While growing bacteria in a laboratory Petri dish, a scientist notices the number of bacteria over time. The observations are shown in the table. Number of bacteria
Number of minutes
from initial state
0 4
5 128
10 4096
15 131072

What function can be used to describe the number (n) of bacteria after 2 minutes?

The function that can be used to describe the number (n) of bacteria after 2 minutes is;

Step-by-step explanation:

The data in the table are presented as follows;

Number of bacteria; 4, 128, 4,096, 131,072

Number of minutes from initial state; 0, 5, 10, 15

The general equation for population growth is presented as follows;

Where;

P = The population after 't' minutes

P₀ = The initial population

r = The population growth rate

t = The time taken for the growth in population numbers

At t =  minutes. we have;

∴ P₀ = 4

At t = 5, we have;

∴ r × 5 = ㏑(32)

r = ln(32)/5 ≈ 0.693

The number (n) of bacteria after 2 minutes is therefore;

a - base

b - exponent

so,
