The values for the determinants of the matrices are:

|A| = -3

|B| = -2

|AB|= -6

How to determine the determinant of A, |A|?

A matrix (plural matrices) is a set of numbers arranged in rows and columns so as to form a rectangular array.

If the matrix Z is given as:

[tex]Z = \left[\begin{array}{ccc}a&b\\c&d\end{array}\right][/tex]

The determinant will be:

|Z| = (a * d) - (b * c)

Thus:

|A| = (-1 * 3) - (0 * 0) = -3

|B| = (2 * (-1)) - (0 * 0) = -2

AB = A * B

[tex]AB = \left[\begin{array}{ccc}-1&0\\0&3\end{array}\right] * \left[\begin{array}{ccc}-2&0\\0&-1\end{array}\right][/tex]  

Calculations for the product (multiply each row by each column):

[-1 * (-2)] + [0 * 0] = 2

[-1 * 0] + [0 * (-1)] = 0

[0 *  (-2)] + [3 * 0] = 0

[0 * 0] + [3 * (-1)] = -3

[tex]AB = \left[\begin{array}{ccc}2&0\\0&-3\end{array}\right][/tex]

Thus,

|AB| = (2 * (-3)) - (0 * 0) = -6

The price of a computer is $999.00. The sales tax rate is 7%. What is the sales tax on this computer in dollars and cents?

Answers

The sales tax on the computer is $69.93.

How to determine the sales tax

To calculate the sales tax on the computer, we need to multiply the price of the computer by the sales tax rate. Here's how you can do it:

Price of the computer: $999.00

Sales tax rate: 7% (which can be expressed as 0.07)

Sales tax = Price of the computer * Sales tax rate

Sales tax = $999.00 * 0.07

To find the sales tax in dollars and cents, we can perform the calculation:

Sales tax = $999.00 * 0.07

Sales tax = $69.93

Therefore, the sales tax on the computer is $69.93.

how much money deposited now will provide payment of Rs. 15000 at the end of each half year for 10 years, if interest is 16% compounded six-monthly

Answers

The amount of money that will produce Rs. 15000 at the end of 6 month for 10years at 16% is Rs. 3750

What is Compound interest?

Compound interest is the interest you earn on interest.

For example, if you have $100 and it earns 5% interest each year, you'll have $105 at the end of the first year. At the end of the second year, you'll have $110.25.

Compound interest is expressed as;

A = P( 1+r/n) ^{nt}

where A is the amount

n is the number of time its compounded

t is time

A = 15000

r = 16/100 = 0.16

n = 6/12 = 0.5

t = 10 years

15000 = P( 1 + 0.16/0.5) ^{ 0.5× 10}

15000 = P( 1 + 0.32)⁵

15000 = P( 1.32)⁵

15000 = 4P

P = 15000/4

P = Rs. 3750

Therefore the amount that will be deposited to give Rs. 15000 is Rs. 3750.

Answers

The value of sinθ is √24/7 meanwhile the correct answer is not in the option provided or perhaps option (b) is meant to be √24/7 instead.

Understanding Quadrant in Trigonometry

In the third quadrant, both the x-coordinate (cosine) and the y-coordinate (sine) of the angle are negative.

Given that

cosθ = 5/7

we can determine the value of sinθ using the Pythagorean identity:

sin²θ + cos²θ = 1

sin²θ + (5/7)² = 1

sin²θ + 25/49 = 1

Now, let's solve for sinθ:

sin²θ = 1 - 25/49

sin²θ = 49/49 - 25/49

sin²θ = 24/49

Taking the square root of both sides, we find:

sinθ = √(24/49)

Simplifying further:

sinθ = √24 / √49

sinθ = √24 / 7

Help me please answer is not A

Answers

Answer:

B) 16.47

Step-by-step explanation:

In order to find the mean of grouped data with intervals, we use the formula

(∑f * m) / (∑f)

where (∑f * m) is the sum of the product of each frequency (f) and the corresponding midpoint (m) for its interval and (∑f is the sum of each frequency

Step 1:  First, we need to find the sum of the frequencies: ∑f = 2 + 3 + 8 + 4 = 17

Step 2:  Next, we need to find the midpoint (m) of each interval.  We do this by averaging the end points of each interval

m of first interval:  (9.5 + 12.5) / 2 = 11

m of second interval:  (12,5 + 15.5) / 2 = 14

m of third interval:  (15.5 + 18.5) / 2 = 17

m of fourth interval:  (18.5 + 21.5) / 2 = 20

Step 3:  Now, we multiply the frequency for each interval by its corresponding midpoint and add them together to find the sum

f * m for first interval: (2 * 11) = 22

f * m for second interval:  (3 * 14) = 42

f * m for third interval:  (8 * 17) = 136

f * m for fourth interval:  (4 * 20) = 80

Sum of f * m for each interval:  22 + 42 + 136 + 80 = 280

Step 4:  Finally, we divide the sum of f * m for each interval by the sum of f to find the mean:

280 / 17 = 16.47058824 = 16.47

In(5400) + P X Ln30 + q X Ln360+r X Ln270
Find (P,Q,R) when they are real numbers

Pls show work

Answers

The solution for (P, Q, R) in the given equation (5400) + P x Ln30 + Q x Ln360 + R x Ln270, where P, Q, and R are real numbers, is (0, 0, 0). The correct solution is that P = Q = R = 0.

How did we get the values?

To find the values of P, Q, and R in the equation (5400) + P x Ln30 + Q x Ln360 + R x Ln270, use the properties of logarithms and solve the equation.

First, simplify the equation:

5400 + P x Ln30 + Q x Ln360 + R x Ln270

Next, express the logarithmic terms using their corresponding exponential forms:

5400 + P x Ln(30) + Q x Ln(360) + R x Ln(270)

= 5400 + P x Ln(2 x 3 x 5) + Q x Ln(2² x 3² x 5) + R x Ln(2 x 3³ x 5)

Using the properties of logarithms, we can rewrite the equation as follows:

5400 + P x (Ln(2) + Ln(3) + Ln(5)) + Q x (2 x Ln(2) + 2 x Ln(3) + Ln(5)) + R x (Ln(2) + 3 x Ln(3) + Ln(5))

Now, let's group the logarithmic terms together:

5400 + P x Ln(2) + P x Ln(3) + P x Ln(5) + Q x (2 x Ln(2) + 2 x Ln(3)) + Q x Ln(5) + R x Ln(2) + R x 3 x Ln(3) + R x Ln(5)

Simplifying further:

5400 + (P + 2Q + R) x Ln(2) + (P + 2Q + 3R) x Ln(3) + (P + Q + R) x Ln(5)

Then, the equation:

5400 + (P + 2Q + R) x Ln(2) + (P + 2Q + 3R) x Ln(3) + (P + Q + R) x Ln(5) = 0

Since this equation holds for all real numbers P, Q, and R, the coefficients of Ln(2), Ln(3), and Ln(5) must be equal to zero:

P + 2Q + R = 0 (1)

P + 2Q + 3R = 0 (2)

P + Q + R = 0 (3)

There is a system of three equations (equations 1, 2, and 3) with three unknowns (P, Q, and R). To solve this system, use any method such as substitution or elimination.

Subtracting equation (3) from equation (2), we get:

(P + 2Q + 3R) - (P + Q + R) = 0 - 0

2Q + 2R = 0

2Q = -2R

Q = -R/2 (4)

Substituting equation (4) into equations (1) and (3), we can solve for P and R:

P + 2Q + R = 0 (1)

P + (-R) + R = 0 (3)

P - R = 0

From equation (3), P = R.

Substituting P = R into equation (4):

Q = -R/2

Since P = R and Q = -R/2. Let's substitute these values back into the equations to find the final solution.

Substituting P = R and Q = -R/2 into equation (1):

P + 2Q + R = 0

R + 2(-R/2) + R = 0

R - R + R = 0

0 = 0

Equation (1) holds true for any real value of R.

Substituting P = R and Q = -R/2 into equation (2):

P + 2Q + 3R = 0

R + 2(-R/2) + 3R = 0

R - R + 3R = 0

3R = 0

R = 0

So, R = 0.

Substituting R = 0 into Q = -R/2:

Q = -R/2

Q = 0/2

Q = 0

Finally, substituting R = 0 into P = R:

P = R

P = 0

Therefore, the solution for (P, Q, R) in the given equation (5400) + P x Ln30 + Q x Ln360 + R x Ln270, where P, Q, and R are real numbers, is (0, 0, 0). The correct solution is that P = Q = R = 0.

Idaho gets out and closes the door behind her. She is in a room with one exit, and the lock requires a key. There's a table with a briefcase that is also locked. It has a three-digit combination. The first part of the combination is on a wheel with all 10 digits. The second wheel has only 5 digits, and the third has 3 digits. How many combinations are possible?

Answers

Answer:

150

Step-by-step explanation:

To determine the number of possible combinations for the briefcase, we need to multiply the number of options for each wheel.

The first wheel has 10 digits, so there are 10 possibilities.

The second wheel has 5 digits, so there are 5 possibilities.

The third wheel has 3 digits, so there are 3 possibilities.

To calculate the total number of combinations, we multiply the possibilities for each wheel:

10 × 5 × 3 = 150

Therefore, there are 150 possible combinations for the briefcase.

Answer: 150

Step-by-step explanation:

I’m not completely sure, but this is going by my logic. The first one has ten digits and any of those ten digits could go with 1 digit from the 5 wheel, and 1 digit from the 3 wheel, so (I think) you have to multiply 10x5x3 to get the amount of possible combinations.

Answers

Salina Grant's gross pay for assembling 47 chairs in one week at Chairs and More is $567.50.

To calculate Salina Grant's gross pay, we need to determine the pay for each range of chairs assembled and sum them up.

Let's break down the calculation based on the given differential piece rate scale:

1-25 chairs: $10 each

Salina assembled 25 chairs in this range, so the pay for this range is

25 * $10 = $250.

26-40 chairs: $13 each

Salina assembled 15 chairs in this range, so the pay for this range is

15 * $13 = $195.

Chairs over 40: $17.50 each

Salina assembled 47 chairs in total, and since she already assembled 25 chairs in the first range and 15 chairs in the second range, the number of chairs in this range is

47 - 25 - 15 = 7 chairs.

The pay for this range is

7 * $17.50 = $122.50.

Now, let's sum up the pay for each range to find Salina Grant's gross pay:

$250 + $195 + $122.50 = $567.50

Therefore, Salina Grant's gross pay for assembling 47 chairs in one week at Chairs and More is $567.50.

The formula for the surface area of a cylinder SA= 2mth + 2rr² is 525 cm².

To find the surface area of the cylindrical can, we need to use the formula:

SA = 2π[tex]r^2[/tex]+ 2πrh

where r is the radius of the circular base of the can, h is the height of the can, and π is a mathematical constant approximately equal to 3.14.

From the given dimensions, we know that the radius of the can is 4 cm. However, we do not have the height of the can. Therefore, we cannot accurately calculate the surface area of the can.

Based on the answer choices provided, we can approximate the surface area of the can by using the given value of r = 4 cm and an estimated value for the height.

For example, if we assume the height of the can is approximately 10 cm, then we can use the formula to calculate the surface area:

SA = 2π([tex]4^2[/tex]) + 2π(4)(10)

SA = 100.48 + 251.2

SA ≈ 351.68 [tex]cm^2[/tex]

O is the center of the regular nonagon below. Find its area. Round to the nearest tenth if necessary.

Answers

Answer:

471.1 square units

Step-by-step explanation:

A regular nonagon is a 9-sided polygon with sides of equal length.

The apothem of a regular polygon is the distance from the center of the polygon to the midpoint of one of its sides.

Therefore, the given diagram shows a regular nonagon with an apothem of 12 units.

The side length (s) of a regular polygon can be calculated using the apothem formula:

[tex]\boxed{\begin{minipage}{5.5cm}\underline{Apothem of a regular polygon}\\\\$a=\dfrac{s}{2 \tan\left(\dfrac{180^{\circ}}{n}\right)}$\\\\where:\\\phantom{ww}$\bullet$ $s$ is the side length.\\ \phantom{ww}$\bullet$ $n$ is the number of sides.\\\end{minipage}}[/tex]

Given values:

a = 12n = 9

Substitute the given values into the formula to create an expression for the side length (s):

[tex]12=\dfrac{s}{2 \tan\left(\dfrac{180^{\circ}}{9}\right)}[/tex]

[tex]12=\dfrac{s}{2 \tan\left(20^{\circ}\right)}[/tex]

[tex]s=24 \tan\left(20^{\circ}\right)[/tex]

The standard formula for an area of a regular polygon is:

[tex]\boxed{\begin{minipage}{6cm}\underline{Area of a regular polygon}\\\\$A=\dfrac{n\cdot s\cdot a}{2}$\\\\where:\\\phantom{ww}$\bullet$ $n$ is the number of sides.\\ \phantom{ww}$\bullet$ $s$ is the length of one side.\\ \phantom{ww}$\bullet$ $a$ is the apothem.\\\end{minipage}}[/tex]

Substitute the found expression for s together with n = 9 and a = 12 into the formula and solve for A:

[tex]A=\dfrac{9 \cdot 24 \tan(20^{\circ}) \cdot 12}{2}[/tex]

[tex]A=1296\tan(20^{\circ})[/tex]

[tex]A=471.705423...[/tex]

[tex]A=471.7\; \sf square\;units\;(nearest\;tenth)[/tex]

Therefore, the area of a regular nonagon with an apothem of 12 units is 471.1 square units, rounded to the nearest tenth.

side length of titles are 2ft. Rachel tiled the whole floor with 6 rows of 4 tiles
what is the area of the kitchen floor

Answers

The area of the rectangular shaped kitchen floor is A = 96 feet²

Given data ,

The side length of each tile is 2ft, then the area of each tile is:

Area of a tile = side x side = 2ft x 2ft = 4 sq ft

Since there are 6 rows of tiles, each row has 4 tiles, therefore the total number of tiles is:

Total number of tiles = 6 x 4 = 24 tiles

So, the total area covered by the tiles is:

Total area covered by tiles = Area of a tile x Total number of tiles

= 4 sq ft/tile x 24 tiles

= 96 sq ft

Hence , the area of the kitchen floor is 96 feet²

A bag consists of 5 marbles. There is 1 yellow, 1 red marble, 1 clear marble, 1 green marble, and 1 blue marble. Which table shows the sample space for choosing 2 marbles from the bag with replacement? Answer by looking at the images below!

Answers

Table C shows the sample space for choosing 2 marbles from the bag with replacement. The probabity and there are 25 possible pairs.

The sample space for choosing 2 marbles from the bag with replacement consists of all possible pairs of marbles that can be chosen, where the order in which they are chosen does not matter.

Since there are 5 marbles in the bag and we are choosing 2 of them, there are 5 choices for the first marble and 5 choices for the second marble, for a total of [tex]5*5 = 25[/tex] possible pairs.

Table C shows the sample space for choosing 2 marbles from the bag with replacement. Each row and column in the table represents a different marble that can be chosen, and each cell represents a pair of marbles that can be chosen.

For example, the cell in row 2 and column 3 represents the pair of marbles consisting of the red marble and the clear marble. Tables A and B show the sample space for choosing 2 marbles from the bag without replacement. In this case, the order in which the marbles are chosen does matter, and each marble can only be chosen once.

Therefore, there are only 5 choices for the first marble, but only 4 choices for the second marble (since one marble has already been chosen), for a total of[tex]5 * 4 = 20[/tex] possible pairs.

how do i find find the distance

Answers

The value of distance of two points shown in figure is,

⇒ d = √20

We have to given that;

Two points on graph are,

(0, 1) and (2, - 3)

Since, The distance between two points (x₁ , y₁) and (x₂, y₂) is,

⇒ d = √ (x₂ - x₁)² + (y₂ - y₁)²

Hence, The distance of two points shown in figure is,

⇒ d = √ (x₂ - x₁)² + (y₂ - y₁)²

⇒ d = √ (2 - 0)² + (-3 - 1)²

⇒ d = √4 + 16

⇒ d = √20

Thus, The value of distance of two points shown in figure is,

⇒ d = √20

Question 1 of 10
Using the graphing function on your calculator, find the solution to the system
of equations shown below.
OA. x=-8, y = 2
OB. More than 1 solution
OC. No solution
OD. x= 12, y = 3
3y-12x = 18
2y-8x = 12

Answers

The system of equations has infinitely many solutions, which corresponds to option (OB).

We can use the graphing function on a calculator to find the solution to the system of equations:

[tex]3y - 12x = 18\\\\2y - 8x = 12[/tex]

To do this, we can rearrange each equation to solve for y in terms of x:

[tex]3y = 12x + 18\\\\y =4x + 6[/tex]

For the second equation.

[tex]2y = 8x + 12\\\\y = 4x + 6[/tex]

We can see that the two equations have the same slope (4) and y-intercept (6). Therefore, the two equations represent the same line, and any point on that line will satisfy both equations.

The value of x, considering the Pythagorean Theorem, is given as follows:

x = 9.

What is the Pythagorean Theorem?

The Pythagorean Theorem states that in the case of a right triangle, the square of the length of the hypotenuse, which is the longest side,  is equals to the sum of the squares of the lengths of the other two sides.

Hence the equation for the theorem is given as follows:

c² = a² + b².

In which:

c > a and c > b is the length of the hypotenuse.a and b are the lengths of the other two sides (the legs) of the right-angled triangle.

The sides for the problem are given as follows:

15 and 8 (segment of 8 is the radius, which is the distance from the center to a point on the circumference of the circle).

Hence the hypotenuse is obtained as follows:

h² = 15² + 8²

h² = 289

h = 17.

Hence the value of x is obtained as follows:

x = 17 - 8

x = 9.
