Answer:
dP/dt = kP+r
Step-by-step explanation:
We know that in the absence of immigration and emigration, the growth of a country's population P(t) satisfies dP/dt = kP for some constant k > 0. Therefore, we have differential equation:
dP/dt = kP .
If individuals are allowed to immigrate into the country at a constant rate r > 0, we conclude that we have the differential equation
dP/dt = kP+r .
Answer:
48 is 60% of 80
Step-by-step explanation:
set it up as an equation
(100) 48 = 
× 80 (100)
4800 = 80x (divide both sides by 80)
x=60
meaning that 48 is 60% of 80
