We need to look at the element in the second row, second column of C, which is -3. Therefore, C₂₂ = -3.

In mathematics, a matrix is a rectangular array of numbers, symbols, or expressions arranged in rows and columns. Matrices are used to represent linear transformations, as well as to solve systems of linear equations.

A matrix with m rows and n columns is called an m x n matrix. The individual entries of a matrix are denoted by a subscript, with the first subscript indicating the row and the second subscript indicating the column. For example, the entry in the second row and third column of a matrix A would be denoted by A[2,3].

Matrices can be added, subtracted, multiplied, and divided (by a scalar). Addition and subtraction of matrices is done element-wise, while matrix multiplication involves taking the dot product of rows and columns. Multiplying a matrix by a scalar involves multiplying every entry in the matrix by that scalar.

To find B - 2A, we need to multiply every element of A by 2 and then subtract the resulting matrix from B:

2A = [(-4)*2 (-3)*2 ; (-2)*2 (-3)*2 ; (-3)2 32 ; (-2)2 42] = [-8 -6 ; -4 -6 ; -6 6 ; -4 8]

B - 2A = [6 -9 ; 7 12 ; -3 -3 ; 2 -7] - [-8 -6 ; -4 -6 ; -6 6 ; -4 8] = [14 -3 ; 11 18 ; 3 9 ; 6 -15]

So C = B - 2A = [14 -3 ; 11 18 ; 3 9 ; 6 -15]

To find C₂₂, we need to look at the element in the second row, second column of C, which is -3. Therefore, C₂₂ = -3.

Answer:

$43,200

Step-by-step explanation:

The amount of money you make a year depends on various factors, such as your monthly expenses, debt obligations, and tax liabilities.

To get a rough estimate of your annual income based on the range of affordable rent provided, you can use the rule of thumb that suggests spending no more than 30% of your gross income on housing expenses. Assuming you are willing to spend between $900 and $1080 per month on rent, we can calculate the range of annual incomes that would allow you to meet this guideline:

$900/month rent x 12 months = $10,800/year rent

$10,800/year rent / 0.3 = $36,000/year gross income

$1080/month rent x 12 months = $12,960/year rent

$12,960/year rent / 0.3 = $43,200/year gross income

Therefore, based on the assumption that you can afford rent between $900 and $1080 per month, your estimated annual gross income would need to be in the range of $36,000 to $43,200. However, this is only a rough estimate and may not take into account all of your individual financial circumstances.

Conner worked 5 hours on Monday.

Let's use the letters "m" and "f" to denote the number of hours Conner worked on Monday and Friday, respectively.

Conner worked a total of 12 hours, and since we know this from the issue statement, we may write:

m + f = 12

Also, we are aware that Conner received $81 and charged $5 on Mondays and $8 on Fridays. Hence, we can write:

5m + 8f = 81

To determine one of the variables in terms of the other, we can utilise the first equation. To solve for "f," we obtain:

f = 12 - m

We can now solve for "m" by substituting this expression for "f" in the second equation:

5m + 8(12 - m) = 81

After simplifying and finding "m," we obtain:

5m + 96 - 8m = 81

-3m + 96 = 81

-3m = -15

m = 5

Answer: A=490

Step-by-step explanation:

Formula - A = 2 ( wl + hl + hw)

2(7•14+7•14+7•7) = 490

Answer:

Since the fish is swimming down at a constant rate of 12 ft per hour for 6 hours, the distance it travels can be found by multiplying its speed by the time:

distance = speed x time

distance = 12 ft/hour x 6 hours

distance = 72 ft

We can round each figure to one decimal place to represent a percentage to the nearest tenth: Lemonade: 28%, Grape juice: 14%, Honey: 1.8% and  Sparkling water: 56.2%. So, the lemonade contributes approximately 28% to the punch mixture.

Calculate the total volume of the combination, divide it by the total volume, and then express the result as a percentage to determine the amount of each ingredient in the punch mixture.

1 quart = 4 cups

1/2 gallon = 8 cups

4 tablespoons = [tex]\frac{1}{4}[/tex] cups

So the total volume of the mixture is:

4 cups (lemonade) + 2 cups (grape juice) + [tex]\frac{1}{4}[/tex] cups (honey) + 8 cups (sparkling water) = [tex]\frac{57}{4}[/tex] cups

To show that two fractions are reciprocals, you can multiply them together and check if the product is equal to 1. That is, if we have two fractions a/b and b/a, their product is:

(a/b) * (b/a) = ab / ba = 1

Therefore, if the product of two fractions is equal to 1, they are reciprocals of each other.

For example, let's say we have the fractions 2/5 and 5/2. We can multiply them together to check if they are reciprocals:

(2/5) * (5/2) = 1

Since the product is equal to 1, we can conclude that 2/5 and 5/2 are reciprocals of each other.

To rewrite a mixed number as an improper fraction, you need to multiply the whole number by the denominator of the fraction, then add the numerator. The resulting sum is the numerator of the improper fraction, while the denominator remains the same.

For example, to rewrite the mixed number 3 1/2 as an improper fraction, you would:

Multiply the whole number 3 by the denominator 2: 3 x 2 = 6

Add the numerator 1 to the product: 6 + 1 = 7

Write the sum 7 as the numerator of the improper fraction, with the denominator 2: 7/2

So, the improper fraction equivalent of the mixed number 3 1/2 is 7/2.

Two reflections across intersecting lines have the same composition as one rotation with the junction point as the centre of rotation.

By (0,-1/2), the initial translation is provided.

Given by is the reflection along the x-axis (x,-y)

By (0,1/2), the final translation is indicated. Hence, the transformation as a whole is provided by

(x,y) → (x,-y) → (x,-y+1/2) → (x,y+1)

This demonstrates that the resulting isometry moves the values of (x,y) by one unit in the positive y-direction to (x,y+1).

The whole transformation is provided by:

P → P + (0,d/2) → Q → Q - (0,d/2)

The total transformation is given by:

P → P + (d/2,0) → (x,-y) → (x,y) → Q

where Q is positioned (x,y). Adding the two transformations together, we obtain:

P → P + (0,d/2) → Q → Q - (0,d/2) = P + (d,0)

Step-by-step explanation:

The marginal revenue when 100 units are sold is approximately $17.12. Selling one additional unit at this point would yield approximately $17.12 in additional revenue.

To find the marginal revenue, we first need to find the derivative of the total revenue function with respect to x, which is the definition of marginal revenue:

R(x) = 2200x/(ln(9x+9))

Using the quotient rule, we get:

R'(x) = (2200(ln(9x+9)) - 2200x(1/(9x+9))(1/(9x+9)))/(ln(9x+9))^2

Simplifying this expression, we get:

R'(x) = 2200(9x)/(9x+9)^2ln(9x+9)^2

Substituting x=100, we get:

R'(100) = 2200(9(100))/((9(100)+9)^2ln(9(100)+9)^2 = $9.77 (rounded to the nearest cent).

Interpretation: The marginal revenue when 100 units are sold is $9.77. This means that selling one additional unit of the product will increase the total revenue by approximately $9.77.

Answer:

Step-by-step explanation:

The first bag contains the numbers 1 through 10, which is a total of 10 numbers. The second bag contains the numbers 5 through 14, which is also a total of 10 numbers.

The probability of picking the same number from both bags is the number of ways of picking the same number divided by the total number of possible outcomes. There are 10 possible outcomes in each bag, so the total number of possible outcomes is 10 × 10 = 100.

To count the number of ways of picking the same number, we can simply count the number of numbers that appear in both bags. There are six numbers that appear in both bags: 5, 6, 7, 8, 9, and 10.

Therefore, the probability of picking the same number from both bags is:

6/100

Simplifying this fraction by dividing both the numerator and denominator by 2 yields:

3/50

So the probability of picking the same number from both bags is 3/50.

The  steps taken to design a contingency contract are valuating the potential outcomes, consequences and agree on terms of contract.

Identify the potential outcomes. Party A thinks that there is an 80% chance that the car will not break down in the first year, while Party B thinks that there is an 80% chance that it will. These are the two potential outcomes that need to be identified.

Determine the consequences of each outcome. Next, the consequences of each outcome should be determined. For example, if the car breaks down in the first year, then Party A may have to pay for repairs or reimburse Party B for the purchase price of the car. If the car does not break down, then no consequences need to be determined.

Agree on the terms of the contract. Finally, both parties need to agree on the terms of the contract. This may include how much Party A will have to pay if the car breaks down, how long Party B has to wait for reimbursement if the car does break down, and any other terms that are relevant to the situation. Once the terms have been agreed upon, the contingency contract can be signed by both parties, and they can proceed with the sale of the car.

A contingency contract could be designed to help them avoid an impasse over the issue of the car's breakdown. The contingency contract is a contract that is triggered by a specific event or circumstance, such as the car breaking down in the first year. This contract outlines what will happen if the event or circumstance occurs, and both parties agree to the terms in advance.
