The firm should produce good  x₁ = 4 and x₂ = 8 to minimize cost of C = x₁² + x₂² .

What is Lagrange multipliers ?

Lagrange multipliers is a method used in optimization problems to find the maximum or minimum value of a function subject to one or more constraints. The method involves introducing a Lagrange multiplier, which is a scalar variable, to the objective function and the constraint(s). This forms the Lagrangian function, which is then optimized with respect to the original variables and the Lagrange multiplier.

To minimize the cost C = x₁² + x₂²

We can use the method of Lagrange multipliers to solve this problem. Let's define the Lagrangian function L as:

L(x₁, x₂, λ) = x₁²+ x₂² + λ(400 - 5x₁²- 8x₁x₂ - 15x₂²)

Taking partial derivatives of L with respect to x₁, x₂, and λ, we get:

∂L/∂x₁ = 2x₁ - 10λx₁ - 8λx₂ = 0

∂L/∂x₂ = 2x₂ - 30λx₂ - 8λx₁ = 0

∂L/∂λ = 400 - 5x₁² - 8x₁x₂ - 15x₂² = 0

Solving these equations simultaneously, we get:

x₁ = 4

x₂ = 8

λ = 1/20

Hence, the firm should produce a combination of x₁ = 4 and x₂ = 8 to minimize the cost of C = x₁² + x₂² while satisfying the production quota of 400.

Their realized income must be $567,000 per year to make the monthly payments on the mortgage.

The average interest rate on a 30-year fixed mortgage as of today, March 9, 2023, is 7.13%, up 7 basis points from one week ago. The average 30-year fixed refinancing interest rate is currently 7.12%, which is a decrease of 2 basis points over the previous week.

We must apply the following calculation to compute the amount of money needed each month to pay the mortgage:

Payment each month is (P * r) / (1 - (1 + r)(-n))

where:

P is the principal sum (the amount of the house minus the down payment)

r is the ongoing interest rate (annual interest rate divided by 12)

n is the overall number of payments (number of years multiplied by 12)

The major sum, as far as we are aware, is:

P = $187,500 - (20% * $187,500) = $150,000

The monthly interest rate is as follows because we also know that the interest rate is 4.65%:

r = 0.0465 / 12 = 0.003875

Finding the total number of payments is our last step. The number of months it will take to pay off the mortgage may be calculated using the knowledge that they will be paying $1,575 per month:

$1,575 = ($150,000 * 0.003875) / (1 - (1 + 0.003875)^(-n))

This equation is simplified, and the result is:

1 - (1 + 0.003875)^(-n) = ($150,000 * 0.003875) / $1,575

(1 + 0.003875)^(-n) = 1 - (($150,000 * 0.003875) / $1,575)

(-n) * log(1 + 0.003875) = log(1 - (($150,000 * 0.003875) / $1,575))

n = log(1 - (($150,000 * 0.003875) / $1,575)) / log(1 + 0.003875)

Calculating n, we discover that it roughly corresponds to 360 months (or 30 years).

Their realised income must therefore be:

Realized income is $1,575 multiplied by 12 months in a year for 30 years, or $567,000 annually.

Their realised income must be $567,000 annually in order to cover the mortgage payments.

"From days 3 to 5, the high temperature changed by an average of almost 4 degrees per day," is the appropriate answer.

We can determine the average rate of change from day 3 to day 5 by splitting the difference in high temperature between those two days by the distance between them (which is 2), or 2.

The highest temps on Day 3 was 85°F.

The highest temperature on Day 5 was 77°F.

Extreme temperature variation: 77°F to 85°F equals -8°F

Between day three and day five, there are two days.

(Change in maximum temperature) / (number of days) yields an average rate of change of -8°F / 2°F per day.

This leads to the conclusion that the right response is "The high temperature changed by an average of 4 degrees per day from day 3 to day 5".

Answer:

To make the piano player's practice seem consistent, adjust the Y-axis scale, use a line graph, and add a trend line or moving average.

Step-by-step explanation:

To adjust the graph to make it seem like the piano player is pretty consistent in practicing, we can make the following changes:

Adjust the scale of the Y-axis to make the differences in the average practice times appear smaller. For example, we can change the range of the Y-axis from 0-15 to 8-14, since all the data points fall within this range. This would compress the data vertically and make the differences in the average practice times appear smaller.

Use a line graph instead of a bar graph to better show the trend of the data over time. This would allow us to see any patterns or trends in the average practice times over the course of the year.

Add a trend line or moving average to the graph to show the overall trend in the data and smooth out any fluctuations. This would further emphasize the consistency in the piano player's practice habits.

By making these adjustments, the graph would show that the piano player is consistently practicing for around 10-11 hours per week throughout the year, with some slight variations. This would convey the message that the piano player is dedicated and consistent in their practice habits.

Answer:

To find the inverse of the function p(x) = 4x - 8, we need to switch the x and y variables and solve for y.

Step 1: Replace p(x) with y.

y = 4x - 8

Step 2: Switch x and y variables.

x = 4y - 8

Step 3: Solve for y.

Add 8 to both sides:

x + 8 = 4y

Divide both sides by 4:

y = (x + 8)/4

Therefore, the inverse of the function p(x) = 4x - 8 is q(x) = (x + 8)/4.

Answer: To graph the linear equation x - y = 1, we can find its intercepts by setting one of the variables to zero and solving for the other.

Step-by-step explanation:

Setting x = 0, we get:

0 - y = 1

Solving for y, we get:

y = -1

So the y-intercept is (0, -1).

Setting y = 0, we get:

x - 0 = 1

Solving for x, we get:

x = 1

So the x-intercept is (1, 0).

Now we can plot the intercepts on a coordinate plane and draw a straight line passing through them:

In mathematics and statistics, the mean is a measure of central tendency of a set of numerical data. It is also known as the arithmetic mean or average, and is calculated by summing up all the values in the dataset and then dividing by the number of values. The mean provides a useful summary of the data as it gives an idea of the typical or average value in the dataset. It is commonly used in various fields, including finance, science, and social sciences, to analyze and interpret data. However, the mean can be sensitive to extreme values or outliers in the dataset, so it is important to consider other measures of central tendency, such as the median and mode, in addition to the mean.

Here,

We can approach this problem using the central limit theorem, which states that the distribution of sample means will be approximately normal, with a mean equal to the population mean and a standard deviation equal to the population standard deviation divided by the square root of the sample size.

Let's first calculate the standard error of the mean:

standard error of the mean = standard deviation / sqrt(sample size)

= 74 / √(39)

≈ 11.83

Next, we need to find the z-score corresponding to a sample mean within 14 pounds of the population mean:

z = (sample mean - population mean) / standard error of the mean

= (418 - 14 - 418) / 11.83

= -1.19

Using a standard normal distribution table or calculator, we can find that the probability of a z-score less than -1.19 is about 0.1171. Since we're interested in the probability that the sample mean is within 14 pounds of the population mean, we can multiply this probability by 2 to account for the area under the curve in both tails:

P(sample mean within 14 pounds of population mean) ≈ 2 * 0.1171 ≈ 0.2342

The types of functions are as follows:

1) Quadratic function

2) None of the above

3) Exponential function.

What is a function?

A relation between a set of inputs and a set of allowable outputs is called a function. It has the property that every input is associated with exactly one output. A function from one set X to another allocates precisely one element of the other set Y to each element of X. Both the set X and the set Y are referred to as the function's domain and codomain, respectively. The basic conception of functions was the relationship between fluctuating quantities and other variables.

The ways to determine the different functions are  as follows:

a) If for a constant change in x-values, the y-values also change constantly, the function is linear.

b) If as the x values change constantly, the y- values also change, but the difference in differences of y-values remains constant, then the function is quadratic.

c) If the ratio between two consecutive y- values is the same, when x-values change constantly, then the function is exponential.

Let us look into each function.

1) x-values are increasing constantly by one.

The difference in y-values are:

13-7 = 6

21-13 = 8

31-21 = 10

43-31 = 12

Now the difference of difference in y-values.

8-6 = 2

10-8 = 2

12-10 = 2

This is constant. So the function is a quadratic function.

2) The difference in y-values are:

-6+21 = 15

-21+30 = 9

-33+30=  -3

-30 + 33 = 3

This function can be categorised as none of the above.

3) The ratio of the consecutive y-values are:

-12/-3 = 4

-48/-12 = 4

-192/-48 = 4

-768/-192 = 4

Since the ratio is constant, the function is an exponential function.
