Yes, the graphs of a power function and its inverse are symmetric about the line y=x.

What is an inverse function?

A function that "undoes" another function is called an inverse. In other words, if f(x) yields y, then y entered into the inverse of f yields the output x. An invertible function is one that has an inverse, and the inverse is represented by the symbol f⁻¹.

What is a power function?

Any function where y = xⁿ, where n is any real constant integer, is referred to be a power function. In reality, many of our parent functions, including linear and quadratic functions, are power functions.

Here,

The graphs of self-inverse functions are symmetrical about the line y=x. The domain of a one-to-one function f is the same as the range of its inverse f⁻¹ and the range of f is the same as the domain of f⁻¹.

Hence, the graphs of a power function and its inverse are symmetric about the line y=x.

Sorry if this isnt enough, but i am sure.

Answer:

D.  11 < x < 19.

Step-by-step explanation:

The third side x is between 11 and 19 cm.

Consider sides AB (length 4) and BC (length 15) of the triangle.

Consider the angle between AB and BC is slightly less than 180 degrees.  To get from point A to point C, we have to travel almost the entire length of A to C, which is from A to B and then B to C, so a bit less than 19 cm.

Consider the angle between AB and BC is slightly more than 0 degrees.  To get from point A to point C, we subtract the length of AB (because we're already further along BC), so 15 - 4, a bit greater than 11.

The solution of the linear equation in one variable 4y - 6 = 2y + 8 is at y = 7.

According to the given question.

We have a linear equation in one variable.

4y - 6 = 2y + 8

As we know that, the linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.

Thereofre, the solution of the linear equation in one variable 4y - 6 = 2y + 8 is given by

4y - 6 = 2y + 8

⇒ 4y - 2y - 6 = 8     ( subtracting 2y from both the sides)

⇒ 2y -6 -8 = 0           (subtracting 8 from both the sides)

⇒ 2y - 14 = 0

⇒ 2y = 14

⇒ y = 14/2

⇒ y = 7

Hence, the solution of the linear equation in one variable 4y - 6 = 2y + 8 is at y = 7.

Explanation:

Given;

Long distance calls cost 18 cents a minute = $0.18 per minute

Initial credit = $15

Final credit after call = $8.16

The amount of credit C used to make the long distance call is;

C= initial - final credit

C = $15 - $8.16

C = $6.84

Then the number of minutes N used can be calculated by;

R = rate = $0.18 per minute

substituting we have;

Threrefore, her last call was 38 minutes

We know how many pounds are needed to cover 5000 ft^2, and we need to find how many are needed to cover 27000ft^2. To find this value, divide 27000 by 5000 and multiply the result by the weight.

27000/5000 x 18.75
5.4 x 18.75
101.25

So, we need 101 1/4 pounds of fertilizer. How many bags is that?

101.25/18.75

We'll say that since the 0.4 of a bag will still need to be used, that you need 6 bags to cover 27000ft^2.

Main Answer:The approximate probability is 0.033

Supporting Question and Answer:

How do we calculate the expected average and standard deviation for a sample?

To calculate the expected average and standard deviation for a sample, we need to consider the characteristics of the population and the sample size.

Body of the Solution:

a) To find the expected average amount of the waiter's tips, we can use the fact that the mean of the sample means is equal to the population mean. Since the mean of the tips is given as 7 dollars, the expected average amount of his tips is also 7 dollars.

b) The standard deviation for the average amount of the waiter's tips, also known as the standard error of the mean, can be calculated using the formula:

Standard deviation of the sample means

= (Standard deviation of the population) / sqrt(sample size)

In this case, the standard deviation of the population is given as 2 dollars, and the sample size is 30. Plugging these values into the formula, we have:

Standard deviation of the sample means = 2 / sqrt(30) ≈ 0.365

Therefore, the standard deviation for the average amount of the waiter's tips is approximately 0.365 dollars.

c) To find the approximate probability that the average amount of the waiter's tips is less than 6 dollars, we can use the Central Limit Theorem, which states that for a large sample size, the distribution of sample means will be approximately normal regardless of the shape of the population distribution.

Since the sample size is 30, which is considered relatively large, we can approximate the distribution of the sample means to be normal.

To calculate the probability, we need to standardize the value 6 using the formula:

Z = (X - μ) / (σ / sqrt(n))

where X is the value we want to standardize, μ is the population mean, σ is the population standard deviation, and n is the sample size.

Plugging in the values, we have:

Z = (6 - 7) / (2 / sqrt(30)) ≈ -1825

Using a standard normal distribution table or a calculator, we can find the probability associated with this z-score. The approximate probability that the average amount of the waiter's tips is less than 6 dollars is approximately 0.033.

Final Answer:Therefore, the approximate probability is 0.033, accurate to three decimal places.

An area of mathematics that studies how competing parties interact is known as "game theory."

Game theory analyzes strategic decision-making in situations where multiple participants, known as players, make choices that affect each other's outcomes. It examines the interactions, strategies, and outcomes of these competitive or cooperative situations.

Game theory provides mathematical models and frameworks to analyze various scenarios, such as conflicts, negotiations, auctions, voting systems, and economic markets. It studies the behavior of rational players, their objectives, and the choices they make to maximize their own outcomes, considering the actions and reactions of other players.

The field of game theory explores concepts such as strategies, payoffs, Nash equilibrium, dominant strategies, and cooperative or non-cooperative games. It aims to predict and understand the behavior and outcomes of competitive situations and provides insights into decision-making, resource allocation, and the dynamics of interactions between individuals, organizations, or even nations.

Overall, game theory serves as a valuable tool in various disciplines, including economics, political science, psychology, and computer science, to analyze and model situations where competing parties interact.

Except for the apparently added value of 3 with every term, the terms have a common ratio of 5. After subtracting 3, the first term (for x=0) has a value of 20. This is the multiplier.

The exponential function is ...

  f(x) = 20(5^x) +3

Additional comment

We see numerous questions on Brainly where the exponent (or denominator) of a number appears to be an appended digit. The "3" at the end of each of the numbers here suggests it might not actually be the least significant digit of the number, but might represent something else.

If the sequence of f(x) values is supposed to be 2/3, 10/3, 50/3, ..., then the exponential function will be ...

  f(x) = 2/3(5^x)

This makes more sense in terms of the kinds of exponential functions we usually see in algebra problems. However, there is nothing in this problem statement to support that interpretation.

a. The addition to retained earnings is $370,120,000.

b. The dividend yield was 69.52%.

a. The amount paid out as dividends can be calculated as:

Dividends = Earnings x Dividend payout ratio

Dividends = $487,000,000 x 0.24

Dividends = $116,880,000

Therefore, the addition to retained earnings would be:

Addition to retained earnings = Earnings - Dividends

Addition to retained earnings = $487,000,000 - $116,880,000

Addition to retained earnings = $370,120,000

b. Dividends per share can be calculated by dividing the total dividends paid by the number of outstanding shares:

Dividends per share = Dividends / Number of shares

Dividends per share = $116,880,000 / 100,000,000

Dividends per share = $1.1688 per share

The dividend yield can then be calculated as:

Dividend yield = Dividends per share / Stock price x 100%

Dividend yield = $1.1688 / $168 x 100%

Dividend yield = 0.6952 x 100%

The quantity of trays that were in each of the cartons the manager unloaded was 12 trays.

To determine the quantity of trays in each carton, we need to analyze the given information step by step:

From these points, we can deduce the following:

Now, let's solve for the number of trays in each carton.

Let's assume that the number of trays in each carton is "x."

We know that 24 trays were taken initially, and each serving line ended up with 12 trays. So, we can set up the equation:

24 + 12 + 12 + 12 = 4x

48 = 4x

Dividing both sides of the equation by 4:

12 = x

The cost of cleaning each shirt is 3 dollars.

A linear equation is an algebraic equation of degree one. In general, the variable or the variables(in the case of a linear equation in two variables) the variables are x and y.

Assuming the cost of cleaning 1 shirt is x and the cost of cleaning 1 pant is y.

The first customer paid $30.00 for 5 shirt cleanings and 3 pants cleaning.

∴ 5x + 3y = 30...(i)

The second customer paid $29.00 for 3 shirt cleanings and 4 pants cleaning.

∴ 3x + 4y = 29...(ii)

Now to cancel out 'x' in both equations we multiply eqn(i) by 3 and eqn(ii) by 5.

So, 15x + 9y = 90...(iii) and 15x + 20y = 145...(iv)

Now subtracting (iii) from (iv) we get 11y = 55 ⇒ y = 5 and substituting the value of y in eqn(iv) we get x = 3.
