Compute the transfer function $H(s) = \frac{N(s)}{D(s)} = H_1(s) \cdot H_2(s)$ of the\circuit in Fig. P1a. Formulate its denominator polynomial in\the form $D(s) = s^2 + 2as + \omega_0^2$, with numeric values for $a$ and $\omega_0^2$,\and obtain the poles of the transfer function of the circuit.\ 1b.- 25 points: Modify the values of $R_1, C_1, R_2, \& L_1$ in Fig. P1a\to design a passive second order band-pass filter.

1) Short 1-2 sentences explaining what you believe to be true so I can determine what is the null and alternate hypothesis. Without this information I will not be able to distinguish between your null and alternate hypothesis. 2) List your dependent variable (just one). This should be listed after your IV in your hypotheses. 3) List your independent variable (just one). This should be listed before your DV in your hypotheses. 4) Construct a null hypothesis statement using your listed DV and IV. Remember that the DV is the constant variable and the IV is the predictor variables. For example, you may believe that changes in the IV causes changes to the DV. For example (don't use this one), you may believe that that the more hours someone studies per day, the better final exam grade will be. Your DV is final exam grade. Your IV is number of hours studying per day. The DV is the final exam grade because that is what you are measuring. You could create another IV and say that sleep also may impact exam grades. So, sleep could be another IV. As you can see, there may be many IVs used in research, but the DV remains constant. Please go back and review prior lectures about alternate and null hypothesis before constructing yours. Note the importance of using statistically significant language in your hypotheses. You can create any DV and IV you would like. However, they must be measurable and specific. Null and Alternate Hypothe... (16.79 KB) Hypothesis.mp4 (1).zip (36.06 MB)

9. Ellison Seafood Company ships fresh seafood to customers in a nearby city. The logistics manager has identified three shipping alternatives. Table below shows the fixed costs and variable costs for each alternative. (6 points) Fixed cost Variable cost COMMON CARRIER None $750 CONTRACT CARRIER LEASING $5,000 $300 $21,000 $50 Figure below shows the total cost (fixed cost + variable cost) of each alternative as the number of shipments increases. By looking at the graph, calculate the indifferent points and explain company optimal decisions based on the number of shipments. $40,000 Common $35,000 $30,000 $25,000 Lease $20,000 $15,000 Contract $10,000 $5,000 $0 5 15 25 35 45 55 65 75 Number of shipments

14. You have shown the following on your last quiz: dH = $C_p dT + \left[ V - T \left( \frac{\partial V}{\partial T} \right)_p \right] dp$ Based on the definition of residuals, this means that: $H - H^{IG} = \int_{T, P = 0}^{T, P} \left[ V - T \left( \frac{\partial V}{\partial T} \right)_p \right] dp$ You instead want to solve for enthalpy based on a change in volume, rather than a change in pressure (which is what is convenient from the previous equation). Based on the definition of enthalpy, prove the following: $H - H^{IG} = RT(Z - 1) + \int_{T, V = \infty}^{T, V} \left[ T \left( \frac{\partial P}{\partial T} \right)_V - P \right] dV$
