Angélica Dass's photography project "Humanae" Select one: Oa. has shown that there are eight dominant human phenotypes. Ob. has revealed that gender is best understood through the binary opposition "feminine" vs. "masculine." Oc. is an attempt symbolically to dismantle the social hierarchies, categories, and divisions of humanity. Od. has shown that, in spite of the vast diversity in the colour of the human skin, humanity can be grouped into six racial categories.

QUESTION 3 Which one is the correct choice to remove the first and last character of a string x? x.substr(0, x.length()-1) x.substr(0, x.length()-2) x.substr(0, x.length()) x.substr(1, x.length()) x.substr(1, x.length()-1) x.substr(1, x.length()-2) QUESTION 4 Which one is the correct choice to print the last character at or before the middle of a string x? For example, if x = "HI", print H. If x = "GREAT", print E. cout << x[(x.length()+1)/2] << endl; cout << x[x.length()+1] << endl; cout << x[x.length()] << endl; cout << x[x.length()-1] << endl; cout << x[(x.length()-1)/2] << endl; cout << x[x.length()/2] << endl;

1. For a cost function C = 100+10Q + Q$^2$, what is the average fixed cost of producing 10 units of output? 2. According to the table below, what is the average variable cost of producing 50 units of output? Q FC VC 0 1,000 0 20 1,000 350 50 1,000 700 90 1,000 1,050 125 1,000 1,400 145 1,000 1,750 160 1,000 2,100 3. Given a cost function C(Q) = 200+ 14Q+8Q$^2$, what is the marginal cost of producing the 10$^{th}$ unit of output? 4. The multiproduct TC function is given by: TC(Q1, Q2)=2-0.5Q1Q2-(Q1)$^2$+(Q2)$^2$. According to this TC function, producing 4 unit of product 2 will decrease the marginal cost of making product 1 by how much? 5. For the cost function C(Q) = 100+2Q+3Q$^2$, what is the total variable cost of producing 2 units of output? 6. What is the value of X in the table below? Quantity Total Fixed Variable Marginal Average Average Average Cost Cost Cost Cost Fixed Variable Total Cost Cost Cost 0 $50 $50 $0 -- -- -- -- 1 $150 $50 $120 $120 $120 2 X 3 7. The company's total cost function is given by TC=1000+14Q-8Q$^2$ + 2Q$^3$. Knowing this, please address all of the following: a. Minimize AVC and calculate the minimal amount of AVC. b.

Question # 4 (20 Marks) Reactive Energy and Material Balance (estimated time 30 min) Formaldehyde is a common preserative agent used in a wide variety of products ranging from pressed wood, cosmetics, embalming fluids and vaccines to list a few examples. It can be made by oxidizing (reacting) methane with air as shown below: $CH_4 (g) + O_2 \rightarrow HCHO + H_2O$ Calculate the components in the exit stream as well as the change in enthalpy for the system (i.e. determine Q). Assume that air is added in 50% excess and the reaction goes to 90% completion. 100 mol/h $CH_4$ 25°C Air Stream 100°C 150°C Components To be determined

Consider a 3-phase induction motor of rating: Output Mechanical Power = PNominal = PRated = PBest Peformance = 10 hp = 7460 W Source Voltage = 208 V (it is RMS and Line-Line Voltage) Cosp Rated = 0.85 rated power factor (lagging) ? = 70% rated efficiency f = 60 Hz, \"Rated speed\" means RPM or rated rotor mechanical speed N = 1170 rev/min (RPM) rated speed APm = 0.5%P which is the mechanical losses at rated speed that includes mechanical friction of the bearings and the windage by blades to cool down the motor Rstator = 0.033 ? stator copper winding per phase resistance P = ? ? = Mechanical Power (Watts) = {Mechanical Torque (N-m)} times {rotor speed (rad/sec)} Or: P = ? ? / (60/2?) =Mechanical Power (Watts)={Mechanical Torque (N-m)} times {rotor speed (RPM)} divide by (975) Calculate: 1) Draw the single-phase equivalent circuit of the motor. 2) Rated (Nominal) stator current (line) for WYE connections of the stator winding, Please note that in the WYE connection, the phase current is equal to the line current. 3) Apparent nominal power SN (power drawn by the stator from the electric source), 3) Active and reactive power absorbed from the mains (electric source) for the nominal mechanical load, 4) Nominal torque and nominal slip, 5) Iron core loss of the stator that produces heat 6) Size of the capacitors in WYE and Delta connection to compensate the reactive power to bring up the power factor to unity.
