You are the building manager for a cylindrical skyscraper with a slanted roof. You must contract a window cleaner fwho works for $35 an hour and can clean 1 square meter of glass per minute. If you know the building is 120m tall at its highest point and 100m tall at its lowest point, and 20m wide, how much should you budget for the contract? Use a line integral of a scalar function to solve. Assume there are no windows to be cleaned on the roof.

In the sequential bargaining game with ∞ <T rounds where player 1 is the first proposer and if the player 2 rejects the offer, the game goes to the second round where they switch roles (the payoff is (s, 1-s) if responder accepts the offer) how do I find the followings?
1. A Nash Equilibrium that is not a SPE.
2. Nash Equilibrium which is different from the first question and which offers the highest possible payoff to the second player amongst all NEs?

A test is given and the average (μX) score out of 100 was only a 53.1, with a SD (σX) of 8.9. Assuming the grades followed a normal distribution, use the Z table or Excel and formulas to find the dividing line (test scores) between the A's, B's, C's, D's, and E's. Starting from the top, the teacher will give the highest 15% A's, the next 10% B's, the next 30% C's, the next 25% D's, and the bottom 20% will receive E's.

The pilot of an airplane executes a loop-the-loop maneuver in a vertical circle. The speed of the airplane is 305 mi/h, at the top of the loop and 450 mi/h at the bottom, and the radius of the circle is 1 180 ft. Note: His apparent weight is equal to the magnitude of the force exerted by the seat on his body. (a) What is the pilot's apparent weight at the lowest point if his true weight is 160 lb? (b) What is the magnitude of his apparent weight at the highest point?

In a volcanic eruption, a 2.40 � 103 kg boulder is thrown vertically upward into the air. At its highest point, it suddenly explodes (due to trapped gases) into two fragments, one being three times the mass of the other. The lighter fragment starts out with only horizontal velocity and lands 253mdirectly north of the point of the explosion.
Part A:
Where will the other fragment land? Neglect any air resistance.
Express your answer using three significant figures.

A −2.60% grade meets a +1.95% grade at station 44+25 and elevation 3386.96 ft, 315-ft curve, stakeout at half stations.
Part A
Tabulate station elevations for an equal-tangent parabolic curve for the data given above.
Express your answers, separated by commas, to six significant figures from lowest to highest elevation.

1.What kind of economic structure (monopoly, oligopoly, pure
competition, ) is the health care drug industry. Explain why.
2.Do you think that companies should always charge what the market
will bear (highest price) or should they base prices on 'ability to
pay' (but still at a profit.)
3. Also, should the government set price limits in health care?
Look for a more recent example related to today’s pricing and
shortages of medical supplies.
