The circumference of the circle is given by C = 2 π r

If the radius of the circle is doubled, then new radius will be r' = 2r.

And new circumference will be C' = 2·π·(2r) = 2·(2 π r) = 2·C

It is clearly visible that new circumference is twice the original circumference i.e. C' = 4 π r

The distance y (in centimeters) a spring is compressed by a force x (in kilograms) is given by

kirza4 [7]

Answer:

(x, y) = {(20, 1.3), (40, 2.6), (60, 3.9), (80, 5.2), (100, 6.5)}

Graph C represents the table of values

Step-by-step explanation:

To complete the table, substitute each value of x into the equation, $y = 0.065x$ , to find each corresponding y-value.

Thus:

✔️When x = 20:

$y = 0.065x$

$y = 0.065(20)$

$y = 1.3$

✔️When x = 40:

$y = 0.065x$

$y = 0.065(40)$

$y = 2.6$

✔️When x = 60:

$y = 0.065x$

$y = 0.065(60)$

$y = 3.9$

✔️When x = 80:

$y = 0.065x$

$y = 0.065(80)$

$y = 5.2$

✔️When x = 100:

$y = 0.065x$

$y = 0.065(100)$

$y = 6.5$

✔️<em>The graph of that represents this table of values is graph C. See attachment.</em>

The rabbit population in a certain area is 500% of last year's population. There are 700 rabbits this year. How many were the

Ksenya-84 [330]

For this case we have the following data:

700 rabbits that represent 500% of the population of last year. So, to obtain the rabbit population of last year, we developed a rule of three:

700 -----------> 500%

x ---------------> 100%

Where x represents the rabbit population of last year.

Clearing x we have:

$x = \frac{ 100 * 700}{500}$

$x = 140$ rabbits

In this way, last year there was a population of 140 rabbits.

Answer:

140 rabbits
