Farmer Ed has 3,000 meters of fencing and wants to enclose a rectangular plot that borders on a river.The largest area that can be enclosed is 750,000 square meters.

To get the largest area that can be enclosed, we have to find the dimensions of the rectangular plot. Let's assume that the width of the rectangle is x meters.The length of the rectangle can be found by subtracting the width from the total length of fencing available:L = 3000 - x. The area of the rectangle can be found by multiplying the length and width:Area = L × W = (3000 - x) × x = 3000x - x²To find the maximum value of the area, we can differentiate the area equation with respect to x and set it equal to zero.

Then we can solve for x: dA/dx = 3000 - 2x = 0x = 1500. This means that the width of the rectangle is 1500 meters and the length is 3000 - 1500 = 1500 meters.The area of the rectangle is therefore: Area = L × W = (3000 - 1500) × 1500 = 750,000 square meters. So the largest area that can be enclosed is 750,000 square meters.

To find three positive numbers whose sum is 12 and the sum of their squares is as small as possible, the three numbers would be 2, 4, and 6.

Let's assume the three positive numbers are x, y, and z. We want to minimize the sum of their squares, which can be represented as x^2 + y^2 + z^2. Given that the sum of the three numbers is 12, we have the equation x + y + z = 12.

To minimize the sum of squares, we can use the principle of minimizing the sum of squares of two numbers when their sum is fixed. According to this principle, the sum of squares is minimized when the two numbers are closest to each other.

Considering the sum of 12, the two numbers closest to each other would be 4 and 4, which gives a sum of squares of 4^2 + 4^2 = 32.

However, we need to find three numbers, not just two. To include the third number, we can set it to 12 - 4 - 4 = 4, so that the sum of the three numbers remains 12.

The three positive numbers, in this case, would be 2, 4, and 6, with a sum of squares equal to 2^2 + 4^2 + 6^2 = 56.

Therefore, the three positive numbers that satisfy the given conditions and minimize the sum of their squares are 2, 4, and 6.

Answer:

The slope is 5/3

Step-by-step explanation:

5x - 3y = 4

Solve for y

Subtract 5x from each side

5x-5x - 3y =-5x+ 4

-3y = -5x+4

Divide each side by -3

-3y/-3 = -5x/-3 +4/-3

y = 5/3x -4/3

This is in the form

y =mx+b

The slope is m and the y intercept is b

The slope is 5/3

The  solution of the given system of equations is (8, -1). of the given system of equations is (8, -1).

One method to solve the given system of equations is substitution:

- Solve one of the equations for one of the variables (e.g., x = 9 + y from the second equation).

- Substitute the expression for the variable into the other equation.

- Solve the resulting equation for the remaining variable.

- Substitute the value for the remaining variable back into one of the original equations to find the value of the other variable

Using this method with the given equations

- x - y = 9 -> x = 9 + y

- 3x + 2y = 22 -> 3(9 + y) + 2y = 22

- Simplifying and solving for y: 27 + 5y = 22 -> 5y = -5 -> y = -1

- Substituting y = -1 into x = 9 + y: x = 8

To check this solution, we can substitute these values back into both original equations and confirm that they are true statements.

The dividend in 2018 was $2.95, and it is expected to grow at a rate of 7.4% for the next five years and 2.6% thereafter. With an equity cost of capital of 8.6%, the value per share at the end of 2018 can be calculated.

To calculate the value per share at the end of 2018, we need to discount the expected future dividends using the dividend-discount model. The model assumes that the value of a stock is equal to the present value of all its expected future dividends.

First, we need to calculate the dividends for each year from 2019 to 2023. We start with the dividend in 2018, which was $2.95. We then increase it by 7.4% each year for the next five years:

Dividend in 2019 = $2.95 * (1 + 7.4%) = $3.17

Dividend in 2020 = $3.17 * (1 + 7.4%) = $3.40

Dividend in 2021 = $3.40 * (1 + 7.4%) = $3.65

Dividend in 2022 = $3.65 * (1 + 7.4%) = $3.92

Dividend in 2023 = $3.92 * (1 + 7.4%) = $4.22

After 2023, the dividend is expected to grow at a rate of 2.6% per year. To find the value per share at the end of 2018, we discount the future dividends to their present value using the equity cost of capital of 8.6%.

The present value of the dividends can be calculated as follows:

PV = (D1 / (1 + r)) + (D2 / (1 + r)^2) + ... + (Dn / (1 + r)^n)

where PV is the present value, D1 to Dn are the dividends for each year, r is the equity cost of capital, and n is the number of years.

In this case, n = 5 because we are discounting the dividends for the next five years. Let's calculate the present value:

PV = ($3.17 / (1 + 8.6%)) + ($3.40 / (1 + 8.6%)^2) + ($3.65 / (1 + 8.6%)^3) + ($3.92 / (1 + 8.6%)^4) + ($4.22 / (1 + 8.6%)^5)

PV = $3.17 / 1.086 + $3.40 / 1.086^2 + $3.65 / 1.086^3 + $3.92 / 1.086^4 + $4.22 / 1.086^5

PV ≈ $2.91 + $3.07 + $3.24 + $3.41 + $3.59

PV ≈ $16.22

Therefore, the estimated value per share of Procter and Gamble at the end of 2018 using the dividend-discount model is approximately $16.22.

We can solve the Inequalities by Isolating the variables that are present in the given Inequality.

In mathematics, an inequality is a connection between two values or mathematical equations that results in an unequal comparison.

The signs that we use in Inequalities are less than( < ), less than or equal to ( ≤ ), greater than ( > ), greater than or equal to ( ≥ ), and not equal to (≠) sign.

Lets us consider we have inequality 3x + 2 + x ≥ 10

We can solve the above inequality as given below

Here we will solve the inequality by Isolating the variable  

Step - 1

Add x term and constant terms

=> 4x + 2 ≥ 10   [ here 3x + x = 4x ]

Step - 2  

Bring out x terms at one side, and constant terms at another side by doing required operations like adding

=> 4x + 2 ≥ 10    [ here we will subtract 2 from both sides ]

=> 4x + 2 - 2  ≥ 10 - 2

=> 4x  ≥ 8  

Step - 3

Now isolate the variable to get the solution

=>  4x/4  ≥ 8/4         [ here divided by 4 ]

=> x  ≥ 2  

Therefore, the required solution is x ≥ 2    

Therefore,

Based on the information, dn is a common divisor of an and bn, and it is also the greatest common divisor.

Since k is a divisor of an, we have an = kp for some natural number p.

Similarly, bn = kq for some natural number q.

Substituting these values into the equations for an and bn:

an = (dr)n = dnr

bn = (ds)n = dns

Since k is a common divisor of an and bn, we have:

dnr = kp ... (1)

dns = kq ... (2)

Now, let's consider equation (1). Since d divides k, we can write k = dl for some natural number l.

Substituting this into equation (1):

dnr = dlp

nr = lp

Since n and r are natural numbers, lp is also a natural number. Therefore, n divides lp.

Similarly, equation (2) gives us:

dns = dls

ns = ls

Again, since n and s are natural numbers, ls is also a natural number. Therefore, n divides ls.

In conclusion, we have shown that dn is a common divisor of an and bn, and it is also the greatest common divisor. Thus, we have proven that gcd(an, bn) = dn for every natural number n, given gcd(a, b) = d.

The sampling distribution of the sample mean for samples of size 16, then, is 3.2 pets, which is the same as the mean number of pets owned by the population of students at the high school.

The mean number of pets owned by the population of students at a large high school is 3.2 pets per student with a standard deviation of 1.7 pets. To better understand this population, a random sample of 16 students will be taken and the mean number of pets for the sample will be calculated.

This will provide us with the mean of the sampling distribution of the sample mean for samples of size 16.

To calculate this, we will first calculate the standard error of the mean, which is the standard deviation of the sample mean. This is calculated by dividing the population standard deviation (1.7 pets) by the square root of the sample size (16), resulting in a standard error of the mean of 0.43.

This means that the standard deviation of the sample means is 0.43 pets.

Answer: There were 78 red apples at the party.

Step-by-step explanation:

This situation can be represented by the equation  

x + 3x + 2(3x) = 130    where x is the number of green apples, 3x is the number of  yellow apples and 2(3x) is the number  of red apples.

Now solve for x

x +3x +2(3x) =130

4x + 6x = 130

10x  = 130

x =  13  

Now we know that x is 13 so put it into the expression for red apples and solve for the actual number of red apples.

The probability that the chosen card is a diamond is 3/13. According to the definition of probability, which is "the degree to which something is probable; the likelihood of something happening or being the case," there is a 1/13 chance that none of the cards will be diamonds.

Probability is simply the likelihood that something will happen. The likelihood or likelihood of various outcomes can be discussed when we don't know how an event will turn out. The study of events that fit into a probability distribution is known as statistics. The full range of potential outcomes is known as the sample space, or individual space, of a random experiment. The likelihood of any event occurring ranges from 0 to 1. Probability is the study of random events in mathematics, and it can be classified into four main categories: axiomatic, classical, empirical, and subjective. You could say that probability is the likelihood that a particular event will occur because probability and possibility are synonyms.

Here,

a. Given that there are 13 diamond cards, the probability that all the cards are diamonds is 3/13.

b. the likelihood that none of the 52 cards, with 13 diamond cards, are diamonds.

unused card = 52-13 = 39 = 3/39

There is a 3/13 chance that the selected card will be a diamond. There is a 1/13 chance that no cards will be diamonds, according to the definition of probability, which is "the degree to which something is probable; the likelihood of something happening or being the case."
