Need help with this one is really confusing.

Find the effective rate that corresponds to the given nominal rate. 13% compounded semiannually The effective annual yield is (Round to three decimal places as needed.)Suppose products Aand B have demand and supply equations that are related teeach other. If qA and us are the quantities produced and sold chat and B, respectively. and [an and p3 are their respective prim, the table below Show the demand equations and the supply equations. Eliminate q.\" and (13 to get the equilibrium prices. demand equations supply equations \"=5'pA+pB %='7*4PA'3PB QB=25+PACDB QB='5'3PA'4PB The prices are pA=S and p3 =522'56 A (Round to the nearest cent as needed.)
