The number of bacteria in a certain culture doubles every hour. If there were 30 bacteria present in the culture originally, how many bacteria will be present at the end of 2nd hour, 4th hour and nth hour?

The number of bacteria in a certain culture doubles every hour. If there were 50 bacteria present in the culture originally, how many bacteria would be present at the end of (i) 2nd hour, (ii) 5th hour and (iii) nth hour ?

The rate of increase in the number of bacteria in a certain bacteria culture is proportional to the number present. Given the number triples in 5 hrs., find how many bacteria will be present after 10 hours. Also find the time necessary for the number of bacteria to be 10 times the number of initial present. [Given log_e3=1. 0986 , e^(2. 1972)=9 ]

If a bacterium cell divides it every 20 minutes, how many bacteria will be formed in two hours?

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 of increase in the number of bacteria in a certain culture is propotional to the number present at that time. After 2 hours there are 600 bacteria and after 8 hours the count is 75000, then the population will be 200000 after

The rate of increases of bacteria in a certain culture is proportional to the number present. If it doubles in 5 hr.then in 25 hr.its number would be

The rate of increase in the number of bacteriad in a certain bacteria culture is propotional to the number present at that time. After 2 hours there are 600 becteria and after 8 hours the count is 75000, then the initial population is
