Answer:

\frac{C}{2\pi } =r

Step-by-step explanation:

Recall to find the circumference of a circle the formula is C=\pi d or C=2\pi r. Since we need r, we will use the second formula for circumference.

We start by solving for r in the Circumference formula. using inverse operations. We divide both sides (as the inverse of multiply) by 2pi.

C=2\pi r\\\frac{C}{2\pi } =r.

Find the mean, median, and mode of 12, 9, 17, 15, 10
igor_vitrenko [27]

Answer:

Mean: 12.6

Median: 12

Mode: 9, 10, 12, 15, 17

Step-by-step explanation:

Mean: To find the mean you have to add up all your terms and divide your result by the number of terms you have. ((12+9+17+15+10) / 5)

Median: To find the median you have to organize your terms from least to greatest and then find your center term. (12)

Mode: Normally to find your mode would be to organize your terms from least to greatest and see which of your terms occurs the most. In this case all terms occur only once, making all your terms the mode.

mestny [16]

The length of the dilated line segment is 80 units.

<h3>What is dilation?</h3>

Dilation is the increase or decrease in the size of a figure or object.

The segment with endpoints (10,40) and (70,120) is dilated by a factor of 4/5 to get (8, 32) and (56, 96).

The distance between points (8, 32) and (56, 96) is:

Distance = \sqrt{(96-32)^2+(56-8)^2} =80\ units

The length of the dilated line segment is 80 units.
