The population of a bacteria culture doubles in number every 12 minutes. The ratio of the number of bacteria at the end of 1 hour to the number of bacteria at the beginning of that hour is

The rate of increase in the numbers of bacteria culture is proportional to the number present.If initially there were 1000 bacteria and the number doubles in 1 hour,find the number of bacteria after a time of 2 1/2 hours.

A population of bacteria doubles every 2 hours . What is the percent increase after 4 hours ?

A population of bacteria doubles every 2 hours. What is the percent increase after 4 hours ?

The rate of increase in the number of bacteria in a certain bacteria culture is proportional to the number present. If in 5 hrs the number triples, then in 10 hrs, the number of bacteria present is

The rate of increase of the bacteria in a culture is proportional to the number of bacteria present and it is found that the number doubles in 6hours.Prove that the bacteria becomes xx at the end of 18 hours.

The rate o growth of bacteria is proportional to the number present . If intially, there were 1000 bacteria and the number doubles in 1 hours. Find the number of bacteria after 2""1/2 hours . [ take sqrt 2 = 1.414]

In a certain culture the rate of increment of bacterial at any instant is proportional to the cube root of the number of bacteria present at that instant. IF the number of bacteria becomes 8 times in 3 hours, in how much time that number becomes 64 times?
