Question content area Part 1 For the following scenario, decide whether you agree or disagree and explain your answer. If the elasticity of demand for cocaine is minus 0.20 and the Drug Enforcement Administration succeeds in reducing supply substantially, causing the street price of the drug to rise by 50%, buyers will spend less on cocaine. Part 2 A. Disagree: When price increases and demand is inelastic, total revenue will rise. B. Disagree: When price increases and demand is elastic, total revenue will rise. C. Agree: When price increases and demand is elastic, total revenue will fall. D. Agree: When price increases and demand is inelastic, total revenue will rise.

Declaration: Should it become evident that I copied work from someone else or any other source, I accept that no marks will be earned for this work and I submit myself to disciplinary measures to be taken against me. ETB115D Assignment 3 Semester 1 - 2024 1. Consider the series regulator in Figure 1. The regulator should be designed to supply a load with 10 V and 80 mA. Assume transistor $Q_1$ has $\beta = 25$ and $V_{BE} = V_D = 0.7$ V. Use proper analysis techniques and assumptions and answer the following questions. 1.1. Assuming the voltage drop across the limiting resistor is 0.6 V, calculate the Zener voltage required. 1.2. If the Zener requires a 2-mA biasing current, calculate the DC current that enters the regulator ($I_{DC}$). 1.3. Calculate the value of $R_1$ to bias the transistor and the Zener diode (Assume the regulator has an average DC input of 15 V). Select an appropriate E12 value from the resistor table. 1.4. If transistor $Q_1$ switches on at 0.7 V and the output limit is 100 mA, calculate the value of $R_L$ and select an appropriate E12 value from the resistor table. 2. Consider the series regulator in Figure 3. The regulator should be designed to supply a load with 9 V and 100 mA. The Zener diode used has a 2 V Zener voltage, transistor $Q_1$ has $\beta_1 = 24$ and $V_{BE} = V_D = 0.7$ V, transistor $Q_2$ and $Q_3$ has $\beta_2 = \beta_3 = 400$. Use proper analysis techniques and assumptions and answer the following questions. 2.1. Calculate the minimum load that may be attached to this regulator. 2.2. Assuming a current of 100 $\mu A$ in $R_5$, calculate resistors required in the feedback to provide 9 V output. Select appropriate E12 values from the attached resistor table. 2.3. If the Zener requires a 4-mA biasing current, calculate the DC current that enters the regulator. 2.4. Calculate the value for $R_4$ to bias the Zener diode and transistor $Q_1$ (Assume the regulator has an average DC input of 15 V). Assume a 0.6 V drop across the limiting resistor ($R_4$). Select an appropriate E12 value from the attached resistor table. 3. The following measurements were taken in the lab: $\circ$ The nominal load voltage: 8.2 V $\circ$ The open circuit load voltage: 8.3 V $\circ$ The regulator input ripple voltage: 1.5 V $\circ$ The maximum regulator output voltage: 8.22 V $\circ$ The minimum regulator output voltage: 8.16 V Calculate: 3.1. The load regulation. 3.2. The line regulation.

Texts: Suppose that you are a manufacturer that uses parts that can be made in-house or bought from a foreign supplier upstream. Denote by 𝑞𝐼 the quantity manufactured in-house, by 𝑞𝐹 the quantity purchased from the foreign supplier, and by 𝑞 = 𝑞𝐼 + 𝑞𝐹 the total quantity. The cost of manufacturing in-house is 𝑐𝐼(𝑞𝐼) = 15𝑞𝐼 while the cost of purchasing from the foreign supplier is 𝑐𝐹(𝑞𝐹) = 116(𝑞𝐹)². a. From which option will you initially source from? Why? b. How many units will you acquire before switching suppliers? c. What is the minimum cost 𝑐(𝑞) of acquiring 𝑞 units for any arbitrary quantity 𝑞? 2. (10 points) A specific tariff is a tax placed on each unit of a good purchased from abroad. For example, if a specific tariff of $4 is placed on each kilogram of aluminum imported from Canada, then the cost of importing each aluminum from Canada is the original cost plus the $4 tax per unit imported. Consider the suppliers and costs from Question 1 but suppose that a specific tariff of $4 per unit is imposed on each unit imported from the foreign supplier. a. From which option will you initially source from? Why? b. How many units will you acquire before switching suppliers? c. What is the minimum cost 𝑐(𝑞) of acquiring 𝑞 units for any arbitrary quantity 𝑞? d. How do these costs compare to your answer to Question 1(c)? e. What does your answer to part (d) suggest regarding how tariffs affect domestic businesses with international supply chains?

Texts: Food security exists when all people at all times have physical and economic access to sufficient, safe, and nutritious food that meets their dietary needs and food preferences for an active and healthy life. Explain strategies that the government can implement to improve national and household food security. (10) A 12-month-old boy child, Chris Jen, was brought to Tses Clinic for the first time with a history of watery diarrhea, poor appetite, weight loss, and cough for 12 days. On examination, the child appears lethargic and irritable. The child is conscious, has severe dehydration, an axillary temperature of 34.8°C, a respiration rate of 39 breaths per minute, a mid-upper arm circumference (MUAC) of 11 cm, a weight-for-length z score below -3, bilateral pitting edema, and severe wasting. The child also has skin eczema and discharging eye exudates. The child failed the appetite test. There are no other complaints. Answer the following questions based on this scenario. 2.1 Outline questions that you will first ask the mother to rule out danger signs. (5) 2.2 What is the classification of this child according to the scenario? (Base your answer on the IMCI guideline). (2) 2.3 Explain the in-patient management of this child according to your answer in 2.2. (1x15=15)
