A population of bacteria in a petri dish is modeled by the function p(x) = 8^8x where x is the number of hours that have elapsed since the bacteria was introduced to the petri dish. When will there be fewer than 512 bacteria?
Enter your answer rounded to the nearest hundredth in the boxes.

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
