Match the description to the correct form of strengthening This is the only technique on this list that can be used to strengthen polymers This is the only strengthening technique we discuss that creates two separate phases within a metal. The boundaries between the phases act as barriers for dislocations This strengthening method uses the disorder at the crystal boundaries to block dislocation movement This strengthening technique doesn't require heating, but is not often used deliberately because it can make the material very brittle. Check Annealing is a multistage process where metals are heated and then cool Precipitate hardening Annealing Work hardening Crosslinking Solid solution strengthening Grain size refinement

4.) (25 points) Suppose a competitive firm has short run costs $C(Q) = Q^2 + 8Q + 25$. a. (10 points) Solve for the other cost curves: MC, AC, AVC, and AFC. b. (5 points) Solve for the output level that minimizes average cost and calculate the cost at this output level. c. (10 points) Assume the market price is $10 at the output level in b. Should the firm shut down in the short run? Show how you know.
