5. Draw a set of coordinate axes on a piece of graph paper. Label the x axis“Output” (0 to 20 units) and the y axis “Cost” (0 to 20 units). Plot the following (x, y) points on your graph: (0, 4); (2, 6); (4, 7); (7, 8); (9, 9); (11, 11); (13, 14). Connect these points with a smooth curve and label it “Total Cost.” Working from this curve, construct a total fixed cost curve and total variable cost curve...

4) Draw the titration curves for the amino acids Lysine and Alanine. Be sure to label your axes. (5 pts) a) Identify the pKi, pK and pKR (if relevant) for each amino acid. b) Identify the buffering region around pKR for arginine c) Identify the pl of each amino acid d) Draw the structure of the primary chemical species in each pH region of the titration curve.

For each of the following examples, draw a representative isoquant. Make sure to label the axes. Explain briefly why you drew each isoquant the way you drew it. a) A firm finds that it can always trade two units of labor for one unit of capital and still keep output constant, regardless of how many units of labor or capital have already been used. b) A firm needs either cats or dogs to produce its output. Cats and dogs don’t...
