A certain index I is a measure of soil moisture. An article described the rate of change of I with respect to W, the amount of water in the following equation. Use the equation to answer the questions. di 0.082(4.3 - I) a) Select the correct descriptions about the differential equation. dw The differential equation is separable The differential equation is linear According to the differential equation, the rate of change of I with respect to W is proportional to soil moisture O The differential equation is second order b) If I has an initial value of 2 when W = 0, solve the initial value problem. I(W) = c) What happens to I as W becomes larger and larger? Answer: As W becomes larger and larger, I approaches
