متن کاملUnm - Pnm Statewide Mathematics Contest Xlvi - Solutions
The question is to find 2A+H +N + S. If we add the first and the third equations in the system and subtract the second equation from the result we obtain 2A+H +N + S = 21 + 18− 25 = 14. 2. If f(x) = x + 6x + 12x+ 6, solve the equation f(f(f(x))) = 0. Answer: Note that f(x) = (x + 2) − 2. Thus f(f(x)) = ((x + 2) − 2 + 2) − 2 = (x + 2) − 2 and f(f(f(x))) = ( (x+ 2) − 2 + 2 )3 − 2 = (x+ 2) − 2. So...

متن کاملXlvi. the Hagedorn-jensen Method Applied to Various Sugars. Relation of Reducing Power To
THE increasing knowledge of sugar structure and its physiological significance has prompted a close scrutiny of the methods for the quantitative analysis of reducing sugars. Most of the methods are based on the oxidation of the sugars. The amount of oxygen consumed permits a comparison of the oxidising reagents. The products of oxidation are in most instances not uniform, thus the oxygen factor...
