Answer:
Time it will take t = 23.1 (round to the nearest tenth)
Step-by-step explanation:
Given: A population of bacteria is growing exponentially;
According to the model;
......[1]; where P is the number of colonies and t be the time measured in hours.
After how many hours will 400 colonies be present.
Substitute value of P = 400 in [1];
Divide both sides by 100 we get;
Taking ln both sides we get;
Since;
then;
Divide both sides by 0.06 we get;
or
hours
Therefore, the time it will take is, t = 23.1 (round to the nearest tenth)
