a culture of bacteria obeys the law of uninhibited growth. if 140,000 bacteria are present initially
and there are 609,000 after 6 hours. how long will it take for the population to reach 1000000?:
Solution
law of uninhibited growth.
at t=6 hrs bacteria=609000
so equation becomes
n=140000e^(kt)
t=6 n=609000
so k=1/6*ln(609000/140000)=0.245029
so our equation becomes
n=140000e^(0.245029*t )
when n=1000000 then t=??
t=1/0.245029*ln(1000000/140000)=8.0239 hrs
