Answer:
Atotal = 697.5 ft^2
Step-by-step explanation:
See picture.
Make three separate rectangles with Area 1, Area 2 and Area 3.
Total area (Atotal) of the pool cover, is the addition of all seperate areas.
Atotal = Area 1 + Area 2 + Area 3
See picture and use those measurements, (all in feet)v
Atotal = (10 * 7.5) + (8 * 7.5) + (45 * 12.5)
Atotal = ( 75 ) + ( 60 ) + ( 562,5 )
Atotal = 697.5 ft^2
First we can simplify a bit by dividing by 2500:
3 = 8 * (0.85)^x => 0.85^x = 3/8
next, we can take the log() on both sides, and use the fact that log(a^b)=b*log(a)
log(3/8) = log(0.85^x) => log(3/8) / log(0.85) = x
If you calculate this, you find x ≈ 6.03
