A bacteria population is growing exponentially with a growth factor of 18 each hour. By what growth factor does the population change each half hour?

The bacteria population has an exponential growth with a factor of 18 per hour. The growth factor has to be determined for the population change each half hour.

Step 2

To find the growth factor for every half an hour as follows,

For an exponential function,$$\text{Growth factor of one hour} = (\text{Growth factor of half an hour})^{2}$$ K Assuming growth factor of half an hour as x, $$18=x^{2} x=\sqrt{18} x=3\sqrt{2}$$

Hence the growth factor is $$x=3\sqrt{2}$$
