A matrix is a rectangular array as well as table of characters, numbers, or expressions that is set up in rows and columns to represent a mathematical object or a characteristic of one. As an illustration, consider a matrix containing two rows as well as three columns..

In the field of optics, matrices are employed to model refraction and reflection. Quantum mechanics, electrical circuits, and resistor conversion all benefit from the usage of matrices. In electric circuits, matrices are utilized to solve equations relating to the AC network.

Step-by-step explanation:

[tex]7/10^2[/tex] is ten times [tex]7/10^3[/tex] or  [tex]7/10^3[/tex] is one-tenth of [tex]7/10^2[/tex].

[tex]10^2[/tex]  and [tex]10^3[/tex] are written in the exponent form.

Exponent

Exponent is defined as the method of expressing large numbers in terms of powers. That means, exponent refers to how many times a number multiplied by itself.

We are given two numbers [tex]7/10^2[/tex] and [tex]7/10^3[/tex].

We have to find the relationship between the two given numbers.

We know that,

[tex]7/10^2[/tex] can be written as 7/100 and [tex]7/10^3[/tex] can be written as 7/1000.

We can write,

7/1000 = (7/100) *(1/10)

Hence, 7/1000 is one-tenth of 7/100.

Also, we can write,

7/100 = (7/1000)*10

Hence, 7/100 is ten times 7/1000.

The value of the missing variable x in the given triangle is; x = 15

We know that sum of angles on a straight line is 180 degrees. That means the angle on the horizontal line of (9x + 16)° inside the triangle will be;

180 - (9x + 16)°

Now, we know that sum of angles in a triangle is 180 degrees. Thus;

180 - (9x + 16)° + 5x - 14 = 90

180 - 4x - 30 = 90

150 - 4x = 90

150 - 90 = 4x

The two other linear factors of the polynomial when it is given that k = -1 is a  zero of the given polynomial are  (x+1)(x-4)

In the above question, A cubic polynomial is given as follows

P(x) = [tex]x^{3}[/tex] - 2[tex]x^{2}[/tex] - 7x - 4

K = -1

We need to find the, linear factors of the polynomial when it is given that k = -1 is a  zero of the given polynomial

So, we got that ( x +1 ) is a one linear factor of P(x). As the highest degree of the polynomial is 3 so there will be three zeroes of the given polynomial. Therefore, We need to find others two

If we divide P(x) = [tex]x^{3}[/tex] - 2[tex]x^{2}[/tex] - 7x - 4 by ( x + 1 ) by long division method we'll get, [tex]x^{2}[/tex] -3x - 4

Now we'll solve the quotient by squaring method, to get the other two

Let's say h(x) =  [tex]x^{2}[/tex] -3x - 4

h(x) =  [tex]x^{2}[/tex] -3x - 4

h(x) =  [tex]x^{2}[/tex] -( 4 -1) x - 4

h(x) =  [tex]x^{2}[/tex] -4x + x - 4

h(x) =  x( x-4) + 1( x -4 )

h(x) =  (x+1)(x-4)

When two independent temperature readings are subtracted, or when calculating the amount of temperature rise or fall, the result is a temperature difference, also referred to as a delta temperature (T).

We are aware that throughout the course of hours, the temperature dropped from 0 to= [tex]-6\frac{3}{5}[/tex].

Therefore, we will divide the change in temperature by the number of hours to determine the rate of change of the temperature.

In order to solve for that, we shall convert the mixed number into improper fractions.

[tex]-6\frac{3}{5}=\frac{-33}{5}degrees\\ 2\frac{1}{5} =\frac{11}{5}hours\\[/tex]

Using the properties of parallel lines we find the value of x is 9 and the value of y is 13.

In geometry, parallel lines are coplanar, straight lines that never intersect.

15). In the given figure the two angles represented by 12x+1 and 15x -26 are equal. as they are alternate exterior angles.

We know from the property of parallel lines that they are equal.

Therefore:

12x+1 = 15x -26

or, 12x-15x = -26-1

or, -3x = -27

or, x = 9

Therefore the angles are 12x + 1 = 109

Now,

109 + 4y-9 +28 =180

or, 4y = 180 - 128

or, y = 13.

Therefore as the line l and m are parallel the value of x is 9 and the value of y is 13 .

Almonds are packaged 15 bags per case and walnuts are packaged 17 bags per case.

H-E-B orders no more than 200 bags of almonds and walnuts at a time.

So,

x + y < 200

where x and y refers to the number of bags

=======================================================

H-E-B pays $24 per case of almonds and $27 per case of walnuts, but will not order more than $300 total at any one time.

But keep in mind that : Almonds are packaged 15 bags per case and walnuts are packaged 17 bags per case.

So,

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions.

The initial area exists given as;

A(1) = 1/2 square meters

When it doubles every day, we have:

A(n) = 2 × A(n - 1) where A(1) = 2

So, we contain the following values

A(2) = 1/2 × 2 = 1

A(3) = 1 × 2 = 2

Answer:

Perpendicular

Explanation:

Given the coordinates

A(-2,-5), B(4.7) C(0, 2) and D(8,-2)​, we are to determine whether AB is parallel, perpendicular to CD or neither

To do this, we need to find he slope of AB and CD first. Using the formula for calculating slope as shown;

m = y2-y1/x2-x1

For AB:

slope = 7-(-5)/4-(-2)

Slope = 7+5/4+2

Slope of AB = 12/6

Slope of AB = 2

For CD

Slope of CD = -2-2/8-0

Slope of CD = -4/8

Slope of CD = -1/2

Note that for AB to be perpendicular to CD, the product of their slope must be -1.

Given

mAB = 2

mCD = -1/2

Taking their product

mAB * mCD = 2 * -1/2

mAB * mCD = -1

Since the product is -1, hence AB is PERPENDICULAR to CD

Explanation:

To find the equation with the form y = mx + b, we can use the following equation:

Where m is the slope and it is ca
