Which one of the following is a true statement about a circle inscribed in a regular polygon?

1 answer:

7 0

Given that a circle is inscribed in a regular polygon, it is true that the sides of the polygons are tangents of the circle. The area of the circle is always less than the area of the polygon. When the polygon is inscribed in the circle, then the sides of the polygon are chords of the circle and t<span>he vertices of the polygon are on the circumference of the circle. Answer is D. </span>

Help! If a = 57 in, b = 23 in, c = 72 in, and d = 26 in, what is the perimeter?

Oliga [24]

Answer: The correct answer is B. 350in

Step-by-step explanation: because there is one c, two a, four b, two d, and you have to add 20 for the extra space that didn’t have a measurement. So 72+57+57+23+23+23+23+26+26+20=350

Eddi Din [679]

The surveyor selects the twentieth student who enters the building. The student do not enter the building to be surveyed but for other reasons and the researcher take advantage of that and selects them. This is a form of continence sampling.
The researcher selects every twentieth student and not any other. Therefore, the sampling is systematic in nature.
Finally, students selected to participate in the survey are free to choose if to participate in he survey or not. Therefore, it is voluntary kind of sampling.

Therefore, the applicable sampling methods are convenience, systematic, and voluntary.

Since, the fundraiser only have three prices for books($2, $5 and $10), the number of $5 book that was sold is 12.

<h3>How to form equation and solve ?</h3>

The fundraiser only have 3 prices for books which are $2, $5 and $10.

There were 6 more $5 books sold than $10 books sold.

Let

x = number of $10 book sold

Therefore,

number of $5 books sold = x + 6

There are 8 more $2 book sold than $10 book sold. Therefore,

number of $2 books sold = x + 8

A total of $250 was raised.

Therefore, the total amount sold forms the following equation:

10x + 5(x + 6) + 2(x + 8) = 250

10x + 5x + 30 + 2x + 16 = 250

17x = 250 - 30 - 16

17x = 204

x = 204 / 17

x = 12

What is the x-intercept of a line that passes through the point (3,4) and has a slope of 2?

Blababa [14]

Answer:

(1,0)

Step-by-step explanation:

Hi there!

We want to find the x intercept of the line that passes through the point (3,4) and has a slope of 2

First, let's find the line

We are given both a slope, and a point. We can write the equation of the line in point-slope form, which is $y-y_1=m(x-x_1)$ , where m is the slope and $(x_1, y_1)$ is a point

We do have everything needed to write the equation, let's just label everything to avoid confusion:

m=2

$x_1=3$

$y_1$ =4

Now substitute those values as the variables that they represent into the equation:

$y-y_1=m(x-x_1)$

y-4=2(x-3)

Now we have the equation in slope-point form

The x intercept of the line is the value in which the line passes through the x axis. The value of y at this point is 0

So we can substitute y as 0 in the equation to find out the value of x:

y-4=2(x-3)

0-4=2(x-3)

Multiply

0-4=2x-6

Add 6 to both sides

0+2=2x

Simplify the left

2=2x

Divide both sides by 2

1=x

So the value of the x intercept is 1, also written as the point (1,0)

Hope this helps!
