Consider a small landscaping company run by Mr. Viemeister. He is considering increasing his firm's capacity. If he adds one more worker, the firm's total monthly revenue will increase from $52,000 to $60,000. If he adds one more tractor, monthly revenue will increase from $52,000 to $64,000. Each additional worker costs $4,000 per month, while an additional tractor would also cost $4,000 per month. Instructions: Enter your answers as a whole number. a. What is the marginal revenue product of labor? The marginal revenue product of capital? b. What is the ratio of the marginal revenue product of labor to the price of labor ($MRP_L \div P_L$)? What is the ratio of the marginal revenue product of capital to the price of capital ($MRP_C \div P_C$)? c. Is the firm using the least-costly combination of inputs? d. Does adding an additional worker or adding an additional tractor yield a larger increase in total revenue for each dollar spent?

Question 5 of 7 1 Points. Point(s) deducted for incorrect answer: 0.5 Losses in a lossy transmission line only changes the shape and not the magnitude of the voltage pulse travelling in the line True False Rationale: Question 6 of 7 15 Points A communication cable runs from the basement to the 11th floor of a multistory building. The cable is 200 m long. The cable inductance and capacitance are 5 $\mu$H/m and 10 pF/m respectively. A 10 V square voltage pulse arrives at the source-end of the cable. Assume that the cable is lossless as well as no voltage initial conditions in the cable. Calculate the following; give answers rounded up to 2-decimal places. (i) The cable characteristic impedance is $Z_0 =$ (ii) The speed of propagation $V_p$ in the cable is = (iii) If the cable load-end is open circuit, the time difference in $\mu$s between the initial voltage pulse and arrival of the first reflected voltage pulse at the cable source-end is $\Delta t =$ (iv) If the cable load-end is short circuit, the voltage magnitude across the cable-end terminals is $V =$ (v) If the cable and its load are impedance matched, the magnitude of the current impulse through the load impedance is $I = $
