The inverse of a matrix is a matrix that, when multiplied by the original matrix, results in the identity matrix. To find the inverse of the given matrix [1 -1 0 -4 2 -1 4 3 3], we need to use the following steps:

Step 1: Find the determinant of the matrix. The determinant of a 3x3 matrix is given by:

|A| = a(ei - fh) - b(di - fg) + c(dh - eg)

where a, b, c, d, e, f, g, h, and i are the elements of the matrix. Plugging in the values from the given matrix, we get:

|A| = (1)(2*3 - (-1)*3) - (-1)(-4*3 - 0*4) + (0)(-4*(-1) - 2*4)

|A| = (1)(6 + 3) - (-1)(-12) + (0)(4 - 8)

|A| = 9 - 12 + 0

|A| = -3

Step 2: Find the matrix of minors. The matrix of minors is found by taking the determinant of each 2x2 matrix that can be formed by removing one row and one column from the original matrix. The matrix of minors for the given matrix is:

[(-1)(3) - (-1)(3)  (0)(3) - (-1)(4)  (0)(3) - (-1)(-4)]
[(-4)(3) - (2)(3)   (1)(3) - (0)(4)   (1)(-4) - (0)(2) ]
[(-4)(-1) - (2)(0)  (1)(0) - (-1)(-4) (1)(2) - (-1)(-4)]

= [0  4  4]
 [-6 3 -4]
 [4 -4 -2]

Step 3: Find the matrix of cofactors. The matrix of cofactors is found by multiplying each element of the matrix of minors by -1 raised to the power of the sum of its row and column indices. The matrix of cofactors for the given matrix is:

[0  -4  4]
[6  3  -4]
[-4 4  -2]

Step 4: Find the adjugate matrix. The adjugate matrix is found by taking the transpose of the matrix of cofactors. The adjugate matrix for the given matrix is:

[0  6  -4]
[-4 3  4]
[4  -4  -2]

Step 5: Find the inverse matrix. The inverse matrix is found by dividing each element of the adjugate matrix by the determinant of the original matrix. The inverse matrix for the given matrix is:

[0/(-3)  6/(-3)  -4/(-3)]
[-4/(-3) 3/(-3)  4/(-3)]
[4/(-3)  -4/(-3)  -2/(-3)]

= [0  -2  4/3]
 [4/3  -1  -4/3]
 [-4/3  4/3  2/3]

Therefore, the inverse of the given matrix [1 -1 0 -4 2 -1 4 3 3] is:

[0  -2  4/3]
[4/3  -1  -4/3]
[-4/3  4/3  2/3]

Given line: y = -2x + 6 and Perpendicular line: y = 2x - 6: The slope of the given line is -2 and the slope of the perpendicular line is 2. Both slopes are in simplest form.

Slope is a measure of the steepness or inclination of a line, or a rate of change. It is usually represented by the letter m, and is calculated by finding the ratio of the rise (vertical change) over the run (horizontal change) between two points on a line. Slope can also be used to describe the angle of a line or surface, which is usually expressed as a percentage or in degrees. In mathematics, slope is used to describe the behavior of a line or curve, as well as to compare lines or curves with different slopes.

Answer:

The slope of the given line on the graph is 1/3.

Answer:

1/3

Step-by-step explanation:

The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).

Let's start at 0 with x = 0 and y = 0 or (0,0)

You see the graph crosses coordinate (3,1)

so y goes from 0 to 1 => rise = 1

x goes from 0 to 3 => run = 3

then rise/run = 1/3

The length of line LN is 25.

What is Similarity of Triangles?

Two triangles are similar if they have the same shape but possibly different sizes. This means that their corresponding angles are congruent and their corresponding sides are proportional.

Since line MN is parallel to line JK, we can use the property that corresponding angles are congruent to set up the following proportion:

LN/KJ = NM/JK

Substituting the given values, we have:

LN/40 = 25/40

Multiplying both sides by 40, we get:

LN = 25

Therefore, the length of line LN is 25.

The standard deviation of the sample is 24. Therefore the correct option is, option b. 24.


The variance of a sample is the square of the standard deviation. In other words, the standard deviation is the square root of the variance. Therefore, to find the standard deviation of the sample, we need to take the square root of the variance:
√576 = 24

Standard Deviation is a measure which shows how much variation (such as spread, dispersion, spread,) from the mean exists. The standard deviation indicates a “typical” deviation from the mean. It is a popular measure of variability because it returns to the original units of measure of the data set.

Like the variance, if the data points are close to the mean, there is a small variation whereas the data points are highly spread out from the mean, then it has a high variance.

So, the standard deviation of the sample of 169 observations and variance 576 equals 24. The correct option is b.

The given sequence is A(n) = 6.3 + (n-1)(5), where n is the term number. To find the 5th term of the sixth term of the sequence, we need to first find the value of the sixth term and then find its fifth term.

To find the sixth term of the sequence, we substitute n = 6 in the given formula:

A(6) = 6.3 + (6-1)(5)

A(6) = 6.3 + 25

A(6) = 31.3

Now, to find the fifth term of this sequence, we need to go back one term from the sixth term, which means we need to substitute n = 5 in the original formula:

A(5) = 6.3 + (5-1)(5)

A(5) = 6.3 + 20

The value of r is approximately 0.62.

The sum of the first 3 terms of a geometric sequence is 30 1/2 and the sum of the 4th, 5th, and 6th term is 3 15/16. To determine the value of r, we can use the formula for the sum of a geometric sequence:

S_n = a_1 (1 - r^n) / (1 - r)

Where S_n is the sum of the first n terms, a_1 is the first term, and r is the common ratio.

For the first 3 terms, we have:

30 1/2 = a_1 (1 - r^3) / (1 - r)

For the 4th, 5th, and 6th terms, we can use the formula for the nth term of a geometric sequence:

a_n = a_1 r^(n-1)

So the 4th term is a_1 r^3, the 5th term is a_1 r^4, and the 6th term is a_1 r^5. The sum of these terms is:

3 15/16 = a_1 r^3 + a_1 r^4 + a_1 r^5

We can factor out a_1 r^3 to get:

3 15/16 = a_1 r^3 (1 + r + r^2)

Now we can substitute the expression for a_1 r^3 from the first equation into the second equation:

3 15/16 = (30 1/2) (1 - r) (1 + r + r^2)

Simplifying and rearranging terms, we get:

r^5 - 8r^4 + 15r^3 - 8r^2 + r = 0

This is a quintic equation, which cannot be solved algebraically. However, we can use numerical methods to find an approximate value of r. Using a graphing calculator, we find that r ≈ 0.62.

Therefore, the value of r is approximately 0.62.

A milkshake costs $3.50 and an ice cream sundae costs $4.75.

A system of linear equations is a set of two or more linear equations that contain the same variables. A linear equation is an equation of a straight line and has the form ax + by = c, where a, b, and c are constants and x and y are variables.

The goal of a system of linear equations is to find the values of the variables that satisfy all the equations in the system simultaneously. This can be done by different methods, such as substitution, elimination, or matrix methods.

Systems of linear equations are widely used in mathematics, science, engineering, and economics to model and solve real-world problems involving multiple unknowns. They are a fundamental concept in algebra and linear algebra.

Using this information, we can set up a system of equations to find the cost of a milkshake and the cost of an ice cream sundae. Let's use x to represent the cost of a milkshake and y to represent the cost of an ice cream sundae.

From the first sentence, we can write the equation:

[tex]4x + 2y = 23.5[/tex]

From the second sentence, we can write the equation:

[tex]8x + 6y = 56.5[/tex]

Now we can solve for x and y using any method of solving systems of equations, such as substitution or elimination.

Let's use elimination. Multiplying the first equation by -3 and adding it to the second equation, we get:

[tex]-12x - 6y = -70.5[/tex]

[tex]8x + 6y = 56.5[/tex]

[tex]-4x = -14[/tex]

Dividing both sides by -4, we get:

[tex]x = 3.5[/tex]

Now we can substitute x = 3.5 into one of the original equations to solve for y. Let's use the first equation:

[tex]4x + 2y = 23.5[/tex]

[tex]4(3.5) + 2y = 23.5[/tex]

[tex]14 + 2y = 23.5[/tex]

[tex]2y = 9.5[/tex]

[tex]y = 4.75[/tex]

Therefore, a milkshake costs $3.50 and an ice cream sundae costs $4.75.

Step-by-step explanation:

Let's start by setting up a proportion to represent the ratio of black tiles to white tiles:

1 black tile : 4 white tiles

We know that Eddie wants a total of 25 tiles in the design, so we can set up another proportion to represent the ratio of white tiles to the total number of tiles:

white tiles : 25 total tiles

To solve for the number of white tiles, we need to find the equivalent ratio of white tiles in terms of the total number of tiles. We can do this by cross-multiplying our two proportions:

1 black tile * (white tiles/4 black tiles) = white tiles/4

white tiles/25 total tiles = (white tiles/4) / (1 black tile + white tiles/4)

Simplifying this expression, we get:

white tiles/25 = (white tiles/4) / (5/4)

white tiles/25 = (1/4) * (white tiles/5)

5 * white tiles = 100

white tiles = 20

Therefore, Eddie will use 20 white tiles in his design.

The total materials purchase usage variance is -P122.50.

The total materials cost variance is calculated by subtracting the total standard cost from the total actual cost. The total standard cost is P675.00 per batch and there were 14 batches produced during the month, so the total standard cost is P675.00 x 14 = P9,450.00. The total actual cost is calculated by multiplying the quantity purchased by the purchase price for each fruit and then adding them all together. The total actual cost is (300 x P9.50) + (150 x P22.00) + (350 x P7.20) + (80 x P15.40) = P2,850.00 + P3,300.00 + P2,520.00 + P1,232.00 = P9,902.00. The total materials cost variance is P9,902.00 - P9,450.00 = P452.00.

The materials yield variance is calculated by subtracting the standard quantity of materials from the actual quantity of materials used and then multiplying by the standard cost per liter. The standard quantity of materials is 60 liters per batch and there were 14 batches produced during the month, so the standard quantity of materials is 60 x 14 = 840 liters. The actual quantity of materials used is 290 + 130 + 350 + 75 = 845 liters. The materials yield variance is (840 - 845) x P10.00 = -P50.00.

The materials purchase usage variance is calculated by subtracting the standard cost per liter from the actual cost per liter and then multiplying by the actual quantity of materials used. The materials purchase usage variance for each fruit is (P9.50 - P10.00) x 290 + (P22.00 - P21.25) x 130 + (P7.20 - P7.50) x 350 + (P15.40 - P15.00) x 75 = -P145.00 + P97.50 - P105.00 + P30.00 = -P122.50.

The measure of arc ED is 78.7°

An arc of a circle is a portion of the circumference of a circle. It is defined by two endpoints and the arc itself.

The measure of an arc is given in degrees or radians, and it is determined by the angle that it subtends at the center of the circle.

Since FC is the diameter and arc FB is equivalent to arc BC. We can say:

arc FB + arc BC = 180°

arc FB = arc FB = 90°

Also, arc ED is twice the measure of arc CD. We can write:

arc ED = 2 * arc CD

arc CD =  (arc ED)/2

Since the sum arc FB and arc BC is 180°. We can say:

arc FE + arc ED + 0.5(arc ED) = 180°

62° + arc ED + 0.5(arc ED) = 180°

Simplifying the equation, we get:

0.35x + x = 5.4 ÷ 0.5

0.35x + x = 10.8

1.35x = 10.8

x = 8

So, Daniel bought 8 apples, which means he also bought 2x = 16 oranges.

However, we need to check if this solution makes sense hence the cost of the apples would be:

0.35 × 8 = 2.8

And the cost of the oranges would be:

0.5 × 16 = 8

Adding those together, we get:

2.8 + 8 = 10.8

Answer:

Since the hexagon is a 2D shape, it does not have volume. We can find the area of a hexagon but not its volume.

Step-by-step explanation:

The ratio of the areas of two similar figures is equal to the square of the ratio of their corresponding side lengths. In this case, since the figures are hexagons, we can use the ratio of their corresponding side lengths to find the ratio of their areas.

Since the scale factor of the hexagons is 3:7, we know that the ratio of their side lengths is also 3:7. Therefore, the ratio of their areas is:

(3/7)^2 = 9/49

We are given that the area of the smaller hexagon is 18 m^2, so we can use this to find the area of the larger hexagon:

(area of larger hexagon) = (area of smaller hexagon) x (ratio of areas)

(area of larger hexagon) = 18 x (9/49)

(area of larger hexagon) = 3.28 m^2 (rounded to two decimal places)

Since the hexagon is a 2D shape, it does not have volume. We can find the area of a hexagon but not its volume.

The expression for the height of the box is 3x^(1)y^(-1)z^(1) units.

The volume of a rectangular box is given by the formula V = lwh, where l is the length, w is the width, and h is the height. We are given the volume, width, and length of the box and we are asked to find the expression for its height.

Volume = 60x^(6)y^(6)z^(10)
Width = 2x^(2)y^(3)z^(4)
Length = 10x^(3)y^(4)z^(5)

Substituting the given values into the formula for volume, we get:

[tex]60x^{(6)}y^{(6)}z^{(10)} = (2x^{(2)}y^{(3)}z^{(4))}(10x^{(3)}y^{(4)}z^{(5))(h)[/tex]

Simplifying the right side of the equation, we get:

60x^(6)y^(6)z^(10) = 20x^(5)y^(7)z^(9)(h)

Dividing both sides of the equation by 20x^(5)y^(7)z^(9), we get:

h = (60x^(6)y^(6)z^(10))/(20x^(5)y^(7)z^(9))

Simplifying the fraction, we get:

h = 3x^(1)y^(-1)z^(1)

Therefore, the expression for the height of the box is 3x^(1)y^(-1)z^(1) units.

Answer:

The range stays 48°

Step-by-step explanation:

The range is the difference between the highest and lowest values in the data set. Before adding 80.2°, the highest temperature is 105° and the lowest temperature is 57°, so the range is 105° - 57° = 48°.

After adding 80.2°, the highest temperature becomes 105° + 80.2° = 185.2° and the lowest temperature becomes 57° + 80.2° = 137.2°. So the new range is 185.2° - 137.2° = 48°.

Therefore, the range stays the same at 48°. The answer is: The range stays 48°.
