concentration of a drug t hours after being injected is given by C(t)= 0.3t / t2 +68 Find the time the concentration is ata maximun. Give your answer accurate to at least 2 decimal places. b) A farmer wishes to enclose a rectangular field. Three of sides will be visible from the street. so be will use a nice looking fence for those sides, costing $100 per foot. Howevwe, the north side is only visible to a farmer, so there he will use brushes costing $40 per foot. he wants to spend $8400 for the materials, what are the dimensions of the field that yield the largest area?
