A culture of bacteria has an initial population of 420 bacteria and doubles every 5 hours. Using the formula Pę = P,. 28, where Pr is the population after t hours, Po

is the initial population, t is the time in hours and d is the doubling time, what is the

population of bacteria in the culture after 9 hours, to the nearest whole number?

hi,

6x times 4 is 24x and 5 times 4 is 20, so the answer is 24x+20.

hope this and for a little humor i am groot.

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

i would say b) is your answer

sorry if im wrong

step-by-step explanation:

it would take 5 hours i think idk i'm not that good at math.can you me with my questions i need asap.
