The solution that gives the maximum profit for the linear optimization question is presented as follows;

A maximum profit of $840 can be earned by investing;

$3,000 in stock A

$6,000 in stock B

$7,000 in stock C

Linear programming is a optimization technique that helps in determining the maximizing or minimizing parameters of linear functions.

The parameters in the question, obtained from a similar question obtained online includes;

The amount available to be invested = $16,000

The expected returns for stock A = 4%

The expected return for stock B = 5%

Expected returns for stock C = 6%

Amount to be invested in each stock ≥ $1,000

Amount to be invested in stock C ≤ $7,000

Amount invested in C ≤ 4 × Amount invested in stock A

Amount invested in stock B ≤ 2 × Amount invested in stock A

Let x represent the amount invested in stock A, let y represent the amount invested in stock B therefore;

The amount invested in stock C = 16,000 - x - y

16,000 - x - y ≥ 1000...(1)

16,000 - x - y ≤ 7000...(2)

16,000 - x - y ≤ 4·x...(3)

Therefore, we get;

- y ≥ 1000 - 16,000 = -15000 + x

-y ≥ -15000 + x

16,000 - x - y ≤ 7000

16,000 - x - y ≤ 4·x

-y ≤ 4·x + x = 5·x - 16,000

-y ≤ 5·x - 16,000  

The vertices of the feasible regions on the graph of the inequalities are;

(5,000, 10,000), (3,000, 6,000), (8,000, 1,000), and (14,000, 1,000)

The profit function is;

Profit = 0.04·x + 0.05·y + 0.06·(16000 - x - y)

Plugging in the value of the vertices of the feasible region in the profit function, we get;

Point (5,000, 10,000)

Profit = 0.04 × 5000 + 0.05 × 10000 + 0.06 × (16000 - 5000 - 10000) = 760

Point (3,000, 6,000)

Profit = 0.04 × 3000 + 0.05 × 6000 + 0.06 × (16000 - 3000 - 6000) = 840

Point (8,000, 1,000)

Profit = 0.04 × 8000 + 0.05 × 1000 + 0.06 × (16000 - 8000 - 1000) = 790

(14,000, 1,000)

Profit = 0.04 × 14000 + 0.05 × 1000 + 0.06 × (16000 - 14000 - 1000) = 670

Therefore, the maximum profit of $840 is earned by investing $3,000 in stock A and $6,000 in stock B which indicates that the investment in stock C is $16,000 - $3,000 - $6,000 = $7,000

Answer: A) No values of k are the expressions 12d + 8 and 4(3d + 5) - 8 equivalent.

They are the same if one amount or value has the same value as another.

We need to set the formulae 12d + 8 and 4(3d + 5) - 8 equal to one another and solve for k to get the values of k for which they are equivalent:

12d + 8 = 4(3d + 5) - 8

When we simplify this equation, we obtain:

12d + 8 = 12d + 12

When we take away 12d from both sides, we obtain:

8 = 12

There are no variables of k for which the expressions are similar because this equation is false for all values of d.

Since f(f1(y)) = y and f1(f(x)) = x, we can conclude that f1 is the correct inverse function for f.

Function can be defined in which it relates an input to output.

Given function ,

The function f(x) = x³ +9 is one-to-one.

To find the inverse function f1, we need to switch the roles of x and y in the equation for f(x). So, we have:

y = x³ + 9

Next, we need to solve for x in terms of y:

x³ + 9 = y

x³ = y - 9

x = (y - 9[tex])^{(1/3)}[/tex]

So, the inverse function is:

f1(y) = (y - 9[tex])^{(1/3)}[/tex]

To verify that f1 is the correct inverse function, we need to show that f(f1(y)) = y and f1(f(x)) = x:

f(f1(y)) = f((y - 9[tex])^{(1/3)}[/tex] = (y - 9[tex])^{(1/3)}^3[/tex] + 9 = y - 9 + 9 = y

And:

f1(f(x)) = f1(x³ + 9) = (x³ + 9 - 9[tex])^{(1/3)}[/tex] = [tex]\mathrm{ x^3^{(1/3)}}[/tex] = x

Therefore, Since f(f1(y)) = y and f1(f(x)) = x, we can conclude that f1 is the correct inverse function for f.

Answer:

Based on the information given, it seems like Messi and Ronaldo were asked to shoot the ball at two targets, target 1 and target 2, and the points they earned would be based on which target they hit.

In Test 1, Messi's first shot followed the equation 3(3x-4) = 24. To determine which target he hit, we need to solve for x. Using algebra, we can simplify the equation to 9x - 12 = 8, and then add 12 to both sides to get 9x = 20. Dividing both sides by 9, we find x = 2.2. Since x represents the number of points earned, this means Messi earned 2.2 points with this shot.

For Messi's second shot, the equation is 6.8 (2.3x + 5.7) = 132.6. To solve for x, we can start by dividing both sides by 6.8 to get 2.3x + 5.7 = 19.5. Subtracting 5.7 from both sides, we find 2.3x = 13.8. Dividing both sides by 2.3, we find x = 6.

In Test 2, Ronaldo's first shot followed the equation (6y-18) = 12. To solve for y, we can add 18 to both sides to get 6y = 30, and then divide both sides by 6 to get y = 5. This means Ronaldo earned 5 points with this shot.

For Ronaldo's second shot, the equation is 8.2 (-5) = -16.4. To solve for y, we need to determine the value of x. Since the equation is just a constant times a negative number, we can simplify it to 8.2 * -5 = -41. This means Ronaldo earned -41 points with this shot.

It's important to note that negative points are not possible in this scenario, as the targets only have positive point values.

a) The second stop is the third floor:

The first stop is the first floor, so the probability of going up from the first floor is 3/4.

The next stop is the third floor, so the probability of going up from the second floor (which is the first floor in this scenario) to the third floor is 3/4.

The probability of both events happening is the product of the individual probabilities: (3/4) * (3/4) = 9/16.

b) The third stop is the fourth floor:

The first stop is the first floor, so the probability of going up from the first floor is 3/4.

The next stop is the third floor, so the probability of going up from the first floor to the third floor is 3/4.

The next stop is the fourth floor, so the probability of going down from the third floor to the fourth floor is 1/4.

The probability of all three events happening is the product of the individual probabilities: (3/4) * (3/4) * (1/4) = 3/16.

c) The fourth stop is the first floor:

The first stop is the first floor, so the probability of going up from the first floor is 3/4.

The next stop is the third floor, so the probability of going up from the first floor to the third floor is 3/4.

The next stop is the fourth floor, so the probability of going down from the third floor to the fourth floor is 1/4.

The next stop is the first floor, so the probability of going down from the fourth floor to the first floor is 3/4.

The probability of all four events happening is the product of the individual probabilities: (3/4) * (3/4) * (1/4) * (3/4) = 9/64.

What is functions ?

In mathematics, a function is a relation between a set of inputs (called the domain) and a set of possible outputs (called the codomain or range) with the property that each input is related to exactly one output. Functions can be represented in many ways, including algebraic expressions, graphs, tables, or verbal descriptions.

Functions are widely used in various fields of mathematics, science, and engineering to model and analyse real-world phenomena, and to make predictions or decisions based on data.

There are 4 elements in the domain and an empty set in the codomain.

Using two-line notation, the functions are:

There is only one possible image for each element in the domain, which means that there is only one function.

Since there is only one function, it is both surjective and injective. Therefore, there is only one bijective function.

Answer:

Rafael and Lucy's credit for retirement plan contributions is $570.

Step-by-step explanation:

The Saver's Credit is a tax credit for low and moderate-income taxpayers who make contributions to a retirement plan. The credit is worth between 10% and 50% of the taxpayer's contributions, up to a maximum credit of $1,000 ($2,000 for married taxpayers filing jointly).

To determine the credit amount, we need to calculate the taxpayers' adjusted gross income (AGI) and their credit rate.

For the tax year in question, the AGI is $40,500 and the contribution limit is $2,850 per person. The total contribution amount is $2,850 x 2 = $5,700.

The credit rate is determined by the taxpayer's AGI and filing status, as follows:

For AGI up to $19,750 for married taxpayers filing jointly, the credit rate is 50%.

For AGI between $19,750 and $32,000 for married taxpayers filing jointly, the credit rate is 20%.

For AGI between $32,000 and $40,000 for married taxpayers filing jointly, the credit rate is 10%.

For AGI above $40,000 for married taxpayers filing jointly, the credit is not available.

Since the taxpayers' AGI is $40,500, the credit rate is 10%. The credit amount is calculated as follows:

Credit amount = Credit rate x Contribution amount

Credit amount = 10% x $5,700 = $570

So, Rafael and Lucy's credit for retirement plan contributions is $570.
