MatLab: Let z = magic(5). a. Perform the following operations on z in the given order: i. Divide column 2 by 3. ii. Add the elements of the third row to the elements in the fifth row (the third row remains unchanged). iii. Multiply the elements of the first column by the corresponding elements of the fourth column and place the result in the first column. iv. Set the diagonal elements to 2.

Putting it All Together. Using the 3-Step Process from Example #3, solve the following: 1. Suppose the changes in water level in Example #3 follow the differential equation below during the 12 months following the initial study period. a. Based on the differential equation, what will happen to the water level during the second year? Explain using words and a graph. b. Find an antiderivative for dw2/dt and solve for C. Record the function, w2(t), that precisely describes the water level during the second year. c. According to the model, what will be the water level at the end of the second year? At the halfway point? d. Assuming the initial study period began on Jan 1, 2011, when do the models suggest the water level will fall below 5 inches? Round to the nearest month. 2. Find an approximate formula for the function y = f(x) satisfying the differential equation below and passing through the point (2, -20). Include both an equation and a graph over the interval [0, 3] to illustrate your solution.
