3. Some populations (such as algae and bacteria) produce waste products, which in high
concentrations are toxic to the population itself. A mathematical model for a population
x(1) and a toxic waste product y(t) is
dx
(а - В — Ку)х,
dt
(5)
dy
= yx – ôy,
dt
where a, B, y, 8 and K are positive constants.
