Enter the expression n0e−λt, where n0 is n-naught (an n with a subscript zero) and λ is the lowercase greek letter lambda.

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

(a) the volume of the cone is 20/3 in3

hence, option a is correct.

true !
