Answer:
a) k=2.08 1/hour
b) The exponential growth model can be written as:
c) 977,435,644 cells
d) 2.033 billions cells per hour.
e) 2.81 hours.
Step-by-step explanation:
We have a model of exponential growth.
We know that the population duplicates every 20 minutes (t=0.33).
The initial population is P(t=0)=58.
The exponential growth model can be written as:
For t=0, we have:
If we use the duplication time, we have:
Then, we have the model as:
The relative growth rate (RGR) is defined, if P is the population and t the time, as:
In this case, the RGR is k=2.08 1/h.
After 8 hours, we will have:
The rate of growth can be calculated as dP/dt and is:
For t=8, the rate of growth is:
(2.033 billions cells per hour).
We can calculate when the population will reach 20,000 cells as:
