Problem 2 Let $p$ and $q$ be positive constants. Consider the following minimization problem $\min f(x, y) = px + qy$ s.t. $g(x, y) = 5xy - x^2y^2 = 4$ (a) Solve the first order necessary conditions of the problem. (b) Verify that the point you have found in (a) solves the minimization problem. (c) How does the optimal value of $f$ changes if the parameter $p$ increases?

You stand on a bathroom scale, the spring inside the scale compresses 4.79 mm, and it reads your weight as 750 N. Now if you fall from rest onto the scale from a height of 0.23 m, what does the scale read at its peak? Round to the nearest Newton. HINT 1: When standing, you are at static equilibrium. HINT 2: The scale will have its peak reading when the scale is most compressed.

For the periodic signal shown above where time t is in sec, a) determine the exponential Fourier Series coefficients of the signal; b) use the result of part a) to determine the exponential Fourier series of the signal: c) use the result of part b to generate in MATLAB the signal shown in terms of its Fourier Series expansion. Show a diagram over the same time interval above and make sure to include the code used to generate the plot (NO CODE = NO CREDIT).d) Use MATLAB to generate a spectral plot showing separately magnitude and phase as a function of frequency. 2. Apply the signal of Prob. 1 to the following systems specified in terms of the impulse response: a) , b) , c) , d) . For each of these four cases, determine and plot using MATLAB as a function of and as a function of . For each of these cases determine the output and plot as function of time for each of the four impulse responses.
