Answer:
Center (-13,11) , radius 3
Step-by-step explanation:
The given circle has equation
We compare this to the general equation.
where (-a,-b) is the center.
This implies that;
2a=26
2b=-22
b=-11
The center is therefore (-13,11)
The radius is given by
The radius is 3
42,600 - 25,800 = 16800. That is the increase in 15 years.
You then calculate the increase as a percentage of the original population; 25,800.
16,800 / 25,800 * 100 = 65.11%
