Population decay where rate of decay is proportional to the population present
Step-by-step explanation:
Given that
Here N (t) represents the population or amount of bacteria present at time t.
N0 represents the initial population or N(0)
Since e has negative exponent, there is population decay and not expansion.
l, the coefficient of t in the exponent of e is the factor which represents the rate of decay
Whenever decay is proportional to the population present at that time, we get this equation.
N'=-lN
Separate the variables and integrate to get
