Answer:

I found 8 matrices for you to choose the three you want.

Step-by-step explanation:

What are Matrices? Matrices or matrix is commonly used its mathematics, matrix, a set of numbers arranged in rows and columns to form a rectangular array. The numbers are called the elements, or entries, of the matrix. Matrices have wide applications in engineering, physics, economics, and statistics as well as in various branches of mathematics.

1. Encryption: Use to scramble data for security purposes to encode, and to decode this data we need matrices. There is a key that helps encode and decode data which is generated by matrices.

2. Games especially 3D: Use to alter an object, in 3d space. They use the 3d matrix to 2d matrix to convert it into different objects as per requirement.

3. Economics and business: Study the trends of a business, shares, and more. To create business models etc.

4. Construction: Buildings that are straight but sometimes architects try to change the outer structure. This can be done with matrices.  A matrix is made of rows and columns you can change the number of rows and columns within a matrix.  Matrices can help support various historical structures.

5. Dance – contra dance: It is used to organize complicated group dances.

6. Animation:  It can help make animations more precise and perfect.  

7. Physics: Matrices are applied in the study of electrical circuits, quantum mechanics, and optics. It helps in the calculation of battery power outputs, resistor conversion of electrical energy into another useful energy. Therefore, matrices play a major role in calculations.  Especially in solving the problems using Kirchoff’s laws of voltage and current. It helps in studying quantum physics and in using it.

8. Geology:  Matrices are used for taking seismic surveys.

-Hope this helps.

Answer:

y=-3/2x+6

Step-by-step explanation:

You can find the slope by taking two points on the graph, and making the one that occurs earlier in the graph (from left to right) the first point (x1, y1) and the one that occurs later in the graph the second point (x2, y2). The equation is m (or slope)=(y2-y1)/(x2-x1). I took the first two points in the table for this. m=(12-18)/-4-(-8)

the double negative on the bottom becomes an addition=> (12-18)/(-4+8)

the top simplifies to be -6 and the bottom simplifies to 4=>-6/4

this fraction can be reduced to -3/2, which is the slope of the graph.

Now, use point slope form (y-y1=m(x-x1)) to find the equation of the graph. Plug any coordinate on the graph in for x1 and y1 here. It should be correct as long as it is a point on the graph, but I am using the point (-8, 18) here.

=>y-18=-3/2(x-(-8))

the double negative in the parentheses becomes a positive=> y-18=-3/2(x+8)

distribute the -3/2 to every term in the parentheses=> y-18=-3/2x-12

add 18 to both sides, cancelling out the -18 on the left side of the equation=>y=-3/2x+6 (-12+18=6 to get 6 for b).

Therefore, the equation is y=-3/2x+6

Complete the square to determine the minimum or maximum value of the function defined by the expression.
FrozenT [24]

Answer:

Option D. minimum value at −38

Step-by-step explanation:

we have

x^{2}-12x-2

Let

y=x^{2}-12x-2

Complete the square

y+2=x^{2}-12x

y+2+36=(x^{2}-12x+36)

y+38=(x^{2}-12x+36)

y+38=(x-6)^{2}

y=(x-6)^{2}-38 ------> equation of a vertical parabola in vertex form

The vertex is the point (6,-38)

The parabola open upward-----> the vertex is a minimum

therefore

minimum value at −38

Solve for m.<br> 22m^2 + 7m - 2 = 0
pshichka [43]

Answer:

x= -1/2 and x=2/11

Step-by-step explanation:

Write the 7x as a difference. It'll make it easier to factor out. An example of this would be 11x-4x

Therefore, the equation would look like this: 22x^2 + 11x-4x -2 =0

Look at it as if there are two equations: 22x^2+11x and -4x-2

Factor out the greatest common factor, which is 11 from the first equation. The equation will then look like this: 11x(2x+1)

Take the GCF for the second equation as well (which is -2). The equation should then also look like this: (2x+1)

Use the numbers on the outside of each of the parenthesis to form its own equation (to factor it out). This will be 11x-2

Now we have factored! Since the parenthesis equations are the same, we know that that is also part of the equation, so:

(11x-2)(2x+1)

Solve each equation for x by equaling them both to zero
