Step-by-step explanation:
Answer:
The radius is: ![2\sqrt{3}](https://tex.z-dn.net/?f=2%5Csqrt%7B3%7D)
Step-by-step explanation:
The equation of a circle in center-radius form is:
![(x - h)^2 + (y - k)^2 = r^2](https://tex.z-dn.net/?f=%28x%20-%20h%29%5E2%20%2B%20%28y%20-%20k%29%5E2%20%3D%20r%5E2)
Where the center is at the point (h, k) and the radius is "r".
So, given the equation of the circle:
![x^2+y^2=12](https://tex.z-dn.net/?f=x%5E2%2By%5E2%3D12)
You can identify that:
![r^2=12](https://tex.z-dn.net/?f=r%5E2%3D12)
Then, solving for "r", you get that the radius of this circle is:
![r=\sqrt{12}\\\\r=2\sqrt{3}](https://tex.z-dn.net/?f=r%3D%5Csqrt%7B12%7D%5C%5C%5C%5Cr%3D2%5Csqrt%7B3%7D)
Answer: 5;6
Step-by-step explanation:
10 divided by 2 is 5
12 divided by 2 is 6 and plus I got this answer correct
F(-1) = 12 - 5(-1)
f(-1) = 12 + 5
Solution: f(-1) = 17
Your question is very confusing but x=8 so just plug in 8 where you see X
