1. ABC company can produce any quantity of cars with a fixed cost of 1 billion USD and marginal cost of 10,000 USD. It operates in two markets, each of which has the following demand function: \( \mathrm{P}_{\mathrm{E}}=30-\mathrm{Q}_{\mathrm{E}} / 50 \) (European market) \( P_{A}=24-Q_{A} / 100 \) (Asian market) Price and costs are in thousand USD and quantity is in thousand cars. a. Calculate the quantity and price that maximise profit in each market. What is ABC's maximum proft? b. If \( A B C \) is required to sell at the same price in both markets, what will its maximum profit be?

Exercise 3.1: Derive the moment generating function of the multivariate normal distribution $N(\mu, \Sigma)$.
Shaft Rotates @ 500 rpm f = 48f 500 rpm = \frac{500}{60} Hz = 8\frac{1}{3} Hz. 10kw 20kw A 400 400 400 rc = 70 mm = 0.07 m \Gamma_D = 90 mm = 0.09 m \Gamma_E = 200 mm = 0.2 m \tau_{all} = 50 MPa \phi_{AB} min ? So: T_E = \frac{30}{2\pi(8\frac{1}{3})} = 573.2 N.m Corresponding Forces: F_E = \frac{573.2}{0.2} = 2866 N Gears C \frac{1}{3} D : T_C = \frac{20 kw}{2\pi(8\frac{1}{3})} = 381.99 N.m F_C = \frac{381.99}{0.07} = 5456.96 N
Assignment-I 1) Calculate following series (using single precision and double precision) and compare the result with exact value (for x=0, 10, 20, 30). Analyze the results. $e^{-x} = \sum_{n=0}^{\infty} \frac{(-1)^n x^n}{n!}$ $e^{-x} = \sum_{n=0}^{\infty} s_n = \sum_{n=0}^{\infty} (-1)^n \frac{x^n}{n!} \text{ for } s_n = -s_{n-1} \frac{x}{n}$ Calculate $e^x = \sum_{n=0}^{\infty} \frac{x^n}{n!}$ and inverse it Use Truncation Value = $10^{-5}$ for SP and $10^{-12}$ for DP Assignment-I 2) Consider following series (using single precision and double precision): Consider finite series (N is finite): $s_1 = \sum_{n=1}^{N} \frac{1}{n}$ $s_2 = \sum_{n=N}^{1} \frac{1}{n}$ $s_1 \neq s_2$ (roundoff errors) • Using single precision and N=10$^6$, show $s_1 \neq s_2$ • Using double precision $s_1$ exactly equal to $s_2$ for N=10$^6$ • But for N=10$^8$ double precision $s_1$ differs from $s_2$
