Suppose there are two loans with one interest rate at 4% and a second loan at 5%. The manager writes the rst part of the formula for the new interest late as E(4ln{5) + 5|n(4)) Which of the following is equivalent to the manager's expression? 0 640000 (3 9399 0 1649 O 9625+91024 () e320000 C) 0 0 320000 (3 954000:) Profit. Suppose the profit of a product is modelled by the function f(x) = 2x3 - 27x2 + 108x + 3 The absolute maximum value of f(x) on [2,5] is Of = 2 Of = 12 Of = 118 Of = 138 Of = 3 Of = 111 O There is no maximum Of = 5
