Problem 1: Trees are known as rain time machines, which is whence the ancient Canadian proverb comes: "Stand under a tree to find out what the weather was 10 minutes ago, eh." Below is an o.d.e. for a tree, where y(t) denotes the amount of rain falling out of the tree, u(t) denotes the amount of rain falling into the tree, k is some constant, and time is measured in minutes. 10? + y = ku, a) Determine a value for k¹² Explain your reasoning. b) Write the o.d.e. for time measured in seconds. c) Use MATLAB's step function to simulate the given system with time in minutes from t = 0 to t = 30 minutes. d) Use MATLAB's lsim function to simulate the unit step response for the system you made with time in seconds from t = 0 to t = 30 minutes. e) Plot both results in the same plot with time in minutes. Make one of the curves dashed to make sure we can see them both. Remember axis labels and legend.

The table below has a production schedule for Wendy's Washers, a mobile car cleaning service that receives an average price of $25 per car. Assume employees have identical skills and labor is the only variable input (customers provide their own cleaning products and water). Assume Wendy's operates in perfectly competitive input and output markets, and has fixed costs of $10 per day. L is the number of workers and Q is the number of cars washed per day. Labor = L Wendy's Output = Q Wendy's MPL Wendy's MRPL 0 0 1 4 2 9 3 15 4 20 5 24 6 26 Fill in the blanks below assuming Wendy is a profit-maximizing employer who follows the profit-maximizing hiring rule and does not discriminate when hiring labor. 1.
