I cannot give a thorough explanation but I will show my workings and reasoning.

Reasoning:

Vertically opposite angles are equal

Angles in a triangle add up to 180 degrees

Workings:

35 multiplied by 2 is 70

70 add 90 is 160

180 minus 160 is 20

x = 20

Answer:

Answer:

26π cm

Step-by-step explanation:

the circumference (C) of a circle is calculated as

C = πd ( d is the diameter )

   = π × 26

   = 26π cm

▶︎◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◀︎

[tex]Hello[/tex] [tex]There![/tex]

 We are looking for the circumference of the circle.

It's not hard, I promise! I will take you through a few steps, and we'll find the answer.

Are you ready? Then let's begin...:)

[tex]Procedure:[/tex]

First, we need a formula for the circumference. We can't find the circumference without a formula!

· Luckily, there is a formula for the circumference:

⇒ [tex]C=\pi d}[/tex]

Whoa. What's that?!

No worries, I'll clarify everything in a moment. :)

We are looking for the circumference.

In this formula, what stands for the circumference?

That's right, [tex]C[/tex].

Now, what is this: [tex]\pi[/tex]?

This letter stands for pi - a constant in maths that comes in handy when we're searching for the circumference of a circle (or area).

It has an infinite number of digits after the decimal point, and these digits never repeat!

You might be thinking, "Oh no! Are we really going to use that infinite number?!"

The answer is "No". Mostly, we use 3.14 for [tex]\pi[/tex], because these are the first three digits of pi, but since we aren't asked to use 3.14 for pi, we just press the [tex]\boxed{\pi }[/tex] button on our calculator.

Whew!

And then last but not least, we see "d". This isn't a constant, this is the diameter.

Checking our provided information, we see that the diameter is 26 cm.

Now, we substitute 26 for d:

[tex]\bold{C=\pi (26)}[/tex]

[tex]\bold{C=\pi *26}[/tex]

And now all we have to do is type these numbers into our calculator, and find the answer:

[tex]\bold{C\approx81.7\:cm}[/tex]

Hooray! We've found the circumference!

But wait - why isn't 81.7 an option?

Because what we need to do is write it in terms of pi, which is even easier, because we just substitute 26 for d:

[tex]\bold{C=\pi *26}[/tex]  

➢ Rearrange the order of the terms:

[tex]\bold{C=26\pi \:cm}[/tex]

▲ Circumference

Now there's another thing - why are all four options with units squared?

Circumference isn't measured in units squared, the area is!

▶︎ Incase you need the area, here it is:

[tex]\bold{A=\pi r^{2}}[/tex]

A=Area (what we're looking for)

[tex]\pi[/tex] = pi

Here we have a new variable - it's r, which is the radius.

Do you see that [tex]^2[/tex] next to r? It means that r is squared, or multiplied by itself.

You might be thinking, "But we don't have the radius!"

If we have the diameter, finding the radius is a piece of cake, because we divide the diameter by 2:

[tex]\bold{26\div2}[/tex]

[tex]\bold{13}[/tex]

Now we substitute 13 for r and evaluate:

⇒ [tex]\bold{A=\pi (13)^{2}}[/tex]

13 times itself is 169:

⇒ [tex]\bold{A=169\pi \:cm^{2}}[/tex]

Whew! We're finally done!

[tex]Greetings![/tex]

It is required to find the sum of the terms from 2 (the bottom number of sigma) through 29 (the top number of sigma)

The number of terms is

The sum of the first 28 terms is

Answer:

114,126 (nearest whole number)

Step-by-step explanation:

Geometric sequence

General form of a geometric sequence: [tex]a_n=ar^{n-1}[/tex]

(where a is the first term and r is the common ratio)

Given:

[tex]\displaystyle \sum^{29}_{n=2}80(1.23)^{n-2}[/tex]

The sigma notation means to find the sum of the given geometric series where the first term is when n = 2 and the last term is when n = 29.

First term (a)

Determine the first term by substituting n = 2 into the given expression:

[tex]n=2 \implies 80(1.23)^{2-2}=80[/tex]

Common ratio (r)

From inspection, the common ratio is 1.23.

nth term

As the first term is when n = 2 and the last term is when n = 29, there is a total of 28 terms.

Therefore:

Sum of the first n terms of a geometric series:

[tex]S_n=\dfrac{a(1-r^n)}{1-r}[/tex]

Substituting the given values into the formula:

[tex]\implies S_{28}=\dfrac{80\left(1-1.23^{28}\right)}{1-1.23}=114125.7556[/tex]

Therefore, the sum of the given geometric series is 114,126 (nearest whole number)

Answer:

Answer:

(2) B

Step-by-step explanation:

According to the graph

p(2, 3) so (-b, a) is (-3, 2)

So B is right

Answer:

[tex]B = ( - b,\: a)[/tex]

Step-by-step explanation:

Since P has the coordinates (a, b), then (a,b) would be (2, 3). Therefore:

[tex]a = 2\: and \: b = 3[/tex]

We are trying to find what point has the coordinates (-b, a). Recall:

[tex]a = 2 \: \: \: \: \: \: \: \: b = 3 \\ ( - b, \: a) = \\ ( - 3, \: 2)[/tex]

The point that is at (-3, 2) is point B.

The range is found by subtracting the smallest data value from the largest data value. Here, the smallest data value is 2.5 and the largest is 9.3. Therefore, the range is:

1. The steps that follow are also needed for finding the standard deviation. Start by writing the computational formula for the variance of a sample:

[tex]{s^2}= \frac{{\sum}{x^2} - \frac{({\sum}{x})^2}{n}}{n-1}[/tex]

2. Create a table of 2 columns and 14 rows. There will be a header row and a row for each data value. The header row should be labeled with x and x^2. Enter the data values in the x column, with each data value in its own row. In the second column, put the square of each of the data values, x^2.

8.7 75.69

3. Find the sum of all the values in the first column, [tex]{\sum}{x}[/tex].

[tex]\sum{x} = 86.4[/tex]

4. Square the answer from step 3, then divide that number by the size of the sample.

[tex]\frac{({\sum}{x})^2}{n} = \frac{7464.96}{13} = 574.22769230769[/tex]

5. Find the sum of all the values in the second column, [tex]{\sum}{x^2}[/tex].

[tex]{\sum}{x^2} = 625.76[/tex]

6. Subtract the answer in step 4 from the answer in step 5.

[tex]{\sum}{x^2} - \frac{({\sum}{x})^2}{n} = 625.76 - 574.22769230769 = 51.532307692308[/tex]

7. Divide the answer in step 6 by n - 1, one less than the size of the sample. This answer is the variance of the sample.

[tex]{s^2}= \frac{{\sum}{x^2} - \frac{({\sum}{x})^2}{n}}{n-1} = \frac{ 51.532307692308 }{12} = 4.294358974359[/tex]

To find the standard deviation, first write the computational formula for the standard deviation of the sample.

[tex]{s}= \sqrt{\frac{{\sum}{x^2} - \frac{({\sum}{x})^2}{n}}{n - 1}}[/tex]

Take the square root of the answer found in step 7 above. This number is the standard deviation of the sample. It is symbolized by [tex]s[/tex]. Here, we round the standard deviation to at most 4 decimal places.

[tex]{s} = \sqrt{4023.0714285714} = 63.4277[/tex]

Answer: n=-3 and n=3/2

Step-by-step explanation:

To solve the expression, we want to find the values of n. Since there are no common factors in 2, 3, -9, we directly multiply the "a" and "c" values.

2×(-9)=-18

This means, we want to find two numbers that multiply to -18 and adds to 3. This can also be known as the cross method.

We will find that 6 and -3 multiply to -18, and adds to 3.

In our box method, we want to find the common factors.

|2n²|6n|

|-3n|-9|

Note: Just pretend the lines line up and form a square box, with a term in each box.

After finding that is in common between the boxes, we get (n+3)(2n-3)=0

To solve, we set each factor equal to 0.

n+3=0

n=-3

2n-3=0

Answer:

y=|x|

Step-by-step explanation:

We know

general modulus function passes through origin as |0| is 0

And it's symmetric on both sides of y axis .

As it's not one -one function

Means

So the graph is y=|x|

Answer:

y = |x|

Step-by-step explanation:

The equation for the part of graph to the right of the y-axis is:  

y = x  where y ≥ 0

The equation for the part of graph to the left of the y-axis is:  

y = -x  where y ≥ 0

So we can see that both a positive and negative value of x gives the same positive value of y.

Therefore, we can create an equation for the graph by using the absolute value of x:

⇒ y = |x|

Absolute value means how far away a number is from zero.

"x" is x away from zero and "−x" is also x away from zero.

So the absolute value of x is x, and the absolute value of −x is also x.

The bars either side of the x shows that we want the absolute value of x.

In practice, think of "absolute value" as removing any negative sign in front of a number.

With y = x  →  when x = 1, y = 1  and  when x = -1, y = -1

With y = |x|  →  when x = 1, y = 1  and  when x = -1 we think of it as x = 1, so y = 1
