Suppose you can earn an income of $25 per hour. a) Draw your budget constraint and your indifference curve if you are utility maximizing. Make sure to label the utility maximization bundle. (5 points) b) What is the value of the MRS at the utility maximizing bundle (2.5 points) c) On the graph in part (a), draw another indifference curve and label a point in which the MRS is less than the wage rate. Why is this not the utility maximizing point? (2.5 points)

1. Consider a closed economy with homogeneous labour, constant marginal product of labour, and where firms set prices as a mark-up over unit labour costs. Expressed in constant dollars, output per worker is $15, the opportunity cost of working is $6, and the firms' mark-up is 25%. The size of the labour force is 125. Further, in the medium-run equilibrium the rate of unemployment is 20% and the rate of inflation is 2%. a) What is the level of employment in the medium-run equilibrium ($N_e$)? And the level of real output or income ($Y_e$)? b) Derive an expression for the PS curve. c) Derive an expression for the WS curve. d) Suppose that a permanent increase in aggregate demand causes the unemployment rate to fall by 4 percentage points. What is the new short-run equilibrium level of employment? And of real output? e) What is the impact of this permanent increase in aggregate demand on nominal wages? And on real wages? And on the rate of inflation? Briefly explain. f) Assume adaptive expectations where the expected rate of inflation is equal to the rate of inflation in the previous period. What's the expression for the Phillips curve corresponding to the medium-run equilibrium of part a) above? What happens to the Phillips curve after this increase in aggregate demand? Briefly explain.

The turbine on a ship has a mass of 400 kg and is mounted on bearings A and B as shown. Its center of mass is at G, its radii of gyration are $k_z = 0.3$m, and $k_x = k_y = 0.5$m. If the turbine is spinning at 200 rad/s, determine the vertical reactions at the bearings when the ship undergoes each of the following motions: (a) rolling, $\omega_1 = 0.2$ rad/s: Reaction forces $A_y = $ , $B_y = $ kN (a) turning, $\omega_2 = 0.8$ rad/s: Reaction forces $A_y = $ , $B_y = $ kN (a) pitching, $\omega_3 = 1.4$ rad/s: Reaction forces $A_y = $ , $B_y = $ kN Provide all answers in kN using one decimal place.

Consider the polynomial interpolation for the following data points \begin{tabular}{c|c|c|c|c} x & 0 & 2 & 3 & 4 \\ y & 7 & 11 & 28 & 63 \\ \end{tabular} (a). Write down the linear system in matrix form for solving the coefficients $a_i$ ($i = 0, \dots, n$) of the polynomial $p_n(x)$. (b). Use the Lagrange interpolation process to obtain a polynomial to approximate these data points.
