Paperback. A company estimates that the marginal cost associated with producing x paperback books per week is C'(x) = 14.25 - 0.0016x If the weekly fixed cost of producing paperback books is 669, find an expression for C(x), the weekly cost of producing x paperback books. : C(x) = Tin Can. Suppose a tin can in the shape of a right cylinder including a lid producing a cylindrical container of volume 25 cm . The cost of producing the top and bottom of the can is 37 cents per cm2 and the cost of producing the side of the can is 24 cents per cmz. Hint: the area of the side is 22m. (a) The cost function is Note: Enter the cost function in terms of the radius r only. The symbol at is in the Calcpad on the right in Symbols. C(r) = ' I (b) The dimensions of the tin can that has the minimum cost are Note: Enter your answers as a fraction a/b or as a decimal number rounded to 4 decimal places without units. r= cm h = cm Air Pollution The amount of nitrogen dioxide, a brown gas that impairs breathing, present in the atmosphere on a certain May day in the city of Long Beach is approximated by A(t)-$+31 (0
