Hello!

To find the length of a circle, you will need the following formula:
 $\boxed{\boxed{C = 2* \pi *r }}$ 

Having the following data: $\pi$ approximate is $3.14$ and also the value of the radius (r) of the circumference, known the value of the radius (r), the length of the circumference is given by twice the product of the radius by $\pi$ .

A circle is 360° all the way around; therefore, if you divide an arc’s degree measure by 360°, you find the fraction of the circle’s circumference that the arc makes up. Then, if you multiply the length all the way around the circle (the circle’s circumference) by that fraction, you get the length along the arc.

Higher Order Thinking On Friday,

Answer:

The Total number of peoples went to street fair including all three days is 785 peoples .

Step-by-step explanation:

Given as :

The number of people went to fair on Friday = F = 215 peoples

The number of people went to fair on Saturday = Sa = 163 more people than on Friday

So, The number of people went to fair on Saturday = The number of people went to fair on Friday + 163 peoples

∴, The number of people went to fair on Saturday = 215 + 163 = 378 peoples

And

The number of people went to fair on Sunday = Su = 192 peoples

So , The Total number of peoples went to fair = The number of people went to fair on Friday + The number of people went to fair on Saturday + The number of people went to fair on Sunday

So, The Total number of peoples went to fair = 215 peoples + 378 peoples + 192 peoples

∴ The Total number of peoples went to fair = 785 peoples

Hence , The Total number of peoples went to street fair including all three days is 785 peoples . Answer

Let's complete the square

f(x) = x^2 + 6x + 8

y = x^2 + 6x + 8

y-8 = x^2 + 6x

y-8+9 = x^2+6x+9 .... see note below

y+1 = (x+3)^2

y = (x+3)^2-1

note: I added 9 to both sides due to taking half of the 6, and then squaring that result.

We'll restrict x such that $x \ge -3$ to ensure that this function is one-to-one.

Now we need to swap x and y, and solve for y to get the inverse

y = (x+3)^2 - 1

x = (y+3)^2 - 1

x+1 = (y+3)^2

(y+3)^2 = x+1

y+3 = sqrt(x+1)

y = sqrt(x+1)-3

g(x) = sqrt(x+1)-3 is the inverse

The graph is shown below. The original function is in red. The inverse is in blue. The inverse is the result of reflecting the red curve over the dashed line y = x. So this explains why x and y swap places. Consequently, the domain and range also swap as well.

Volunteers for a political campaign gave out 21/38 of their fliers. They gave out the remaining 612 fliers in another neighborho

wel

Answer:

The total number of fliers the volunteers gave out is 1,368: 756 in the first neighborhood and 612 in the second.

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Amount of fliers the volunteers gave for a political campaign = 21/38

Remaining 612 were given out in another neighborhood

2. What is the total number of fliers they gave out?

x = Total of fliers

21x/38 = Fliers given out in the first neighborhood

612 = Fliers given out in the second neighborhood

Let's solve for x, this way:

x - 21x/38 = 612

38x - 21x = 612 * 38 (38 is the Lowest Common Denominator)

17x = 23,256

x = 23,256/17

x = 1,368

The total number of fliers the volunteers gave out is 1,368: 756 in the first neighborhood and 612 in the second.

Answer:

Yes it is a proportional relationship

Step-by-step explanation:

You can see a clear pattern, every time time goes up by a minute earning go up by 6. There is no random numbers without pattern. So it’s proportional.
