Explanation:

The magic square is a n×n square which contains different number and sum of all the number of any row or column gives same value.

in any magic square the sum values of all row or column is three time of the number in centre of the square.

in above magic square the middle number is 2/6

so we can calculate the final value by multiplying with 3,

[tex] \frac{2}{6} \times 3 = \frac{2}{ \cancel6}_2 \times \cancel3 = \cancel{\frac{2}{2}} = 1[/tex]

The magic number or sum of any row or column is 1,

using this we can find the missing,

in column first,

1/6 and 1/3 are given and middle term is missing

let the middle term be x now,

[tex]x + \frac{1}{6} + \frac{1}{3} = 1 \\ x = 1 - \frac{1}{6} - \frac{1}{3} \\ x = 1 - ( \frac{3 + 6}{18}) \\ x = 1 - \frac{9}{18} \\ x = \frac{18 - 9}{18} \\ x = \cancel \frac{9}{18} = \frac{1}{2} [/tex]

similarly we can solve for the 3rd fraction of second column,

let the third number be y,

[tex] \frac{3}{ 6} + \frac{2}{6} + y = 1 \\ y = 1 - \frac{3}{ 6} - \frac{2}{6} \\ y = 1 - \frac{5}{6} = \frac{1}{6} [/tex]

Now in first and third row, the third number is missing which can be calculated in same way.

The rough work and final calculation is attached!

Answer:

  D) the point where the graph crosses the y-axis

Step-by-step explanation:

The "initial" value of a function is generally taken to mean the function value when the independent variable is zero.

On a graph of the profit function, that will be the y-intercept: the point where the graph crosses the y-axis.

__

The highest point on the graph will be the maximum profit.

The points where the graph crosses the x-axis will be where profit is zero, referred to as "break-even" points.

The lowest point on the graph will be where the profit is a minimum. That point may actually indicate a loss (negative profit).

Step-by-step explanation:

Use the distributive property.

First, multiply by expand.

⇒ -4(2a+3)

⇒ -4*2a=-8a

⇒ -4*3=-12

⇒ -8a-12

→ 6a-8a-12

Solve.

Add or subtract the numbers from left to right.

⇒ 6a-8a=-2a

= -2a-12

[tex]\Longrightarrow: \boxed{\sf{-2a-12}}[/tex]

Answer:

  ST = 6

Step-by-step explanation:

The segment sum is ...

  QR +RS +ST = QT

  QR +2 +ST = 10 . . . . use given values

Since R is the midpoint of QS, we know QR = RS = 2. Now, we have ...

  ST = 10 -2 -QR = 10 -2 -2 = 6

The length of ST is 6.

Answer:

140 degrees

Step-by-step explanation:

The formula of the hint is the sum of the angles in a nonagon (9 sided polygon). If we divide the sum of the angles in a nonagon by nine we should be able to get the angle of each nonagon.

(9-2) * 180 = 7 * 180 = 1260

1260/9 = 140 degrees

The tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base. The Height of the fence is 8 feet.

The tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base. it is given as,

tan(θ) = Perpendicular/Base

where,

θ is the angle,

Perpendicular is the side of the triangle opposite to the angle θ,

Base is the adjacent smaller side of the angle θ.

Given that a 25-foot tree casts a 6 1/4-foot shadow. Also, At the same time, a fence casts a 2-foot shadow.

Length of the shadow = 6 1/4 feet = 6 + 1/4 = 6.25 feet

Now, since the sun is at the same angle, therefore, the angle between the top of the object and the top of the its shadow will be the same for all the objects. Therefore,

tan(θ) = Height of the tree/Shadow of the tree = Height of the fence/Shadow of the fence

tan(θ) = 25 feet / 6.25 feet =  Height of the fence / 2 feet

Height of the fence = (2feet × 25 feet) / 6.25 feet

Height of the fence = 8 feet

Hence, the Height of the fence is 8 feet.

Answer:

9 + x + x + 2 = 29

Step-by-step explanation:

all of the sides added together is 29

so

9 + x + x + 2 = 29

that is your equation

Well, at first consider the given equation, then will be solving for Part A) and B),

[tex]{:\implies \quad \sf 5+x-14=x-7}[/tex]

Subtracting x from both sides will yield ;

[tex]{:\implies \quad \sf 5-14=-7}[/tex]

[tex]{:\implies \quad \sf -9=-7}[/tex]

But, -9 ≠ -7, so their is no solution for values of x, as -9 can't be equal to -7 , so from definition of algebra, we can say that, their are no solutions for x, as there are no solutions for x, so nothing can be concluded from Part A and Part B

Answer:

Part A: -9 ≠ -7

no solution

Part B: below for the answers

Step-by-step explanation:

Part A: 5 + x - 14 = x - 7

subtract x on both sides

x - 5 + x - 14 = x - 7 - x

then, we take away the x's

5 - 14 = -7

-9 ≠ -7

there is no solution

Part B: 5 + -2 - 14 = -2 - 7

-11 ≠ -9

5 + 0 - 14 = 0 - 7

-9 ≠ -7

5 + 3 - 14 = 3 - 7

-6 ≠ -4

This then means,

[tex]\cos^4 A + \cos^2 A = 1\\\\\sin^2 A + \cos^2 A = 1\\\\[/tex]

which is the pythagorean trig identity. This concludes the proof.

Therefore, if [tex]\cot^4 A - \cot^2 A = 1[/tex], then [tex]\cos^4 A + \cos^2 A = 1[/tex]

[tex]y = 3x +1[/tex]

Step-by-step explanation:

We can verify it by substituting the [tex]x[/tex] with the numbers in the [tex]x[/tex] column to get the same [tex]y[/tex] in the [tex]y[/tex] column.

Check:

[tex]y = 3(-2) +1\\y = -6 +1\\y= 5[/tex]

It matches; therefore, the answer is [tex]y = 3x +1[/tex]. You can try with the other equations given and take the same steps, but it will not match.
