The number of bacteria in a certain population increases according to a continuous exponential growth model, with a growth rate parameter of 2.4% per hour. How many hours does it take for the size of the sample to double?

It would take approximately 289 hours for the population to double

Explanation:

Recall the expression for the continuous exponential growth of a population:

where N(t) measures the number of individuals, No is the original population, "k" is the percent rate of growth, and "t" is the time elapsed.

In our case, we don't know No (original population, but know that we want it to double in a certain elapsed "t". We also have in mind that the percent rate "k" would be expressed in mathematical form as: 0.0024 (mathematical form of the given percent growth rate).

So we need to solve for "t" in the following equation:

Which can be rounded to about 289 hours

f=ma a/f/m a= 480/60 a = 8m/s/s that is quick wow

a lot of it means it can be "burned" for energy and sold at one price. if it is scarce, the price will go up
