In Exercises 23 to 40, solve each equation.
L21 - 2 To solve a related rates problem: 1. Identify the desired rate of change; assign variables to all related quantities. Determine what rate(s) are given at a particular instant in time and express using your variables. Draw a sketch if possible. 2. Write an equation (mathematical model)r nighe variables involved from step 1. 3. Diļ¬erentiate the equation implicitly with respect to time. 4. Substitute known values and solve for the desired rate of change.
