Step-by-step explanation:
The population at various days is as follows since population triples every 3 days
<u>Day</u> <u>Population</u>
0 10
3 30
6 90
9 270
.... ......
This can be modeled by the general equation
where
is the population after t days
is the population at start (10)
is the rate at which population changes ie 3
is the number days from start
is the number of days at which the population triples(here k =3 days)
We can check this by plugging in values for each of the variables
At day 0, population = 10(3)⁰ = 10. 1 = 10
Similarly populations for days 3, 6, 9 are:
