthly compounding:

monthly payment = (principal * monthly interest rate) / (1 - (1 + monthly interest rate)^(-number of months))

We know that Laura is financing the rest of the cost after her trade-in value, so:

principal = total cost - value Laura received

monthly interest rate = 0.095 / 12

number of months = 48 (since it's a four-year financing)

Substituting these values into the formula, we get:

monthly payment = ($19,858 + trade-in value - value Laura received) * 0.007916 / [tex](1 - (1 + 0.007916)^{(-48)})[/tex]

Now that we have the total monthly payment, we can calculate how much extra Laura is paying each month:

extra payment = $550 - monthly payment

Note that this assumes that Laura doesn't have any other fees or interest charges on her car financing, such as late payment fees or penalties for paying off the loan early. If there are any additional fees or charges, the calculation may be different.

A farmer uses a lot of fertilizer to grow his crops. The farmer’s manager thinks fertilizer products from distributor A contain more of the nitrogen that his plants need than distributor B’s fertilizer does. He takes two independent samples of four batches of fertilizer from each distributor and measures the amount of nitrogen in each batch. Fertilizer from distributor A contained 21 pounds per batch and fertilizer from distributor B contained 16 pounds per batch. Suppose the population standard deviation for distributor

Answers

Calculated t-value of 6.93 is greater than the critical value, we reject the null hypothesis and conclude that there is strong evidence that the mean amount of nitrogen in distributor A's fertilizer is significantly greater than the mean amount of nitrogen in distributor B's fertilizer.

Since we do not have the population standard deviation, we will need to use the t-distribution for our hypothesis test. We are interested in testing whether the mean amount of nitrogen in distributor A's fertilizer is significantly greater than the mean amount of nitrogen in distributor B's fertilizer.

Let μA be the true mean amount of nitrogen in distributor A's fertilizer and μB be the true mean amount of nitrogen in distributor B's fertilizer. Our null hypothesis is:

H0: μA - μB ≤ 0

The alternative hypothesis is:

Ha: μA - μB > 0

We will use a one-tailed test with a significance level of 0.05. Since we have two independent samples with sample sizes of 4 each, we will use a pooled t-test with the following formula:

t = ([tex]\bar{X1}[/tex] - [tex]\bar{X2}[/tex] - D) / (sP * √(2/n))

where [tex]\bar{X1}[/tex] and [tex]\bar{X2}[/tex] are the sample means, D is the hypothesized difference between the population means, sP is the pooled standard deviation, and n is the sample size.

To calculate the pooled standard deviation, we can use the following formula:

sP = √(((n1-1)*s1² + (n2-1)*s2²) / (n1+n2-2))

where n1 and n2 are the sample sizes, and s1 and s2 are the sample standard deviations.

Plugging in the given values, we get:

[tex]\bar{X1}[/tex] = 21, [tex]\bar{X2}[/tex] = 16

s1 = s2 = 1.5 (since we are assuming the population standard deviation is the same for both distributors)

n1 = n2 = 4

D = 0 (since the null hypothesis is that there is no difference in the means)

sP = √(((4-1)*1.5² + (4-1)*1.5²) / (4+4-2)) = 1.5

Using these values, we get:

t = (21 - 16 - 0) / (1.5 * √(2/4)) = 6.93

Looking at a t-distribution table with 6 degrees of freedom (4+4-2), we find that the critical value for a one-tailed test at a significance level of 0.05 is approximately 1.943. Since our calculated t-value of 6.93 is greater than the critical value, we reject the null hypothesis and conclude that there is strong evidence that the mean amount of nitrogen in distributor A's fertilizer is significantly greater than the mean amount of nitrogen in distributor B's fertilizer.

Answers

We know that the function (f+ g)(x) = 13x^2 + 8x + 2 and (f+ g)(-2) = 38.

Hi! I'd be happy to help you with your question.

Given the functions f(x) = 9x^2 + 8x + 2 and g(x) = 4x^2, we need to find (f+ g)(x) and (f+ g)(-2).

To find (f+ g)(x), simply add the functions f(x) and g(x) together:

(f+ g)(x) = f(x) + g(x) = (9x^2 + 8x + 2) + (4x^2) = 13x^2 + 8x + 2

Now, we need to find (f+ g)(-2) by substituting -2 for x in the combined function:

(f+ g)(-2) = 13(-2)^2 + 8(-2) + 2 = 13(4) - 16 + 2 = 52 - 14 = 38

So, (f+ g)(x) = 13x^2 + 8x + 2 and (f+ g)(-2) = 38.

Calculate ∑ (-1)^k pi^2k/2k

Answers

To calculate ∑ (-1)^k pi^2k/2k, we can use the power series expansion for the cosine function:

cos(x) = ∑ (-1)^n x^(2n) / (2n)!

We can substitute pi^2 for x in this formula to get:

cos(pi^2) = ∑ (-1)^n (pi^2)^(2n) / (2n)!
= ∑ (-1)^n pi^(4n) / (2n)!

Now we can compare this to the original series we want to evaluate:

∑ (-1)^k pi^2k/2k = ∑ (-1)^n pi^(2n) / (2n)

We notice that the powers of pi in the two series match up, but the coefficients are different. However, we can use the identity cos(pi^2) = (-1)^n to rewrite the series we want to evaluate as:

∑ (-1)^n pi^(2n) / (2n) = ∑ (-1)^n pi^(4n) / (2n)! * (2n) / pi^2n

= pi^2 / 2 * ∑ (-1)^n pi^(4n) / (2n)!

Now we can substitute our expression for cos(pi^2) into this equation to get:

∑ (-1)^k pi^2k/2k = pi^2 / 2 * cos(pi^2)

= pi^2 / 2 * (-1)^n

Therefore, the value of the series is (-1)^n * pi^2 / 2.
To calculate the sum ∑ (-1)^k (pi^2k)/(2k), it is important to recognize that this is an alternating series with a general term given by a_k = (-1)^k (pi^2k)/(2k).

However, the question seems incomplete, as there is no specified range for the sum (i.e., the values of k). If you provide the range of k for which this sum is to be calculated, I would be glad to help you further.

In the addition problem shown, each letter represents a different digit. If GOD=605, what number does MOVED represent?​

Answers

The number does MOVED represent 1110.

How determine  what number does MOVED represent?

Since GOD=605, we know that D=5. We can now substitute this value of D into the addition problem to get:

GOD+ DOG = MOVED

605+ 506 = 1111

Since M cannot be 0 (otherwise it wouldn't be a 4-digit number), we know that M=1.

We can now subtract 1 from both sides of the equation to get:

604+ 506 = 1110

Now we can see that E+4=10, so E=6. We can also see that O+0=0, so O=0. Finally, we can see that G+D=1, so G=6 and D=5.

Therefore, MOVED = 1110.

the life of light bulbs is distributed normally. the standard deviation of the lifetime is 20 hours and the mean lifetime of a bulb is 580 hours. find the probability of a bulb lasting for at most 624 hours. round your answer to four decimal places.

Answers

The probability of a bulb lasting for at most 624 hours is 0.9861, rounded to four decimal places.

The standard deviation of the lifetime is a measure of how spread out the lifetimes are. In other words, it tells us how much the lifetimes of bulbs vary from the mean. In this case, the standard deviation of the lifetime is 20 hours.

Now, let's get to the question at hand. We want to find the probability of a bulb lasting for at most 624 hours. To do this, we need to use the properties of the normal distribution.

First, we need to calculate the z-score, which tells us how many standard deviations a value is from the mean. We can use the formula z = (x - mu) / sigma, where x is the value we are interested in, mu is the mean, and sigma is the standard deviation. In this case, x = 624, mu = 580, and sigma = 20.

Plugging these values into the formula, we get z = (624 - 580) / 20 = 2.2.

Next, we need to find the probability of a bulb lasting for at most 624 hours, which is the same as finding the area under the normal curve to the left of z = 2.2. We can use a standard normal distribution table or a calculator to find this probability.

Using a calculator, we can use the normal cdf function with the values -9999 (a very large negative number) and 2.2 to find the probability. This gives us a probability of 0.9861.

randomly assigns you to a desk. You may be assigned to the same desk more than once. Over the


course of seven days, what is the probability that you are assigned to a desk in the front row


exactly four times?

Answers

The probability of being assigned to a desk in the front row exactly four times over the course of seven days is approximately 0.008, or 0.8%.

There are a total of 16 desks in the classroom, arranged in 4 rows and 4 columns. The probability of being assigned to a desk in the front row is 4/16 = 1/4, since there are 4 desks in the front row.

To calculate the probability of being assigned to a front-row desk exactly 4 times over the course of 7 days, we can use the binomial probability formula:

P(X = k) = (n choose k) * p^k * (1 - p)^(n-k)

where X is the random variable representing the number of times you are assigned to a front-row desk, n is the number of trials (in this case, 7), k is the number of successes (being assigned to a front-row desk), p is the probability of success on each trial (1/4), and (n choose k) represents the number of ways to choose k successes out of n trials, which is given by the binomial coefficient formula:

(n choose k) = n! / (k! * (n-k)!)

where ! represents the factorial function.

Using this formula, we get:

P(X = 4) = (7 choose 4) * (1/4)^4 * (3/4)^3

P(X = 4) = (35) * (1/256) * (27/64)

P(X = 4) ≈ 0.008

Therefore, the probability of being assigned to a desk in the front row exactly four times over the course of seven days is approximately 0.008, or 0.8%.

The average change in temperature per hour during the temperature drop from 48°F to -16°F in Sioux Falls, South Dakota on February 6, 1995, was 8°F per hour.

What was the rate of temperature change per hour during the significant temperature drop in Sioux Falls?

On February 6, 1995, the temperature in Sioux Falls, South Dakota dropped dramatically from 48°F to -16°F in just eight hours. To calculate the average change in temperature per hour, we can use the formula:

Average Change in Temperature per Hour = (Change in Temperature) ÷ (Time)

Using this formula, we can calculate the average change in temperature per hour in Sioux Falls as follows:

Average Change in Temperature per Hour = (48°F - (-16°F)) ÷ 8 hours

Average Change in Temperature per Hour = 64°F ÷ 8 hours

Average Change in Temperature per Hour = 8°F per hour

Therefore, the average change in temperature per hour during that eight-hour period in Sioux Falls, South Dakota was 8°F. This rapid and significant change in temperature was likely due to a strong cold front moving through the area.

If two lines are parallel, they will never intersect. In this case, since the two equations represent two parallel lines, there is no point of intersection between them. Therefore, the system of equations has no solution.

Hence, the correct answer is A. There is no solution to this system of equations.

In summary, the given system of equations cannot be satisfied simultaneously, since the lines represented by the two equations are parallel to each other and hence do not intersect. Therefore, the system of equations has no solution.

Choosing only among rectangle,rhoumbos,square, name all parallelograms that have the following property

Answers

Among rectangles, rhombuses, and squares, all three of these shapes are parallelograms that have specific properties.

A rectangle is a parallelogram with four right angles. Its opposite sides are equal and parallel, and it has diagonals that are equal in length and bisect each other.

A rhombus, on the other hand, is a parallelogram with all four sides being equal in length. Like a rectangle, its opposite sides are parallel, but it does not necessarily have right angles. The diagonals of a rhombus are perpendicular bisectors of each other, meaning they intersect at a 90-degree angle and divide each other into two equal parts.

Finally, a square is a special type of parallelogram that combines the properties of both rectangles and rhombuses. It has four equal sides and four right angles, making it a unique shape. The diagonals of a square are equal in length, bisect each other, and are also perpendicular bisectors.

In conclusion, rectangles, rhombuses, and squares are all parallelograms with distinct properties. Rectangles have right angles and equal opposite sides, rhombuses have equal sides and diagonals that are perpendicular bisectors, and squares possess all the properties of both rectangles and rhombuses.

"Bacteria in a culture can live for an average of two hours with a standard deviation of 15


minutes. How long can we expect at least 75% of the bacteria to live?"

Answers

75% of the bacteria to live for approximately 130.11 minutes


To answer your question, we'll be using the concept of standard deviation and the normal distribution.

Given that the average lifespan of bacteria in a culture is 2 hours (120 minutes) with a standard deviation of 15 minutes, we can expect at least 75% of the bacteria to live for a certain amount of time. Using the normal distribution, we can determine the corresponding z-score for the 75th percentile, which is approximately 0.674.

Now, we can apply the z-score formula:
z = (X - mean) / standard deviation

Rearrange the formula to solve for X (the time at which 75% of the bacteria will live):
X = mean + (z * standard deviation)

Plugging in the given values:
X = 120 + (0.674 * 15) ≈ 130.11 minutes

So, we can expect at least 75% of the bacteria to live for approximately 130.11 minutes.

What is a transformation?

In Mathematics and Geometry, a transformation can be defined as the movement of a point from its initial position to a new location. This ultimately implies that, when a function or object is transformed, all of its points would also be transformed.

In Mathematics and Geometry, a horizontal translation to the right is modeled by this mathematical equation g(x) = f(x - N) while a vertical translation to the positive y-direction (upward) is modeled by this mathematical equation g(x) = f(x) + N.

Where:

N represents an integer.g(x) and f(x) represent functions.

Choose an amount between $50.00 and $60.00 to represent the cost of a meal for a family. Be sure to include dollars and cents.


Part A: If the family has a 15%-off coupon, calculate the new price of the meal. Show all work or explain your steps. (2 points)


Part B: Calculate a 20% tip using the new price. What is the final cost of the meal? Show all work or explain your steps. (2 points)

Answers

Answer:

The price of the meal after the discount was (A)$48.11 and the final price of the meal was (B)$57.73.

Step-by-step explanation:

Let us consider the amount of money $56.60 as the cost of the meal.

So the amount of money is 56 dollars and 60 cents.

A: The family has a 15% off coupon.

Discount = 15% of 56.60=0.15x56.60=8.49

Now we subtract the discount amount from the original amount.

Cost of the meal = 56.60-8.49=48.11

So the final price of the meal for the family is $48.11 or 48 dollars and 11 cents.

B: The family gave a tip of 20%.

Amount of money tipped= 20% of 48.11=0.20 x 48.11=9.622

To get the final amount we add the tip to the discounted price.

The final cost of the meal= 48.11+9.622=57.732=57.73

Therefore the family paid a total of 57 dollars and 73 cents for the final cost of the meal after the discount and tip.

Hope this helps :)

Suppose two types of wire will be used to form the edges of a rectangle. The wire used
for the width costs $2.50 per foot and the wire used for the height costs $4.25 per foot. Express the total cost of building the rectangle out of wire as a function of the with if the
enclosed area must be 500 square feet.

Answers

To start, let's call the width of the rectangle "w" and the height "h". We know that the area must be 500 square feet, so we can write an equation:

w*h = 500

We can solve this equation for h:

h = 500/w

Now we can express the total cost of the wire in terms of w. The cost of the wire for the width is $2.50 per foot, so the cost for that side is:

2.5w

The cost of the wire for the height is $4.25 per foot, so the cost for that side is:

4.25h = 4.25(500/w) = 2125/w

So the total cost of the wire is:

C(w) = 2.5w + 2125/w

This is our final answer expressed in function notation.
Let's denote the width of the rectangle as w and the height as h. We are given that the area of the rectangle must be 500 square feet, so we have:

w * h = 500

Now, we need to find the cost function based on the width. The cost of the wire for the width is $2.50 per foot and for the height is $4.25 per foot. Therefore, the total cost (C) can be expressed as:

C(w) = 2.50 * w + 4.25 * h

We need to express the height (h) in terms of the width (w) using the area equation:

h = 500 / w

Now, we can substitute this expression for h in the cost function:

C(w) = 2.50 * w + 4.25 * (500 / w)

This is the cost function for building the rectangle out of wire as a function of its width, given that the enclosed area must be 500 square feet.

A lean-to is a shelter where the roof slants down to the ground. The length of the roof of one lean-to is 17 feet. The width of the lean-to is 15 feet. How high is the lean-to on its vertical side?

Answers

The height of the lean-to on its vertical side is 8 feet.

What is the height of a lean-to on its vertical side?

To find the height of the lean-to on its vertical side, we need to use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides. In this case, the vertical side is the hypotenuse, and the length and width are the other two sides.

So, we have:

[tex]height^2 = hypotenuse^2 - width^2[/tex]

We know the length of the roof (the hypotenuse) is 17 feet, and the width is 15 feet. So we can plug these values into the equation and solve for the height:

[tex]height^2 = 17^2 - 15^2\\height^2 = 289 - 225\\height^2 = 64\\height = 8[/tex]

Therefore, the height of the lean-to on its vertical side is 8 feet.
