Answer:
division
Step-by-step explanation:
With the division sign you divide you have 4 or 5 you divide 4 over 5
Given:
The diameter of a circle = 20 feet
To find:
The exact circumference of the circle.
Solution:
We know that the radius is half of the diameter of the circle.
The diameter of a circle is 20 feet. So, the radius of the circle is 10 feet.
The circumference of the circle is:
![C=2\pi r](https://tex.z-dn.net/?f=C%3D2%5Cpi%20r)
Where, r is the radius.
Substituting
, we get
![C=2(3.14)(10)](https://tex.z-dn.net/?f=C%3D2%283.14%29%2810%29)
![C=(6.28)(10)](https://tex.z-dn.net/?f=C%3D%286.28%29%2810%29)
![C=62.8](https://tex.z-dn.net/?f=C%3D62.8)
Therefore, the exact circumference of the circle is 62.8 feet.
Note: All options are incorrect.
Answer:
y = 2x - 8
Step-by-step explanation:
<u><em>To solve for slope, you need to use the formula:</em></u>
m = ![\frac{y_{2}-y_{1} }{x_{2}-x_{1} }](https://tex.z-dn.net/?f=%5Cfrac%7By_%7B2%7D-y_%7B1%7D%20%20%7D%7Bx_%7B2%7D-x_%7B1%7D%20%20%7D)
<u><em>Then, plug in the numbers accordingly:</em></u>
m = ![\frac{4 + 2 = 6}{6 - 3 = 3}](https://tex.z-dn.net/?f=%5Cfrac%7B4%20%2B%202%20%3D%206%7D%7B6%20-%203%20%3D%203%7D)
m = ![\frac{6}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B3%7D)
<u><em>Simplify:</em></u>
m = 2
<u><em>Then to find the y-intercept, you take one of the coordinates (doesn't matter which one) and plug it into the equation:</em></u>
Coordinate : (3, -2)
-2 = 2(3) + b
-2 = 6 + b
<u><em>Subtract 6 from both sides:</em></u>
-2 = 6 + b
-6 -6
_________
-8 = b
<u><em>Put it all together:</em></u>
y = 2x - 8
It’s y=1/3x-2 I hope it’s help u
