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 = 0.087 (4.2 I) a) Select the correct descriptions about the differential equation. dW C] The differential equation is second order C] The differential equation is separable [3 According to the differential equation, the rate of change of I with respect to W is proportional to soil moisture C] The differential equation is linear b) If I has an initial value of 2 when W = O, solve the initial value problem. mm = c) What happens to I as W becomes larger and larger? Answer: As W becomes larger and larger, I approaches
