Assume that in the absence of immigration and emigration, the growth of a country's population P(t) satisfies dP/dt = kP for som

Morgarella [4.7K]

Answer:

A) Differential equation for population growth in case of individual immigration is:

$\frac{dP}{dt}=kP+r$

B) Differential equation for population growth in case of individual emigration is:

$\frac{dP}{dt}=kP-r$

Step-by-step explanation:

Population growth rate in the absence of immigration and emigration is given as:

$\frac{dP}{dt}=kP--(1)$

A) When individuals are allowed to immigrate:

Let r be the constant rate of individual immigration given that r >0.

Differential equation for population growth in this case is:

$\frac{dP}{dt}=kP+r$

B) In case of individual emigration:

Let r be the constant rate of individual emigration given that r >0.

Differential equation for population growth in this case is:

$\frac{dP}{dt}=kP-r$

Solve the proportion by using cross products.

algol13

Answer:

Step-by-step explanation:

Multiply 8 and <em>n </em>to get 8n

Multiply 3 and 192 to get 576

Write them equal to each other $8n=576$

To isolate the variable divide by 8 on both sides

$\frac{567}{8} =72$
