Step-by-step explanation:

The both statements are proved that,

(a) If A be an n*n matrix and is singular matrix then adj A is also singular.

(b) If n ≥ 2, then |adj (A)| = |A|ⁿ⁻¹.

Given that the A is a matrix of order n*n.

(a) So, |adj (A)| = |A|ⁿ⁻¹

When A is a singular so, |A| = 0

So, |adj (A)| = |A|ⁿ⁻¹ = 0ⁿ⁻¹ = 0

Hence, adj(A) is also singular matrix.

(b) Now, we know that,

A*adj(A) = |A|*Iₙ, where Iₙ is the identity matrix of order n*n.

Now taking determinant of both sides we get,

|A*adj(A)| = ||A|*Iₙ|

|A|*|adj (A)| = |A|ⁿ*|Iₙ|, since A is a matrix of n*n

|A|*|adj (A)| = |A|ⁿ, since |Iₙ| = 1, identity matrix.

|adj (A)| = |A|ⁿ/|A|

|adj (A)| = |A|ⁿ⁻¹

Hence the second statement is also proved.

Slope formula

\(\frac{y2-y1}{x2-x1}\)

Plug in your numbers

\(\frac{4-1}{-8-(-2)}\)

(-8-(-2) would turn into -8+2 because they are both negative.

\(\frac{4-1}{-8+2} = \frac{3}{-6}\)

Simplify.

There are a couple ways we can get the equation of a line, depending on what we're given.

Most linear equations are organized in slope-intercept form:

\(y=mx+b\)

The slope of a line can be calculated algebraically when we know two points that fall on the line:

\(m=\dfrac{y_2-y_1}{x_2-x_1}\)

The y-intercept is the value of y when the line crosses the y-axis, or when x = 0. When given a graph, you can sometimes read the y-intercept directly from the graph.

For instance, if the line passes through the point (0,5), then the y-intercept is 5.

You can also find the y-intercept algebraically if you know the slope and one point that falls on the line. You plug in that point as (x,y) and isolate b.

For most cases, you can use the following method to find the equation of a line:

The weekly goal of 150 minutes of moderate exercise or 75 minutes of intense exercise has increased by 22.9 percent.

The intensity of exercises depends on mostly the amount of energy you have to spend. But the time spent also differs. Intense exercises are basically exercises that require you to expend more energy than how much you spend on normal exercise. Any exercise becomes intense when you spend 70 to 85 percent of your maximum heart rate working out. It is vigorous but you get the same amount of calories burned.

Moderate exercises are the normal ones. These require normal intake of heart rate and energy but take more time. The walk from your house to your college/school or the normal crunches and all you do are perfect examples of moderate exercises.

To find the interest of Chris Owens’ credit union loan of $3,290 at 10(1/3)% interest for 110 days, we use the simple interest formula as follows:

Simple Interest = (P × R × T)/100Where:P = Principal or amount borrowedR = Rate of interest per annumT = Time in years or fraction of a year110 days ÷ 360 days = 0.3056 (time as a fraction of a year)The rate of interest, 10(1/3)% is equal to 10 + (1/3) percent = 10.33% per annum in decimal form = 0.1033Substituting the values we have into the formula,Simple Interest = (P × R × T)/100= (3,290 × 0.1033 × 0.3056)/100= $100.68 (rounded to the nearest cent)

Therefore, the interest of Chris Owens’ credit union loan of $3,290 at 10(1/3)% interest for 110 days is $100.68.

A credit union loan is a type of personal loan that can be used for a variety of purposes. One of the most common reasons people take out credit union loans is to purchase big-ticket items like a new computer system. When you take out a loan, you must pay back the amount borrowed plus the interest charged by the lender. The interest rate is usually expressed as a percentage of the amount borrowed and is charged for a specific period of time known as the loan term. Simple interest is a method of calculating interest that is charged only on the principal amount borrowed.

It does not take into account the interest that has already been paid. Simple interest is calculated by multiplying the principal amount borrowed by the interest rate and the length of the loan term. The answer is more than 100 words.The interest of Chris Owens’ credit union loan of $3,290 at 10(1/3)% interest for 110 days is $100.68. Therefore, he would pay $3,290 + $100.68 = $3,390.68 in total to the credit union over the loan term. It is important to note that when rounding dollar amounts to the nearest cent, amounts that end in .50 or higher are rounded up to the next highest cent, while amounts that end in .49 or lower are rounded down to the next lowest cent. In this case, $100.6847 would be rounded up to $100.68. In conclusion, the interest charged on a loan can significantly increase the total amount that must be repaid, making it important for borrowers to understand how interest is calculated and the terms of their loan.

The value of the goods in the box is 4,500.50 lei.

The volume of an imaginary box made of 2,000 cubes with a side of 1 m would be:

Volume = (1 m * 1 m * 1 m) * 2,000 = 2,000 m^3

However, the statement claims that the imaginary box holds the same type of goods, worth 9001000 lei. This would mean that the value of the goods in the imaginary box is more than 200 times the value of the goods in the real box, which seems highly unlikely. Therefore, the statement is false.

The estimated revenue, in dollars, that the club will generate when the bags are priced at $13 each is 3) 1,040.

The revenue formula is the multiplication of the number of units sold and the price per unit.

To determine the total revenue, we must first ascertain the unit price and the quantity sold.

We know that market forces and the competitive environment determine the quantity sold or supplied.

The demand for tote bags at $11 = 100 units

Decrease in demand for every $1 price increase = 10 units

When the price is $13 each, the units to be sold = 80 (100 -10 x 2)

The total revenue at $13 each = $1,040 (80 x $13)

Total revenue at $12 each = $1,080 (90 x $12)

Total revenue at $11 each = $1,100 (100 x $11)

Thus, we can conclude that the club generates less revenue when it increases its price per tote bag from $11 to $13, justifying the interactions between supply, demand, and cost.

The new variance is 0.0625 / n

We can use the following formula to calculate the variance of a data set

variance = (sum of (x - mean)^2) / (number of data points)

where x is a data point and mean is the mean of the data set.

If the mean cost of a box of Cheerios Oat Crunch is $4.00 and the variance is 0.35, we can find the standard deviation as follows

standard deviation = square root of variance = sqrt(0.35) = 0.59

Now, if the price increases by 25 cents a box, the new mean cost will be

new mean = $4.00 + $0.25 = $4.25

To find the new variance, we need to calculate the sum of (x - mean)^2 for the new data set and divide by the number of data points. Let's assume we are still considering the same number of boxes.

sum of (x - mean)^2 = [(4.25 - 4)^2 × n] = 0.0625 × n

where n is the number of data points.

Therefore, the new variance can be calculated as

new variance = (sum of (x - mean)^2) / (number of data points) = 0.0625 / n

The statements 1 and 2 are false. When units manufactured are less than the number of units sold, the variable costing income from operations will be greater than the absorption costing income from operations.

The statement 1 is false. In absorption costing, both fixed and variable factory costs are included in the cost of goods sold.

This is because absorption costing assigns a portion of fixed factory costs to each unit of production, treating them as a product cost.

Variable factory costs, which vary with the level of production, are also included in the cost of goods sold. This method aims to allocate both fixed and variable costs to the units produced.

The statement 2 is also false. In variable costing, only variable factory costs are included in the cost of goods sold.

Fixed factory costs are treated as period costs and are not assigned to individual units of production.

Instead, they are expensed in the period incurred. This method provides a clearer picture of the cost behavior and allows for better analysis of the contribution margin.

When units manufactured are less than the number of units sold, the variable costing income from operations will be greater than the absorption costing income from operations.

This is because variable costing treats fixed factory costs as period costs and does not allocate them to the units produced.

As a result, the fixed costs incurred in the period are not absorbed into the cost of goods sold.

In contrast, absorption costing assigns a portion of fixed factory costs to each unit, so when fewer units are produced and sold, the fixed costs are spread over a smaller number of units, leading to higher per-unit costs and lower income from operations compared to variable costing.

Therefore, the variable costing income from operations will be greater than the absorption costing income from operations when units manufactured are less than the number of units sold.

Where n is the number of years of depreciation after the first year

Step-by-step explanation:

In this question, we are tasked with finding a formula which gives the taxable value T in dollars of the van after n years of depreciation.

From the question, we are told that initially, the taxable value is $28,000 but each year, there is a depreciation value of $1,900

Now since the depreciation value is constant, by multiplying the number of years by the depreciation value, we can get the amount which has been depreciated off the taxable value.

Thus, we are told that the number of years is n after the first year

The taxable value T = 28,000 - 1900(n)
