Suppose 1 U.S. dollar can be traded on the foreign exchange market for 1.5 Brazilian reals, 1.25 Swiss franc, or 0.75 British pound.  a.   How many dollars can 1 British pound purchase? (4 points) b.   If the Brazilian real depreciates by 0.10 reals, how many dollars can 1 Brazilian real purchase? (4 points) c.   Everything else held constant, if U.S. demand for Swiss chocolate increased what would we expect to happen to the Swiss franc in the long run? (2 points) Answer parts a, b, and c in the space provided. Show your work for parts a and b (i.e. 1 + 2 = 3; 2/4 = 0.5).

Problem 4b Refrigerant-134a flows through a 30 mm diameter, 15 m long pipe at 15 m/s. The fluid enters the pipe at 350 K, and the surface of the pipe is measured to be 290 K.   Assume the following properties for the refrigerant: ρ (kg/m3) ν (m2/s) k (W/m-K) Pr 1116.8 0.1323 x 10-6 0.0718 3.2   Determine the average convection coefficient (W/m2K)

Considr thr following relation schema R=ABCDEF with the following FDs cover: cover (f)= { ABC->F, ABC->E,ABC->D,F->D,AF->E,AF->C,AF->B ,AE->B, ACE->F, ACE->D} Decompose the the reltion schema R into several relation schemas in BCNF using the decomposition algorithm
