The material for the top and the bottom of the container will cost per square inch, and the material for the sides will cost per square inch. Find the dimensions of the container of least cost: [8 pts] evaluate limx 0. 8x2: [5 pts] compute p100 k=7 k, [8 pts] sketch the curve by eliminating the parameter x = t y = 2t + 3, [20 pts] compute each, using any valid method. Be careful to answer with a number, a function, or a set of functions, as appropriate: 1 2xdx: [8 pts] use a local linear approximation to estimate (1. 97)3, [8 pts] find a value of the constant k that makes this function continuous everywhere f (x) = (cid:26) kx2 x 2.
