Numbers: 6 and -2

Step-by-step explanation:

Equations

This question can be solved by inspection. It's just a matter of factoring 12 into two factors that sum 4. Both numbers must be of different signs and they are 6 and -2. Their sum is indeed 6-2=4 and their product is 6*(-2)=-12.

However, we'll solve it by the use of equations. Let's call x and y to the numbers. They must comply:

[tex]x+y=4\qquad\qquad [1][/tex]

[tex]x.y=-12\qquad\qquad [2][/tex]

Solving [1] for y:

[tex]y=4-x[/tex]

Substituting in [2]

[tex]x(4-x)=-12[/tex]

Operating:

[tex]4x-x^2=-12[/tex]

Rearranging:

[tex]x^2-4x-12=0[/tex]

Solving with the quadratic formula:

[tex]\displaystyle x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

With a=1, b=-4, c=-12:

[tex]\displaystyle x=\frac{-(-4)\pm \sqrt{(-4)^2-4(1)(-12)}}{2(1)}[/tex]

[tex]\displaystyle x=\frac{4\pm \sqrt{16+48}}{2}[/tex]

[tex]\displaystyle x=\frac{4\pm 8}{2}[/tex]

The solutions are:

[tex]\displaystyle x=\frac{4+ 8}{2}=6[/tex]

[tex]\displaystyle x=\frac{4- 8}{2}=-2[/tex]

This confirms the preliminary results.

Step-by-step explanation:

You want the sum of four 2-digit prime numbers that can be formed from the set of digits {1, 2, 3, 4, 5, 6, 7, 9} using each digit only once.

There are 18 primes in the range 13-97 that have unique digits. These can be paired by the digits they use:

  {23, 59} and {29, 53} . . . . number total = 82

  {41, 67} and {47, 61} . . . . . number total = 108

A set of 4 primes with unique digits can be formed by choosing one of the first two pairs together with one of the second two pairs. For example, one possible choice is ...

  {23, 59, 47, 61}

However you do this, the sum of the four primes will be ...

  82 +108 = 190

The optimal solution for the given linear programming problem using the graphical solution procedure is at (A, B) = (6, 2) with the objective function value of -4.

To find the optimal solution graphically, we plot the feasible region determined by the constraints. In this case, the feasible region is a polygon bounded by the lines 2A + 3B = 12, A + 4B ≤ 21, 2A + B ≥ 7, 3A + 1.5B ≤ 21, and -2A + 6B ≥ 0. We then evaluate the objective function -2A - B at the vertices of the feasible region to determine the optimal solution. The vertex that gives the minimum value of the objective function is the optimal solution. By calculating the objective function at each vertex, we find that the minimum value of -4 is obtained at (A, B) = (6, 2). This means that the optimal solution is to set A = 6 and B = 2, and the objective function value at this point is -4. For part (b), to determine the amount of slack or surplus for each constraint, we evaluate the constraints at the optimal solution (A, B) = (6, 2). For the constraint 1A + 4B ≤ 21, the left-hand side is 1(6) + 4(2) = 14, which indicates a slack of 7 (21 - 14). For the constraint 2A + 1B ≥ 7, the left-hand side is 2(6) + 1(2) = 14, which indicates a surplus of 7 (14 - 7). For the constraint 3A + 1.5B ≤ 21, the left-hand side is 3(6) + 1.5(2) = 20, which indicates a slack of 1 (21 - 20). Lastly, for the constraint -2A + 6B ≥ 0, the left-hand side is -2(6) + 6(2) = 4, which indicates a surplus of 4 (4 - 0). These slack and surplus values represent the amount by which the left-hand side of each constraint falls short or exceeds the right-hand side at the optimal solution. A positive slack indicates that the constraint is not fully utilized, while a positive surplus indicates that the constraint is exceeded.

We are given three conic sections: a parabola, a hyperbola, and a new conic section with its center at point K(1, -1) and passes through points L(0, 0) and M(-1, 1). We need to determine the correct letter(s) that represent these conic sections.

To identify the conic sections, let's analyze the given information. The center of the new conic section is at point K(1, -1), and it passes through points L(0, 0) and M(-1, 1).

Since a parabola is determined by its focus and directrix, and a hyperbola has two foci, it is unlikely that either of these conic sections can be uniquely determined based on the given information.

Therefore, without additional information about the nature of the conic sections (e.g., the eccentricity for hyperbola or the vertex and axis of symmetry for parabola), we cannot definitively determine the correct letter(s) to represent these conic sections. It is possible that the correct letter(s) could be CO, L, or none of them.

In conclusion, without further information, we cannot determine the exact conic sections represented by the given points.

The given conditions cannot form a triangle. The sum of the angles in a triangle must be 180 degrees. In this case, the sum of the angles is 100 degrees (50 + 50). Therefore, there is no possible value for angle h.

Here is the calculation:

Angle G + Angle H + Angle I = 180

50 + Angle H + Angle I = 180

Angle H + Angle I = 180 - 50

Angle H + Angle I = 130

Since the sum of angle h and angle i is 130 degrees, there is no possible value for angle h that will result in a triangle with a total angle measure of 180 degrees.

Interest-free or below-market interest loans are a taxable benefit, and their value must be included in the employee's gross income. For federal tax purposes, the rate charged on the loan should be equal to or greater than the Applicable Federal Rate (AFR) set by the IRS.

If the loan's interest rate is lower than the AFR, the difference between the AFR and the loan rate is considered a gift or taxable interest. If the borrower is an employee, the taxable interest is compensation and must be reported as such.

On September 1, 2021, Carol Mason received a $150,000 loan from her employer at a 1% interest rate. The relevant prescribed rate was 2 % in Q3 and 3% in Q4. We must calculate the benefit's value. There are two ways to calculate the value of a taxable benefit: the loan's interest-rate differential method and the loan's principal-amount method.Let's start with the interest-rate differential method.The difference between the interest rate on the loan and the prescribed rate on the day the loan was made, multiplied by the loan principal and divided by the number of days remaining in the year, is the amount of taxable interest using this method.

To begin, we must calculate the relevant prescribed rate for Carol's loan. It is 2% in Q3 (July 1, 2021, to September 30, 2021) and 3% in Q4 (October 1, 2021, to December 31, 2021). Since Carol received the loan on September 1, 2021, she would be liable for the 2% interest rate for the rest of Q3 and the 3% rate for the rest of the year (Q4).2% for 30 days in September and 3% for 91 days in Q4 are the equivalent annual rates.The interest rate differential can be calculated using the formula below:($150,000 × (3 percent – 1 percent) ÷ 365 × 122) + ($150,000 × 2 percent ÷ 365 × 243) = $1,017.81.Carol would need to report $1,017.81 as taxable interest on her 2021 tax return using the interest rate differential method.

The loan principal amount method is the second approach. The loan principal method assumes that the loan was provided on the first day of the year and repaid on the last day of the year using the prescribed rate interest.Carol's loan has a principal of $150,000. The interest on the loan at the prescribed rate for Q3 (2%) and Q4 (3%) can be calculated using this method. The total interest on the loan is the sum of the two interests.To determine the taxable interest using the principal amount method, multiply the average prescribed rate of 2.5% by the $150,000 loan principal, then divide by 12 months. Carol would need to report $3,750 as taxable interest on her 2021 tax return using the principal amount method.

The amount of benefit to be included in Carol’s tax return for 2021 is $1,017.81 if the interest rate differential method is used. If the principal amount method is used, the amount of benefit to be included in Carol’s tax return for 2021 is $3,750. Thus, the correct option among the given options is D) $250.

If you have access to a linear programming solver or software like Excel Solver or MATLAB's Optimization Toolbox, you can enter the dual problem and use the solver to obtain the optimal solution.

To solve the dual of the given problem using the dual simplex algorithm, we first need to rewrite the primal problem in standard form. The primal problem is as follows:

Maximize: z = 11x + x + 6w

Subject to:

6x + 15x - 3w ≥ 60

3x + 2x + w ≤ 21

2x + 3x - w = 34

x ≥ 0, y ≥ 0, w ≥ 0

The dual problem will have the following form:

Minimize: w = 60y + 21z + 34u

Subject to:

6y + 3u + 2v ≥ 11

15y + 2u + 3v + u + v ≥ 1

-3y + v = 6

y ≥ 0, u ≥ 0, v unrestricted

Now, we can apply the dual simplex algorithm to solve the dual problem. The steps involved in the dual simplex algorithm include:

Start with an initial feasible solution.

Check for optimality.

If not optimal, select a pivot column and pivot row.

Perform row operations to make the pivot element 1 and all other elements in the pivot column 0.

Repeat steps 2-4 until the optimal solution is reached.

The detailed calculations and iterations involved in the dual simplex algorithm can be quite lengthy and involve complex matrix operations. It would be best to use a specialized software or linear programming solver to perform these calculations accurately and efficiently.

Starstruck Inc. should report approximately $8,767 as the amount of interest expense on its income statement for the year ended December 31, 2021.

To calculate the amount of interest expense that Starstruck Inc. should report on its income statement for the year ended December 31, 2021, we need to determine the interest accrued for the 14-month period from November 1, 2020, to December 31, 2021.

The formula to calculate interest expense is:

Interest Expense = Principal * Interest Rate * Time

Principal = $300,000

Interest Rate = 8% per year

Since the note is an 8-month note, we need to calculate the interest for the 14-month period.

We can use the following formula to calculate the time in years:

Time = Number of days / Days in a year

Number of days from November 1, 2020 to December 31, 2021 = 426 days

Days in a year = 365 days

Time = 426 / 365

Now we can calculate the interest expense:

Interest Expense = $300,000 * 8% * (426 / 365)

Interest Expense ≈ $8,767.12
