The value of k in the equation, k over 22.8 equals 6.9, is 157.32.

The given equation is:

k / 22.8 = 6.9

In order to determine the value of k, multiply both sides of the equation by 22.8.

Multiplication is one of the basic mathematical operation. It is the operation that is used to determine the product of two or more numbers by adding a number with another number repeatedly over a number of times. The sign that represents multiplication is ×.

(k / 22.8) x 22.8 = 6.9 x 22.8

k =  157.32.

Answer:

z = 54

Step-by-step explanation:

The sum of all interior angles in a polygon is given by the formula :

(n-2) × 180  (Where n is the number of sides) .  

There are 5 sides so the sum of all interior angles will be :

(5-2) × 180 = 540°

So :

108 + 130 + 140 + 2z + z = 540

Simplify :

378 + 3z = 540

Subtract 378 from both sides :

3z = 540 - 378

3z = 162

Divide both sides by 3 :

z = 162 ÷ 3

z = 54

Answer:

x

Step-by-step explanation:

2x + 5 + 7x = 8x -11  Combine like terms

9x + 5 = 8x -11  Subtract 8x from both sides of the equation

x + 5 = -11  Subtract 5 from both sides of the equation.

x= -16

Answer: -16

Step-by-step explanation:

2x+5+7x = 8x-11 simplifies into 9x+5 = 8x -11.

Move 8x to the other side - put like terms together : 9x-8x+5 = -11

Which is simplified into x+5 = -11

Move 5 to the other side to isolate x: x = -11 -5

Combine -11 and -5

x = -16

Equation is y = 2x² + 4x + 1.

A parabola is an approximately U-shaped, mirror-symmetrical planar curve. It corresponds to a number of seemingly unrelated mathematical descriptions, all of which can be shown to define the same curves. A parabola can be described using a point and a line.

Given Data

Standard form of quadratic equation

Y = ax² +bx + c

Given points

(3,9), (30,-9). (0,1)

Equating points in formula

9= a(3)² + b(3) + c

9 = 9a + 3b +c

-9 = a(30)² + 3(30) + c

-9 = 900a + 90 + c

1 = a(0)² + b(0) + c

c = 1

Equating c in the equation

9 = 9a + 3b +1

8 = 9a + 3b

-9 = 900a + 90b +1

-10 =  900a + 90b

Multiplying both sides by 100

800 = 900a + 300b

-10    = 900a + 90b

--------------------------

790 = 210b

b = 4 (rounding off)

Putting values of b into equation

8 = 9a + 3(4)

20 = 9a

a = 2 (rounding off)

Equation is y = 2x² + 4x + 1.

If A=[-9,0,3,-1] b=[0,4,-6,2] , so the order of matrix A+B is 4x1(4 rows and 1 column).

Matrix, a set of number arranged in rows and column so as to form a rectangular array. The number are called the elements, or entries, of the matrix .

Both data and mathematical equations can be represented by the numbers in a matrix. Multiplying matrices can provide quick but accurate approximations of considerably more complex calculations in many time-sensitive engineering applications.

The elements of the matrix are nothing but the entries of the matrix.

So according, To the question we are adding matrix A which is 4 rows and 1 column to matrix B which is also of 4 rows and one column obtaining a third matrix that has also 4 rows and 1 column :

 [-9,0,3,-1]+[0,4,-6,2]=[-9,4,-3,1]

When 12 is subtracted from the square of a number and the result is 4 times the number, then the negative solution is -2

Consider the number as x

Square of the number = [tex]x^{2}[/tex]

12 subtracted from the square of a number = [tex]x^{2} -12[/tex]

4 times the number = 4x

Then the equation will be [tex]x^{2} -12=4x[/tex]

Rearrange the terms and it will become a quadratic equation

[tex]x^{2} -4x-12=0[/tex]

Split the middle term and solve the equation

[tex]x^{2} +2x-6x-12=0[/tex]

Take common terms

x(x+2)-6(x+2) = 0

Take common term outside

(x-6)(x+2) = 0

Therefore

x = 6, -2

The negative solution is -2

Hence, when 12 is subtracted from the square of a number and the result is 4 times the number, then the negative solution is -2
