3. ### Find two numbers whose difference is 96 and whose product is a minimum?

...product is x * (x - 96 ) = x^2 - 96x Taking the derivative, we get 2x - 96 . Any local minimum or maximum will be found where the derivative equals zero, so 2x...

4. ### For the function f(x) = x3 - 2x2 + 1, find the local maximum value of f.?

...0^2 + 1 = 1 f(4/3) = (4/3)^3 - 2 * (4/3)^2 + 1 = 64/27 - 32/9 + 1 = 64/27 - 96 /27 + 27/27 = -5/27 f(4/3) < f(0) so (0,1) is a local maximum and (4/3,. -5/27) is the local minimum.

5. ### An express train travels 80 kilometers per hour...?

Let DE = distance of express train, DL = distance of local train. DE = 80t DL = 48(t+2) You know the two travel the same distance, so DE = DL 80t = 48t + 96 t = 3 So, the distance each train travels is 240 km.
