Us savings bond: (8pts) solve 7e3t = 8e2t for t. 1 x x x: (12pts) the graph of the function y = f (x) is given on the right side. 2: (10pts) suppose the population in the united states follows the model p (t) = of years since 1815). (a). What is the maximal capacity of us population as the model assumes. 1 + 399e 0. 04t (million) ( t is the number (b). Based on this model, in which year would the us population be 200 million? (c) sketch the graph of p (t) against t indicating the con- cavity and the point of diminishing returns. 400 t: (12pts) find the derivatives of the following functions: (a). f (t) = 3t2 + 12.
