The total number of chairs in the eight rows of the conference hall is; 144 chairs.

From the task content;

It follows that the first row contained 11 chairs and each successive row has 2 more chairs. It therefore follows from the sum of terms for an arithmetic progression that the eight rows contain;

Total number of chairs = (8/2) × (2(11) + 7(2))

In the pool, the rail of the table can be considered a rebound line as the definition suggest the table's rail can be used as a rebound line.

Water is released from the earth when it is squeezed or compacted by some force. As a further stage, the stress in the soil is removed, allowing the soil sample to expand back to its original size.

The soil will try to reclaim some of the stress it has lost after the stress has been released. Rebound is the word for this procedure.

We have a statement:

The rail of the table can be considered which of the following when making a bank shot:

The answer is a rebound line.

Answer:

The value of the x is 2 and the value of the y is 0 in the system of equation 3y=x-2, y=-2x+4.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

We have a system of the equation:

3y=x-2 ..(1)

y=-2x+4  ...(2)

From the equation (2) take the value of y and plug in the equation (1)

3(-2x+4) = x -2

-6x + 12 = x - 2

7x = 14

x = 14/7

x = 2

Plug this value in the equation (2)

y = -2(2) + 4

y = 0

Thus, the value of the x is 2 and the value of the y is 0 in the system of equation 3y=x-2, y=-2x+4.

Answer:

-252

Step-by-step explanation:

assuming that 313, 307, and 301 are the first 3 terms..

By these three numbers we can conclude that the rule is -6

(313 - x = 307, 313 - 307 = 6.. x = 6. To check this we do the same thing but with 307 and 301. 307 - x = 301, 307 - 301 = 6, 6 = x)

We find the 42nd term by multiplying our rule by the term number (42)

 -6(42) = -252 

Remember that a negative times a positive is a negative, but a negative times a negative is positive. 

The 42nd term of an arithmetic sequence is 72.

A series of integers called an arithmetic progression or arithmetic sequence (AP) has a constant difference between the terms.

Given, the sequence is an arithmetic sequence.

a₁ = 313

a₃ = 301 so n= 3

Remember that,

aₙ= a₁ + (n-1)d

aₙ=a₁+(n−1)d

301 = 313 + (3 -1)d

301 = 313 + (2d)

301 - 313 = 2d

-12 = 2d

d = -6

So to find a₄₂:

Then, use the same formula for n = 42

a₄₂ = 313 + (42 - 1) (-6)

a₄₂ = 313 - 246

a₄₂ = 72

Therefore, 72 is the 42nd term of an arithmetic sequence.

Answer:

Step-by-step explanation:

Remark

The value of the y can be found by using the Geometric Mean.  To use the said mean, you must compare parts of one triangle to parts of the second triangle. In this case, the small triangle containing boy 4 and y, must be compared to the triangle use y and 12

Formula

This translates to

4 / y = y/12

Explanation. The two triangles y and 4 and y and 12 are similar. The short side on the small right triangle on the left is 4. The second longest side on the same triangle is y.

In the triangle containing y and 12 The short side is y and the second side length is 12. You have to read this a couple of times to get the meaning of the two ratios.

Solution

4/y = y / 12                    Cross multiply

y^2 = 4 * 12

y^2 = 48                       Take the square root of both sides.

√y^2 = √48

y = √2 * 2 * 2 * 2 * 3

y = 2 * 2 * √3

Check the picture below.

The surface area of the parallelogram based prism is 1548 units squared.

The prism has 2 parallelogram base and 4 rectangular faces.

Therefore,

surface area of the prism = 2 (area of the base) + area of the 4 rectangular faces

Therefore,

surface area of the prism = 2(12 × 17) +2(19 × 13) + 2(19 × 17)

surface area of the prism = 2(204) + 2(247) + 2(323)

surface area of the prism =  408 + 494 + 646

The equation of the function g(x) is g(x) =  -x² + 4 after applying the transformation.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that:

The equation of the function f(x) = x² - 1

The equation of the function g(x) = -x² + 4

Let f(x) is the parent function.

To get the equation of the function g(x):

Applying transformation to function f(x)

f(x) → f(x) + 5 (function will shift up side by 5 units)

F(x) = x² - 1 + 5

F(x) = x² + 4

F(x) → -x²  (funtion will reflect about the line y = 4)

g(x) =  -x² + 4

Thus, the equation of the function g(x) is g(x) =  -x² + 4 after applying the transformation.

It depends on whether other opportunities are waiting. There doesn’t appear to be a trend of decrease, so it’s possible there will be more growth in the future to help cover the selling and purchase of another stock.

[tex]-\frac{1}{128}[/tex]

Step-by-step explanation:

1) Identify the type of sequence this is; whether it is geometric progression, quadratic sequence or linear sequence.

= Geometric progression

2) Find the [tex]n^{th}[/tex] term of this sequence. Every sequence of geometric progression is written in [tex]u_{n} = u_{1} * r^{n-1}[/tex] form, where [tex]u_{1}[/tex] is the first term of the sequence and [tex]r[/tex] is the common ratio. To find the [tex]n^{th}[/tex] term of this sequence, we need to find the common ratio ([tex]r[/tex]) first.

[tex]r = \frac{u_{2}}{u_{1}}[/tex]

[tex]r = \frac{-32}{64}[/tex]

[tex]r = -\frac{1}{2}[/tex]

2.1) Write it in [tex]u_{n} = u_{1} * r^{n-1}[/tex] form.

[tex]u_{n} = 64 * (-\frac{1}{2} )^{n-1}[/tex]

3) Find the [tex]14^{th}[/tex] term by substituting 14 into the [tex]n[/tex]'s.

[tex]u_{14} = 64 * (-\frac{1}{2} )^{14-1}[/tex]

[tex]u_{14} = 64 * (-\frac{1}{2} )^{13}[/tex]

[tex]u_{14} = 64 * -\frac{1}{8192}\\u_{14} = -\frac{1}{128}[/tex]

value of x = 9/2

value of y = 9√3

Cosine ratio is cos ∅ = adjacent/hypotenuse

Tangent ratio is tan ∅ = opposite/adjacent

Find x using the cosine ratio:

cos 60 = x/9

x = (cos 60)(9)

x = (1/2)(9) [cos 60 = 1/2]

x = 9/2

This question has the same problem as the other one you shared. Neither cot(32°) = 4/3 nor cos(44°) = 7/9 are true.

But if we indulge the author for a moment, we have from the double angle identity

[tex]\sin(2x) = 2\sin(x) \cos(x)[/tex]

so if x = 32°, then

[tex]\sin(64^\circ) = 2\sin(32^\circ) \cos(32^\circ)[/tex]

We also have from the Pythagorean identity

[tex]\sin^2(x) + \cos^2(x) = 1 \implies 1 + \cot^2(x) = \csc^2(x) \\\\ \implies \csc(x) = \pm \sqrt{1+\cot^2(x)} \\\\ \implies \sin(x) = \pm \dfrac1{\sqrt{1+\cot^2(x)}}[/tex]

Now, 0° < 32° < 90°, so both sin(32°) and cos(32°) are positive.

If we assume cot(32°) = 4/3 to be true, it follows that

[tex]\sin(32^\circ) = \dfrac1{\sqrt{1+\left(\frac43\right)^2}} = \dfrac35[/tex]

[tex]\cos(32^\circ) = \sqrt{1 - \sin^2(32^\circ)} = \dfrac45[/tex]

[tex]\implies \sin(64^\circ) = 2\times\dfrac35\times\dfrac45 = \dfrac{24}{25}[/tex]

so E is the only correct choice regardless of the baseless assumptions made by the question.
