Ответ:
Using an exponential function, it is found that the hourly growth rate of the bacteria culture is of 14.9%.
------------------------
An exponential function has the following format:
In which:
A(0) is the initial amount.r is the hourly growth rate.------------------------
Since it doubles every 5 hours, it means that:
And we use this to find r.
------------------------
0.149*100% = 14.9%.
The hourly growth rate of the bacteria culture is of 14.9%.
