Answer: it's 30 I rook the quiz and got 100

Step-by-step explanat

Answer:

The answer is (D) y < 4

Answer:

D. y < 4 im pretty sure sorry if its wrong..

The orientation change and the symmetry across the center of rotation confirm that it is a 180° clockwise rotation. Therefore, the correct answer is D. 180° clockwise rotation.

Based on the image provided, the type of transformation shown is a 180° clockwise rotation.

A 180° clockwise rotation occurs when each point in the original shape is rotated by 180° in a clockwise direction around a fixed point. In the given image, we can observe that the original shape has been rotated by half a complete revolution, resulting in the new shape being a mirror image of the original shape but in the opposite orientation.

This transformation is evident by comparing the positions of the vertices and sides of the original shape to those of the transformed shape. The orientation change and the symmetry across the center of rotation confirm that it is a 180° clockwise rotation.

Therefore, the correct answer is D. 180° clockwise rotation.

a. Coefficient matrix A:

A = [[2, 3, 1],

[3, 3, 1],

[2, 4, 1]]

Augmented matrix [AL]:

[A|b] = [[2, 3, 1, -1],

[3, 3, 1, 1],

[2, 4, 1, -2]]

b. The resulting matrix will be [I|A^(-1)], where A^(-1) is the inverse of the coefficient matrix A.

c. The resulting vector [x1, x2, x3] represents the solution set of the system of linear equations.

a. The coefficient matrix A and the augmented matrix [A|b] for the given system of linear equations are as follows:

Coefficient matrix A:

A = [[2, 3, 1],

[3, 3, 1],

[2, 4, 1]]

Augmented matrix [AL]:

[A|b] = [[2, 3, 1, -1],

[3, 3, 1, 1],

[2, 4, 1, -2]]

b. To find the inverse of the coefficient matrix A using the Gauss-Jordan method, we perform elementary row operations until A is transformed into an identity matrix [tex][I|A^{(-1)][/tex].

Gauss-Jordan elimination steps:

Step 1: Perform row operations to convert the first column of A to [1, 0, 0]:

R1' = R1/2

R2' = R2 - (3/2)R1

R3' = R3 - R1

Step 2: Perform row operations to convert the second column of A to [0, 1, 0]:

R2'' = R2''/3

R1'' = R1'' - (3/2)R2''

R3'' = R3'' - (3/2)R2''

Step 3: Perform row operations to convert the third column of A to [0, 0, 1]:

R3''' = R3'''/2

R1''' = R1''' - R3'''

R2''' = R2''' - R3'''

The resulting matrix will be[tex][I|A^{(-1)][/tex], where [tex]A^{(-1)[/tex] is the inverse of the coefficient matrix A.

c. Once we have the inverse matrix A^(-1), we can find the solution set of the system of linear equations by multiplying A^(-1) with the augmented matrix [A|b]:

[A|b] [tex]\times[/tex] [tex]A^{(-1)[/tex] = [x1, x2, x3]

The resulting vector [x1, x2, x3] represents the solution set of the system of linear equations.

Note: To provide the numerical values for the inverse matrix [tex]A^{(-1)[/tex] and the solution set, the calculations need to be performed manually using the given coefficients of the equations.

Answer:

Quadrilateral, square, rectangle

Step-by-step explanation:

An object have parallel sides if the sides have the same distance apart and they never meet.  

Quadrilaterals usually have parallel sides

Polygons including triangles and pentagons do not have parallel sides

the sides of a quadrilateral are also perpendicular. the sides form a 90 degree angle with each other

Opposite sides of a quadrilateral are usually equal. For example, the opposite lengths of a rectangle are equal. the four sides of a square are equal

Answer:

Step-by-step explanation:

lets have the shirts represent s and the ties t.

1. 6s+3t=79.50

2. 3s+2t=41

These would be the equations.

you multiply the second equation by -2 to cancel s and add both equations.

6s+3t=79.50

-6s+-4t=-82

-1t=-2.5 (after adding you divide by -1)

t=2.5

You can then subsitute that in either equation.

I am going to ue teh second one.

3s+2t=41

3s+2(2.5)=41

3s+5=41 (subract 5 to isolate variable)

3s=36 (divide by 3 to isolate variable)

s=12

Hence, one shirt is 12$.

Answer:

  F = 3.84×10^23/R²

Step-by-step explanation:

No units are given for distance, so we cannot give a constant of proportionality that has suitable units.

The general form for inverse square variation is ...

  F = k/R²

Then the value of k can be found from ...

  k = F·R² = (6×10^5)(8×10^8)^2 = 3.84×10^23

The formula relating the given F and R is ...

  F = 3.84×10^23/R²

Answer:

2 1/3 (simplified)

Step-by-step explanation:

(1/6 - 1) = -5/6

(1 = 6/6)

(3 - 2/5) = 2 3/5

[3= 18 (3 * 6)]

(1/3 - 1/2) = -1/6

(you can change both of the denominators to 6 by multiplying them both by 3 / 2

So the equation now is

(-5/6)(2 3/5) - (-1/6)

-5/6 * 2 3/5 = 2 1/6 (simplified)

2 1/6 - -1/6 = 2 1/3 (simplified)

(assuming the. values are the shaded areas)

area = x^2 + 2x +2

perimeter = 4x + 8

Step-by-step explanation:

you have all the side except the side of the 2 squares at the top.

The squares are 1 unit on each side because the area of the 2 slender rectangles on each side is x.

So the area is x^2 + x + x + 1 + 1

The perimeter is 1+x+1+1+1+x+1+1+1+x+1+x

(starting from the lower left side and walking around the perimeter clockwise)

Answer: B

Step-by-step explanation:

The prime numbers here are outcomes 2, 3, and 5.

Therefore, we must add the frequency numbers for these prime numbers:  

                36 + 44 + 30 = 110

Out of 200 dice rolls, 110 were prime numbers. This can be represented as:

              110/200 = 11/20 (fraction form)

                             = 0.55 (decimal form)

Therefore, the answer is b. 0.55

Answer:

11.3

Step-by-step explanation:

Set up your equation:

a² + b² = c²

Plug in your values:

a² + 4² = 12²

Get a² by itself:

a² = 12² - 4²

Square your numbers and subtract:

a² = 144 - 16

a² = 128

Find the square root of both sides:

√a² = √128

a = 11.3
