The point P(9, 5) lies on the curve y = \sqrt{x} + 2. If Q is the point (x, \sqrt{x} + 2), find the slope of the secant line PQ for the following values of x. If x = 9.1, the slope of PQ is: .1662 and if x = 9.01, the slope of PQ is: .1665 and if x = 8.9, the slope of PQ is: and if x = 8.99, the slope of PQ is: .1665 Based on the above results, guess the slope of the tangent line to the curve at P(9, 5).

(8) You are the manager of a firm that specializes in selling a product with very few substitutes. Your goal is to determine the amount to produce each month in order to maximize profits. The total benefits (revenues) and costs of producing various quantities are given in the first three columns of the table on the next page. + Q B(Q) C(Q) NB(Q) MB(Q) MC(Q) 0 0 50 1 90 60 2 170 90 3 240 140 4 300 210 5 350 300 a) Fill in the table. b) Graph the marginal benefit and marginal cost curves. Label everything. Tip: copy the table into Excel. You can do the calculations and graphing there if that's easier. c) If you can only produce in whole units, what quantity maximizes net benefits? (note: report your answer as an integer) Illustrate this on your graph. d) Explain the logic behind your answer to part (c).

5-10. The value of $k_L$ for oxygen in a particular gas transfer system that will be used to inject ozone ($O_3$) into a water supply has been estimated to be 0.015 cm/s. The ozone generator upstream of the gas transfer process converts 10% of the $O_2$ in the incoming air into $O_3$. (a) If the water to be treated is at 25°C and contains 5 mg/L $O_2$(aq) and no ozone, estimate the rela- tive fluxes (on a molar basis) of $O_2$ and $O_3$ into the solution when the gas and liquid first come into contact. Assume that $m = 0.5$ and that the vast majority of the resistance to gas transfer is in the liquid phase for both species. Also assume $P_{tot} = 1.0$ atm. The diffusivity of $O_3$ in water at 25°C is $1.30 \times 10^{-5}$ cm²/s. (b) If $k_g/k_L$ is 20 for both $O_3$ and $O_2$, what fraction of the resistance to gas transfer resides in the liquid for each species? (c) Do you think that the transfer of ozone would be enhanced, diminished, or not altered if the water were deaerated (so that the DO concentration were essentially zero) prior to the treatment process?
