PROBLEM #3: (follow up to the car jump-starting example in class) $$R_J$$ $$r_1$$ $$r_2$$ $$R_S$$ $$R_J$$ $$E_1$$ $$E_2$$ The above circuit represent the situation of jump starting a car with a weak battery. The right part of the circuit has a weak battery ($$E_2 = 10$$ V, internal resistance $$r_2 = 0.1 \Omega$$) connected to the starter (resistor $$R_S = 0.15 \Omega$$). The left part is the other car with a good battery ($$E_1 = 12$$ V, $$r_1 = 0.02 \Omega$$), and two jumper cables ($$R_J = 0.0025 \Omega$$) are used to connect the good battery to the bad one. (a) If only the week battery is connected to the starter, what is the current through the starter? (b) Now if the other car is connected using the cables, what is the current through the starter? Note: You will need to set up the problem with Kirchhoff's rules to do part (b), and in this problem you DO need to solve the equations and find the current through $$R_S$$.

Text: Part 2 - Answer the following questions Question 2 (30 marks) mixed cost, using miles as the activity level. Miles Driven 10,000 8,000 9,000 7,500 Total Cost $15,000 13,500 14,400 12,500 January February March April Required: 1. Compute the variable and fixed cost elements using the high-low method. 2. If it is estimated that 12,000 miles will be driven in May, what is the expected total cost for May? (7.5 marks) BXYZ Company sells its only product for $40 per unit. Its total fixed costs are $180,000 per annum. Its CM ratio is 20%. XYZ plans to sell 16,000 units this year. Required: 1. Calculate CM per unit and the variable cost per unit. 2. Calculate the break-even point in unit sales and in dollar sales. 3. Calculate the unit sales and dollar sales required to achieve a target profit of $60,000 per year. 4. Assume that the company is able to reduce its variable costs by $4 per unit and accordingly the sales price per unit will also be reduced by 5%. a. Calculate the company's new break-even point in unit sales and in dollar sales. b. Calculate the dollar sales required to achieve a target profit of $60,000. 5. In your opinion, do you think the company would be better off with the assumed reductions? (12.5 marks) Why?

1. (i) Find the volume V of the solid bounded by $y = x^2$ and by the planes $y + z = 4$ and $z = 0$ by setting up a triple integral with z as the innermost variable. (ii) Set up a triple integral for finding the volume of the above solid with the innermost variable as $x$. 2. Change the equation from cylindrical to rectangular coordinates and sketch the graphs in the xyz-coordinate system: (i) $z = 4r^2$ and (ii) $r = 4 \sin \theta$. 3. (i) A solid E lies between the paraboloid $z = 24 - x^2 - y^2$ and the cone $z = 2\sqrt{x^2 + y^2}$. Using cylindrical coordinates, find volume of E. (ii) Set up triple integrals to find the centroid of E (i.e., center of mass if the density is a constant).
