whatre the values of x and y

The inverse of a matrix A is A^-1. And I, the identity matrix, is equal to A.A^-1.

The square matrix needs to be non-singular and have a non-zero determinant value in order to get the inverse matrix. Let's think about the 2 x 2 square matrix A.

Inverse of  matrix:

A^(-1)=Adj A/|A|

A-1 stands for Inverse of Matrix for matrix A. There is a straightforward formula for calculating the inverse of a 2 × 2  matrix. In order to find the inverse of a matrix of order 3 or higher, we also need to be aware of the matrix's determinant and adjoint. When multiplied by the provided matrix, the other matrix that serves as the inverse of that matrix yields the multiplicative identity.

There are two ways to find a matrix's inverse. Through the use of an adjoint of a matrix and simple processes, it is possible to derive the inverse of a matrix. Row or column transformations can be used to carry out the basic operations on a matrix. Additionally, the adjoint and determinant of the matrix can be used to apply the inverse of matrix formula in order to get the inverse of a matrix.

Step-by-step explanation:

The shorter side of the rectangle is 18 feet.

Perimeter of a rectangle = 2(l + w), where w is the width of the rectangle and l is its length.

Given the following:

Another side of the rectangle = width = w

One side of the rectangle = length = 3w - 9

Perimeter of the rectangle = 126 feet

Therefore:

2(3w - 9 + w) = 126

2(4w - 9) = 126

8w - 18 = 126

8w = 126 + 18

8w = 144

8w/8 = 144/8

w = 18

One side of the rectangle = 3w - 9 = 3(18) - 9 = 45

Therefore, the shorter side of the rectangle is 18 feet.

The smallest integer value of x for which angle A would be classified as obtuse is 14°

An obtuse angle can be defined as an angle that is greater than 90 degrees.

This can be expressed as;

Obtuse angle > x > 90°

Given the angle as A = 5x +29

Let's assume that the value of the obtuse angle is 99 which is greater than 90 degrees.

Now, we have to equate the expression for angle A to 91 degrees.

We have;

5x + 29 = 99

collect like terms

5x = 99 - 29

subtract like terms

5x = 70

To make 'x' the subject, divide both sides by the coefficient of x

5x/5 = 70/5

x = 14°

Thus, the smallest integer value of x for which angle A would be classified as obtuse is 14°

The coordinates of the point 3/10 of the way from a to b is (-0.3, -6.3)

The given parameters are:

The position of the point is given as:

Location = 3/10

Express as ratio

m ; n = 3 : 10 - 3

This gives

m ; n = 3 : 7

The coordinates of the point are then calculated as:

Point = Location * (mx2 + nx1, my2 + ny1)

This gives

Point = 3/10 * (3 * 9 + 7 * -4, 3 * 7 + 7 *  -6)

Evaluate

Point = 3/10 * (-1, -21)

This gives

Point =  (-0.3, -6.3)

8,615-4,229=4386 Answer took the quiz!

Answer:

4386

Step-by-step explanation:

8615-4229

= (8000 + 600 + 10 + 5) - (4000 + 200 + 20 + 9)

= (8000-4000) + (600-200) + (10-20) + (5-9)

= 4000 + 400 + (-10) + (-4)

= 4000 + 300 + (100-10) + (-4)

= 4300 + 80 + (10-4) = 4386

The weight of the spaceship that has a mass of 9000kg is 22936kg.

It should be noted that the mass in a body simply means the measure of the quantity if the matter that the body has.

It should be noted that it is also the body of the inertia.

In this case, the spaceship has a mass of 9000kg. The spaceship is launched from Earth and lands on a distant planet, where it has a gravity of 25 m/s². Therefore, the weight will be:

= 9000 /9.81 × 25

= 22936kg

Therefore, the weight of the spaceship that has a mass of 9000kg is 22936kg.

Answer:

Here is the answer, let me know if I did it wrong.

Answer:

IK = 13 and x = - 12

Step-by-step explanation:

Let's write down each segment and if available express it in terms of x which has to be determined in order to find length of segment IK

We have IK = x + 25 (to be determined)

JK = 2x + 30     (1)

KL (unknown)

IL = x + 34      (2)

JL = 15            (3)

The entire segment

IL = IJ + JL

Substituting for JL = 15 we get IL = IJ + 15

But we are given IL = x + 34

IJ + 15 = x + 34

IJ = x + 34 -15 = x + 19   (4)

IK = IJ + JK

Substituting for IJ = x + 19 from equation (4) and JK = 2x + 30 from equation (1) we get IJ + IK = x + 19 + 2x + 30 = 3x + 49

But we are given that IK = x + 25

So

3x + 49 = x + 25

Moving x from the RHS to the LHS and 49 from the LHS to the RHS we get

3x-x = 25 - 49

2x = -24

x = -12

IK = -12 + 25 = 13

We can verify this by finding the lengths of each segment and seeing they are consistent

We have

IJ = x + 19 = -12 + 19 = 7

JK = 2x + 30 = 2(-12) + 30 = -24 + 30 = 6

IL = x + 34 = -12 + 34 = -23

We also have the fact that JK + KL = JL = 15

Substituting for JK we get

6 + KL = 15

KL = 15-6=9

Total segment length = 7+6 + 9 = 22

x + 34 = -12 + 34 = 22

So it is consistent

The reflection of Z (5 1/2, 3) across the x-axis is (5 1/2, -3).

Here,

The given point is Z (5 1/2, 3).

We have to find the point of reflection of Z (5 1/2, 3) across the x-axis.

What is Reflection across x-axis?

A point after reflection across the x-axis, the x- coordinate remains the same but y - coordinate is taken to be the additive inverse.

Now,

Since, The given point Z (5 1/2, 3) is lie on first coordinate.

Hence, The reflection of the point Z (5 1/2, 3) is lie on the third coordinate.

And, In the third coordinate the x-coordinate is positive and y-coordinate is negative.

Since, The rule of the reflection across x- axis is,

(x, y) → (x, -y)

So, The reflection of the point Z (5 1/2, 3) across the x - axis = (5 1/2, -3)

Therefore, The reflection of Z (5 1/2, 3) across the x-axis is (5 1/2, -3).

The given expression is a*(b*c).

The associative property is holds for multiplication.

According to the definition of associative property when more than two numbers are multiplied the result remains the same, irrespective of how they are grouped.

The equivalent expression for a*(b*c) is (a*b)*c.

For example a=2,b=3 and c=1 then

a*(b*c) =2*(3*1)=6
