Answer:
![\large\boxed{(x+5)^2+y^2=64}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7B%28x%2B5%29%5E2%2By%5E2%3D64%7D)
Step-by-step explanation:
The standard form of an equation of a circle:
![(x-h)^2+(y-k)^2=r^2](https://tex.z-dn.net/?f=%28x-h%29%5E2%2B%28y-k%29%5E2%3Dr%5E2)
(h, k) - center
r - radius
We have the center (-5, 0) and the radius r = 8. Substitute:
![(x-(-5))^2+(y-0)^2=8^2\\\\(x+5)^2+y^2=64](https://tex.z-dn.net/?f=%28x-%28-5%29%29%5E2%2B%28y-0%29%5E2%3D8%5E2%5C%5C%5C%5C%28x%2B5%29%5E2%2By%5E2%3D64)
Answer:
18 centimeters
Step-by-step explanation:
Divide the circumference by π, or 3.14 for an estimation. The result is the circle's diameter.
Divide the diameter by 2.
There you go, you found the circle's radius
Answer: It's (3,-2)
Step-by-step explanation:
Answer:
x = 2
Step-by-step explanation:
note that 4096 =
, then
= ![8^{4}](https://tex.z-dn.net/?f=8%5E%7B4%7D)
Since bases on both sides are equal, both 8 , then equate the exponents
2x = 4 ( divide both sides by 2 )
x = 2
