Question 2: Mr. Simon collects the following details about his company's operations: Pie price \( =\$ 10 \) Pie demanded \& sold (per week, in thousands) \( =18 \) Unit pie processing cost (per pie) \( =\$ 2.05 \) Unit cost fruit filling (per pie) \( =\$ 3.48 \) Unit cost dough (per pie) \( =\$ 0.30 \) Fixed cost \( =\$ 12 \) a. Calculate by hand the financial results relevant to Mr. Simon, say: revenue, processing cost, ingredients cost, total cost and profit, assuming that there is no tax. b. Create an excel sheet (labeled Sheet_Q2) modeling Simon Pie Company's profit model.

Sketch the graphs of the following parabolas showing the turning point and intercepts with the axes. Also write down the domain and range of each graph. 1. \( y=-(x-3)^{2}+4 \) 2. \( y=\frac{1}{2}(x+2)^{2}+2 \) 3. \( y=3(x+3)^{2}+4 \) 4. \( y=-2(x-1)^{2}+2 \)

1. (i) \( \frac{x}{2}+\frac{2}{x} \)

Q9. A new drug called Weloveochem is being tested for its enantiomeric purity in the labs. The enantiopure specific rotation of \( (-) \)-Weloveochem at \( 25^{\circ} \mathrm{C} \) is known to be \( -38^{\circ}\left([\alpha]_{\mathrm{D}}{ }^{25}\right) \). a) What is the observed rotation for a solution of Weloveochem containing \( 0.96 \mathrm{~g}(+) \)-Weloveochem and \( 0.01 \mathrm{~g}(-) \)-Weloveochem in 100 mL of solvent? Assume a 1 dm cell.
