The given statement is FALSE. The determinant of the sum of two matrices does not equal the sum of the determinants of the matrices.

In fact, the determinant of the sum of two matrices is generally not even equal to the sum of the determinants of the matrices.
This property does not hold true for determinants. In general, the determinant of the sum of two matrices A and B

Answer:

Step-by-step explanation:

Answer:

The answer is x = \(\frac{-5}{3}\).

Step-by-step explanation:

First, we expand the brackets. Therefore:

\(2x+6 = -4x+(-4)\)

\(2x+6 = -4x -4\)

Then, we separate the like terms:

\(2x+4x = -4-6\)

Then we add the like terms up and solve for x:

\(6x = -10\)

Therefore:

\(x = \frac{-10}{6}\)

which, simplified, is:

\(x = \frac{-5}{3}\).

a. Switching from a production plan of 8,000 units to a plan of 10,000 units would result in an absorption costing operating income of $fill in the blank 2.

b. The difference in variable costing operating income between the two production plans can be calculated based on the change in the number of units produced.

a. To determine the absorption costing operating income, we need to consider both the fixed and variable costs. In absorption costing, fixed costs are allocated to each unit produced, while variable costs are directly attributed to the units. Given that the fixed costs are $40,000 and the variable cost per unit is $80, we can calculate the absorption costing operating income for each production plan

For the initial plan of 8,000 units:

Total fixed costs = $40,000

Total variable costs = 8,000 units * $80 per unit = $640,000

Total costs = Total fixed costs + Total variable costs = $40,000 + $640,000 = $680,000

For the revised plan of 10,000 units:

Total fixed costs remain the same at $40,000

Total variable costs = 10,000 units * $80 per unit = $800,000

Total costs = Total fixed costs + Total variable costs = $40,000 + $800,000 = $840,000

Absorption costing operating income = Sales - Total cost

b. Variable costing operating income differs between the two production plans as it only considers the variable costs directly associated with the units produced. In variable costing, fixed costs are treated as period costs and are not allocated to the units.

For the initial plan of 8,000 units:

Total variable costs = 8,000 units * $80 per unit = $640,000

For the revised plan of 10,000 units:

Total variable costs = 10,000 units * $80 per unit = $800,000

The difference in variable costing operating income between the two plans would be $800,000 - $640,000 = $160,000.

Given the functions f(x) and g(x), to determine the solutions of the equations f(x) = 0 and g(x) = 0, we need to find the values of x that make the functions equal to zero.

For f(x) = 0, we have f(x) = x^2 - 3x - 4 = 0. Using the quadratic formula, we get x = (-b ± sqrt(b^2 - 4ac)) / 2a, where a = 1, b = -3, and c = -4. Plugging in the values, we get x = -1 or x = 4 as the solutions to the equation f(x) = 0.

For g(x) = 0, we have g(x) = sqrt(x) - 2. To solve for x, we need to isolate the variable on one side of the equation. We have sqrt(x) - 2 = 0, which means sqrt(x) = 2. Squaring both sides, we get x = 4 as the solution to the equation g(x) = 0.

Therefore, the solutions to the equation f(x) = 0 are -1 and 4, while the solution to the equation g(x) = 0 is 4. These solutions are all real numbers, specifically rational numbers.

a) Cost of debt, I = 4.25%(annual)

b) After tax cost of debt = 3.315%

c) After tax cost of debt of 3.135% is more relevant.

Given:

FV = 100

Semiannual bond issued 3 years ago

Maturity = 27

Price, PV = 104

coupon rate = 4.5%

Tax rate = 22%

a) Semiannual bond issued 3 years ago

Maturity, n = 27 years × 2 = 54

Coupon C = 4.5%/2×100 = 2.25

Now,

Pretax cost of debt,

Cost of debt, I = [C+(FV-PV)/n] / (FV+PV)/2

= [2.25 +(100 - 104)/54] / [ 100+1040/2

= 2.12%

= 2.12×2

Cost of debt, I = 4.25%(annual)

b) After tax cost of debt = cost of debt × (1-T)

= 4.25% × (1-22%)

After tax cost of debt = 3.315%

c) After tax cost of debt is more relevant.

Hence we get the required answer.

The right answer is: E, according to the Central Limit Theorem for proportionality. The statistic is inaccurate.

In probability theory, the central limit theorem establishes that, in many situations, when independent random variables are summed up, their properly normalized sum tends toward a normal distribution even if the original variables themselves are not normally distributed.

The Central Limit Theorem establishes that for a proportion p in a sample of size n:

The expected value is μ=р

Answer: just graph it on the y-axis

Step-by-step explanation:

The Euler equation represents the relationship between current-period consumption and future-period consumption in the optimum. It is derived from intertemporal optimization in economics.

In the context of consumption, the Euler equation can be expressed as:

u'(Ct) = β * u'(Ct+1)

where:

- u'(Ct) represents the marginal utility of consumption in the current period,

- Ct represents current-period consumption,

- β is the discount factor representing the individual's time preference,

- u'(Ct+1) represents the marginal utility of consumption in the future period.

This equation states that the marginal utility of consumption in the current period is equal to the discounted marginal utility of consumption in the future period. It implies that individuals make consumption decisions by considering the trade-off between present and future utility.

Note: The Euler equation assumes a constant discount factor and a utility function that is differentiable and strictly concave.

The maximum volume of the box in terms of the height h is (30 - h/2)^2 x h, and the height that allows us to have the maximum volume is 40 inches

To answer your question, let's first understand that the volume of a box is given by the formula V = L x W x H, where L is the length, W is the width and H is the height. Since we are assuming the height is fixed, we can rewrite this formula as V = L x W x h.

Now, we know that the length plus width plus height of the box cannot exceed 60 inches. Therefore, we have the equation L + W + h = 60, which we can solve for L or W in terms of h. Let's solve for L: L = 60 - W - h.

Substituting this value of L into the formula for volume, we get V = (60 - W - h) x W x h. We can simplify this equation by expanding the brackets and collecting like terms to get V = -W^2h + 60Wh - h^2.

To find the maximum volume, we need to find the value of W that maximizes this equation. We can do this by differentiating the equation with respect to W and setting the derivative equal to zero. After some calculations, we get W = 30 - h/2.

Substituting this value of W back into the equation for volume, we get V = (30 - h/2)^2 x h. To find the height that gives us the maximum volume, we can differentiate this equation with respect to h and set the derivative equal to zero. After some calculations, we get h = 40 inches.

Therefore, the maximum volume of the box in terms of the height h is (30 - h/2)^2 x h, and the height that allows us to have the maximum volume is 40 inches.
