OC userin Physics·20 Dec 20175.19 .. CP A 750.0-kg boulder is raised from a quarry 125 m deep by a long uniform chain having a mass of 575 kg. This chain is of uniform strength, but at any point it can support a maximum tension no greater than 2.50 times its weight without breaking. (a) What is the maximum acceleration the boulder can have and still get out of the quarry, and (b) how long does it take to be lifted out at maximum acceleration if it started from rest?
OC userin Economics·19 Dec 2017Question 4. (15 marks) Suppose supply is given by q = 2 + p and demand by q = 10 – 2p. (a) Plot these curves with p on the vertical axis, showing the slopes and all horizontal and vertical intercepts. (b) Using the information from Question 3 calculate the equilibrium quantity and price. (C) Suppose the demand curve shifts such that q = 15 - 2p. Compute the new equilibrium price and quantity. Show this on your graph.
OC userin Accounting·20 Dec 2017EXERCISE 12-16 Identification of Relevant Costs [LO12-1] Bill has just returned from a duck hunting trip. He has brought home eight ducks. Bill's friend, John, disapproves of duck hunting, and to discourage Bill from further hunting, John has presented him with the following cost estimate per duck: $150 58 Camper and equipment: Cost, $12,000; usable for eight seasons; 10 hunting trips per season. ........... Travel expense (pickup truck): 100 miles at $0.31 per mile (gas, oil, and tires-$0.21 per mile; depreciation and insurance-$0.10 per mile) ....... Shotgun shells (two boxes) Boat: Cost, $2,320, usable for eight seasons; 10 hunting trips per season Hunting license Cost, $30 for the season; 10 hunting trips per season .......... Money lost playing poker: Loss, $24 (Bill plays poker every weekend) .................. Bottle of whiskey: Cost, $15 (used to ward off the cold) ........... Total cost .. Cost per duck ($272 = 8 ducks) .... $272 Required: 1. Assuming that the duck hunting trip Bill has just completed is typical, what costs are relevant to a decision as to whether Bill should go duck hunting again this season? 2. Suppose that Bill gets lucky on his next hunting trip and shoots 10 ducks in the amount of time it took him to shoot 8 ducks on his last trip. How much would it have cost him to shoot the last two ducks? Explain. 3. Which costs are relevant in a decision of whether Bill should give up hunting? Explain.
