Hi A population starts with 1, 000 individuals and triples every 80 years. (a) Give an exponential model for the situation. Q(t) = t being the time in years 3000 = 3 = e^80k ln3/80 = k = ..0137 Q(t) =

Each tripling happens in 80 years. One tripling is 80 years so will make the 1000 into 3000. If tbis way of thinking is used, then

.
x, number of years
y, population size

Population   P = 1000*3^(t/80), t is the time in years.         ANSWER

Solved.

        There is no need to convert it to ekt-form.

        Exponential function base 3 is no worse than ekt-form.

        Converting in this case is UNNECESSARY job.
