Question

The change to a villages population over time can be represented using an exponential decay function.

P(t) = P₀e^rt(t ≥ 0)

P(t) represents the village population at time (t), measured in years. Initially at time t=0, there are 12,000 people in the village. After 4 years, only 5,000 people remain.

A. Show the value of P₀ is 12,000 and hence, state the equation for P(t)

B. Show that the value of the constant r is −0.219 to three significant figures.

C.
