##### Problem 6. Explain what is wrong in the following proof and write a correct version of it_ For any real number b such that 1 < b < 5, prove that b3 6b2 + 5b < 0.Proof Suppose that 1 < b < 5. b3 6b2 + 5b = b(62 6b + 5) < 0 sO, since b > 0 we have b2 6b + 5 < 0. But we notice that 62 _ 6b+5 = (b - 1)( _ 5). Since 1 < b 5, we know that b =1 > 0 and b - 5 < 0 s0 indeed b2 _ 6b + 5 = (6 - 1)(b _ 5) < 0.

##### An ore sample is analyzed for chromium by Atomic AbsorptionSpectrophotometry (AAS). Afinely ground dried sample weighing 4.750g is fused with 4g ofNa2O2 in a zirconium crucible.The fused melt is dissolved in 65 mL of water, 5 mL HNO3 and 5 mLof 10% H2O2 are added, andthen the solution is diluted to 100 mL. 1.00 mL aliquot of thissolution is again diluted to 100 mLbefore the absorbance is read with the AAS. From comparison withstandards, it is found thatthe final solution contains 88 ug Cr/mL. Wh
