3323.5 because if you times the number left by the 15 percent this is the answer.
Answer:
The initial number of bacteria in the culture was 1949
Step-by-step explanation:
The relative growth rate for a certain type of bacteria population is 78% per hour.
As we know the growth of bacteria is exponential function.

where,
P is population of bacteria after n hours.
P₀ is initial population.
r is rate of growth per hour
n is number of hours
A small culture has formed and in just 5 hours the count shows to be 34,820 bacteria in the culture.
P = 34820 , n = 5 , r = 0.78



Hence, The initial number of bacteria in the culture was 1949
Answer:
WHAT?
Step-by-step explanation:
Answer: x - 12
<u>Step-by-step explanation:</u>
Area = Length * width
x² - 144 = (x + 12) * width
<u>÷(x + 12)</u> <u>÷(x + 12) </u>
= width
= width
x - 12 = width
