22000=15000(1+.089/4)^4t
22/15=(1.02225)^4t
log(22/15)=4tlog1.02225
(log(22/15)/4log1.02225)=t
(.16633/.038228)=t
t=4.35 years or 4 years and approximately 4 months

a. The center of the circle will be the coordinate point of the marked point inside the circle.

center: (3,-5)

The radius is the distance between the center and any point on the circle.

radius: 4 units

b. standard form for circles: (x-h)²+(y-k)²=r² where (h,k) is the center

standard form: (x-3)²+(y+5)²=16

c. Simplify equation in standard form to get general form.

(x-3)²+(y+5)²=16

x²-6x+9+y²+10y+25=16

general form: x²+y²-6x+10y+18=0
