Answer:
Yes, the dimensions will be 2x2
Step-by-step explanation:
When multiplying matrices you have AxB by CxD. You can only multiply matrices if the inner number is the same.
Ex. 2x3 by 3x2 or QxD by DxW
The dimensions of the result will depend on the outer numbers.
Ex. 2x3 by 3x2 has a 2x2 result or QxD by DxW has a QxW result
Yes, you can multiply a 2x3 matrix by a 3x2 matrix. The result will be a 2x2 matrix because the number of rows in the first matrix and the number of columns in the second matrix define the dimensions of the product matrix.
Explanation:Yes, it is possible to multiply a 2x3 matrix by a 3x2 matrix. When multiplying matrices, the number of columns in the first matrix must be the same as the number of rows in the second matrix. Therefore, in this case, where we have a 2x3 matrix and a 3x2 matrix, the 3 columns in the first matrix and the 3 rows in the second matrix make multiplication possible.
The resulting product from the multiplication of these two matrices will be a new matrix whose dimensions are determined by the number of rows in the first matrix and the number of columns in the second matrix. In this case, as the first matrix has 2 rows and the second matrix has 2 columns, the resulting matrix will have dimensions of 2x2.

Find the exact length of the third side
Answer:
c = 4.24
Step-by-step explanation:
again, you have a^2+b^2=c^2
this time, all you have to do is substitute.
3^2+3^2=c^2
9+9=c^2
18=c^2
take the square root of both sides, you get c=(18)^1/2 or about 4.24.

A circle has the equation (x+11)2+(y+6)2=324.
What are the coordinates of the center and the length of the radius?
The coordinates of the center are (11,6), and the length of the radius is 18 units.
The coordinates of the center are (−11,−6), and the length of the radius is 324 units.
The coordinates of the center are (11,6), and the length of the radius is 324 units.
The coordinates of the center are (−11,−6), and the length of the radius is 18 units.
Answer:
The centre is (-11, -6) and the radius = 18 units.
(Option 4).
Step-by-step explanation:
If we compare this with the standard form
(x - h)^2 + (y - k)^2 = r^2
- we see that the center is (-11, -6) and the radius id √324.
The center of the circle is at (−11, −6) and the radius is 18 units.
Explanation:The equation of a circle in general form is (x - h)^2 + (y - k)^2 = r^2 where (h, k) are the coordinates of the center of the circle and r is the radius. Given the equation (x + 11)^2 + (y + 6)^2 = 324, we can see that it is in a similar form but with a positive sign in the brackets. This implies that the center of the circle is at (−11, −6) and that the radius is the square root of 324, which is 18 units.

Write the first four terms of the recursive sequence: If a1=8 and an=a(n-1) -6
Is the recursive sequence arithmetic or geometric? Explain.
Answer:
8, 2, -4, -10.
Step-by-step explanation:
Each term (except the first one) is obtained by subtracting 6 from the previous one - that is what an = a(n -1) -6 means.
First term = a1 = 8 , so the second term = 8-6 = 2.
The first 4 terms are 8, 2, -4, -10.
This is an arithmetic sequence as there is a common difference of -6.

Craig bought 96 rolls or toilet paper for 48 dollars. What is the cost of a single
roll of toilet paper?
dollars
Check
Explain
HELP ME PLEASE
Final answer:
The cost of a single roll of toilet paper is $0.50, calculated by dividing the total cost of $48 by the number of rolls which is 96.
Explanation:
To find the cost of a single roll of toilet paper, we need to divide the total cost by the number of rolls. Craig bought 96 rolls of toilet paper for $48.
To calculate the cost per roll, we use the formula:
Cost per roll = Total cost / Number of rolls
So,
Cost per roll = $48 / 96 rolls
Cost per roll = $0.50 per roll
Therefore, the cost of a single roll of toilet paper is $0.50.
ms knight wants to throw a pizza party for all the 7th graders.in a random sample 13 ou of 20 7th graders preferred peperonie pizza the other 7 preferred cheeze. Based on the data out of 400 total 7th graders aproaxmently how many prefer peperoni
To estimate how many out of 400 seventh graders prefer pepperoni based on the sample, a proportion is used, resulting in approximately 260 students preferring pepperoni pizza.
Explanation:Ms. Knight wants to throw a pizza party for the seventh graders, and in a random sample, 13 out of 20 seventh graders preferred pepperoni pizza. To estimate how many out of 400 seventh graders would prefer pepperoni, we use a proportion. The proportion of students who prefer pepperoni in the sample is 13/20. To find the number who would prefer pepperoni out of 400, we set up a cross-multiplication:
13/20 = x/400Solving this equation for x (the number of 7th graders who prefer pepperoni out of 400) gives us:
20x = 13 * 40020x = 5200x = 5200 / 20x = 260So, approximately 260 seventh graders would prefer pepperoni pizza out of 400 based on the sample data.

Mrs. Henry bought books during the summer. She bought 5 books for $12.00, 6 books for $10.00, and 4 books for $8.00. What is the average (mean) amount she spent for each book?Answer options with 5 optionsA.$4.00 per bookB.$3.25 per bookC.$3.00 per bookD.$2.75 per bookE.$2.00 per book
Answer: $60.00 (5 books), $60.00 (6 books), $32.00 (4 books) is the data set. The answer, when used in a calculator, is 3.3777777777. From this result, I would say B or $3.25 per book.
The correct answer is option B) $2.75.
How to find mean?
The mean formula is given as the average of all the observations. It is expressed as Mean = {Sum of Observation} ÷ {Total numbers of Observations}.
By applying the formula
= 40/15
≅ 2.75
The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words, it is the sum divided by the count.

BC=
im not sure on how i am supposed to do this
Answer:
BC=15.01
Step-by-step explanation:
Line segment BC can also be represented by '?'. To solve for BC, find the value of '?'
Use the tangent ratio:
[tex]tangentX=\frac{opposite}{adjacent}[/tex]
Because you need the value opposite the given angle and you are given the length of the side adjacent the given angle (hypotenuse does not count as the adjacent side, EVER (btw)). Let 65° be X and let x replace'?'.Insert the appropriate values:
[tex]tan65=\frac{x}{7}[/tex]
Solve by isolating x. Multiply 7 to both sides:
[tex]7*(tan65)=7*(\frac{x}{7})\\\\7*tan65=x\\\\x=7*tan65[/tex]
Insert this equation into a calculator:
[tex]x=15.0115...[/tex]
Round to the nearest hundredth:
[tex]x=15.01[/tex]
So, BC is 15.01

I need help. Graph -4x + 4y = 1
Answer:
Step-by-step explanation:
Plz help me with this
Your answer would be the second option, (-4,5).
We can find this by substituting in each point into the equation y < |x - 3| and seeing if it is true.
For the first one you get 1 < |2 - 1|. |2 - 1| = |-1| = 1, and 1 cannot be less than itself, so this is false.
For the second one you get 5 < |-4 - 3|. |-4 - 3| = |-7| = 7, and 5 is indeed less than 7, so this is correct.
