Answer:
r = 5
Step-by-step explanation:
Compare this equation to the standard form
(x - h)^2 + (y - k)^2 = r^2
Through this comparison we see that h = 0, k = 8 and r = 5.
D
Area of the base
Answer: c = -5, -8
c^2 +13c+40=0
(c+5)(c+8)=40
c = -5, -8
90+35+x=180
×=180-90+35
×=180-125
×=55
After 7 years, the value would be $9,046.
After 13 years, the value would be $3,660
