Separable differential equations: Suppose a population P = P(t) grows in such a way that its rate of growth dPdtobeys the equation dPdt=P100-P

This is called a differential equation because it is an equation that involves a derivative. In the series of steps that follow, you will find a function P(t) that behaves according to this differential equation.

Use properties of logarithms to simplify the answer you found in the previous question.

Answer islnP100-P1100+C1

Step by step solution

01

Step 1. Given information

Differential equation isdPdt=P100-P

02

Step 2. Explanation

Consider the equation1100lnP-ln100-P+C1

Use the formula: lna-lnb=lnaband alnx=lnxa

1100lnP-ln100-P+C1=1100lnP100-P+C1=lnP100-P1100+C1
