"<span>How many times more did Carol eat compared to Dima?" is quite different from the previous question, in which you asked "how much more did Carol eat than Dima?" I think they ate 10/25 and 9 /25 of the cake, respectively.
10/25 is greater than 9/25, obviously. We need to calculate "how many times greater is 10/25 than 9/25? So we divide 9/25 INTO 10/25. This comes out to 10/9, or 1.11 times as much. Carol eats 11% more cake than Dima. Hope she doesn't gain too much extra weight. ;)</span>
We have the following equation:
x2 + y2 + 6y - 72 = 0
Rewriting we have:
x2 + y2 + 6y = 72
Complete squares we have:
x2 + y2 + 6y + (6/2) ^ 2 = 72 + (6/2) ^ 2
x2 + y2 + 6y + (3) ^ 2 = 72 + (3) ^ 2
x2 + y2 + 6y + 9 = 72 + 9
x2 + (y + 3) 2 = 81
So, the center is:
(0, -3)
The radio is:
r = 9
Answer:
(0, -3)
r = 9
