• Exercise #1 or the utility function of a consumer: U = f(x, y)=3(X^2)Y 1. Calculate the marginal utilities of X and Y; 2. Determine the marginal rate of substitution; 3. Determine the demand functions of X and Y, 4. Determine the share of income that the consumer spends the acquisition of good X, then that devoted to the purchase of good Y.

Using the principle of current mirrors, determine the currents (I1, I2, .....,I10) and the voltages (V1, V2, ...., V10) for the following circuit. We neglect the base currents (𝜷 ≫ 𝟏). On gives |VBE|=0.7 V We assume for reasons of symmetry that I9=I10 =I8/2 and I5 =I 6=I4
