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

Step-by-step explanation:

Continuous exponential growth model:

Where α is the growth rate parameter.

So if t is the starting point and t+t1 is the point that population is doubled:

So:

And as a result, t1, the time needed for the population to double at ANY given point is equal to:

b. hoped i'm right lol

step-by-step explanation:

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
