Answer:
The bacterial culture loses
of its size every 7 seconds.
Step-by-step explanation:
The relationship between the elapsed time t, in seconds, and the number of bacteria, N(t), in the petri dish is modeled by the function:

Since the growth factor is less than 1, it is a decay equation.

Observe that the time t is divided by 7.
This is the period.
We can therefore say that the bacterial culture loses
of its size every 7 seconds.
