Find the particular solution that satisfies the initial condition. Differential Equation Initial Condition dr r 55 2 e 0 = 0 d5 r( ) First, rewrite the equation as 23 = ere d5 Now, separate variables to obtain (2e_r)dr = (e )ds. Write and solve the differential equation that models the verbal statement. (Use k for the constant of proportionality.) The rate of change of y is proportional to y. When x = 0, y = 22, and when x = 5, y = 99. What is the value of y when x = 10? Evaluate the solution at the specified value of the independent variable. y =
