A cylindrical can with volume of 250cm, will be manufactured with metal for the top and bottom that costs 0.5cents/cm and a different metal for the sides that cost 0.3cents/cm. If 0 r 5cm, what dimensions (radius and height) will minimize the cost of this can? Vcylinder = rh Surface Areacylinder 2r + 2rh (area of top and bottom plus area of side) 7. Consider the following piecewise function: x > 3 (2x - 3 |x| -x -1 (b) Explain, using both the graph and limit notation, whether this function is continuous. If it is not, describe any types of discontinuities present.
