Question 2 The figure given below is a storage tank that contains a liquid at depth y where y 0 meters when the tank is half full. Liquid is withdrawn at a constant flow rate Q to meet demands. The contents are resupplied at a sinusoidal rate 3Q sin(t). The equation "Change increases decreases" can be written for this system as dt (Change in volume) (inflow) (outflow) or, since the surface area A is constant, Use Euler's method to solve for the depth y from t 0 to 10 days with a step size of 0.5 day. The parameter values are A 1250 m2 and Q 450 m3/day. Assume that the initial condition is y o meters. (Round the final answers to five decimal places.) Present your answer in the form of a table of calculated values and a plot. Show details of your work for the first three calculations. MATLAB must be used to calculate the values for the table and when creating the plot. Question 3 Convert the following base 8 numbers to base 10: a. (66243)810 (Round the final answer to the nearest whole number) b. (3.26)8 10 (Round the final answer to five decimal places) Perform all calculations manually and show your work. Question 4 If Ixl
