Answer:
20) 8 years
21) Tori could paint the room alone for 3 hours, Sydney could paint the room alone for 5 hours.
Step-by-step explanation:
A = P ( 1 + r/n ) ^ nt.
8000 = 5000 ( 1 + 6%/4) ^ 4t
8000 = 5000 ( 1 + 0.06/4) ^4t
8000 = 5000 ( 1 + 0.015 ) ^ 4t
8000 = 5000 ( 1.015 ) ^ 4t
8000 / 5000 = ( 4.06 / 4 ) ^ 4t
8/5 = ( 203/200 ) ^ 4t
b = aᶜ ⇔ logₐb = c

Answer:
Coordinates of the midpoint are ( 9/2 , -6 )
we have M is durectly porpotional to r^2
so M=(k)r^2
and when r=2, m=14
so 14=(k)(2)^2
k=14/4 =7/2
so when r=12
m= (7/2)(12)^2 =(7/2)(144) = 504
