G=2,0 I have notes
If u want I can explain
The equation of a circle exists:
, where (h, k) be the center.
The center of the circle exists at (16, 30).
<h3>What is the equation of a circle?</h3>
Let, the equation of a circle exists:
, where (h, k) be the center.
We rewrite the equation and set them equal :
![$(x-h)^2 + (y-k)^2 - r^2 = x^2+y^2- 32x - 60y +1122=0](https://tex.z-dn.net/?f=%24%28x-h%29%5E2%20%2B%20%28y-k%29%5E2%20-%20r%5E2%20%3D%20x%5E2%2By%5E2-%2032x%20-%2060y%20%2B1122%3D0)
![$x^2 - 2hx + h^2 + y^2 - 2ky + k^2 - r^2 = x^2 + y^2 - 32x - 60y +1122 = 0](https://tex.z-dn.net/?f=%24x%5E2%20-%202hx%20%2B%20h%5E2%20%2B%20y%5E2%20-%202ky%20%2B%20k%5E2%20-%20r%5E2%20%3D%20x%5E2%20%2B%20y%5E2%20-%2032x%20-%2060y%20%2B1122%20%3D%200)
We solve for each coefficient meaning if the term on the LHS contains an x then its coefficient exists exactly as the one on the RHS containing the x or y.
-2hx = -32x
h = -32/-2
⇒ h = 16.
-2ky = -60y
k = -60/-2
⇒ k = 30.
The center of the circle exists at (16, 30).

If the order of the numbers in the question are the order Darrin put theem in then no, his work is not correct. this is because 7.25 is not greater than 7.52. the real order should be 7.52,7.25, 5.72, 5.27
Answer:
30+18 x
