7. (1 point) Show that $\Phi(u, v) = (7u+4, u-v, 13u+v)$ parametrizes the plane $2x - y - z = 8$. Then: (a) Calculate $T_u$, $T_v$, and $n(u, v)$. (b) Find the area of $S = \Phi(D)$, where $D = \{(u, v) : 0 \le u \le 7, 0 \le v \le 7\}$. (c) Express $f(x, y, z) = yz$ in terms of $u$ and $v$ and evaluate $\iint_S f(x, y, z) \,dS$.

3) An antenna has input impedance equal to 400 $\Omega$ is connected to the television receiver. The bandwidth of the receiver is 6 MHz a) What is the value of the resistor that matches the receiver input impedance and should to be connected across its antenna b) If 600$\Omega$ resistor is connected across the receiver input, what is the equivalent noise voltage applied to the receiver input. [assume room temperature =293K] c) If 300$\Omega$ resistor is connected across the receiver input with input power signal equal to 2mW, what is the signal to noise ratio at the input of the receiver. [assume room temperature =293K] d) If 500$\Omega$ resistor is connected across the receiver input with external noise equal to zero, what is the value of the minimum input voltage signal at the receiver input? [assume room temperature =293K]

Please explains of this examples, this is the questions what was your opportunity cost and explain how you made that decision using the opportunity cost concept. Give an example from one of the choices you made among alternatives this week. What was your opportunity cost? Explain how you made that decision using the opportunity cost concept. Why would a hot dog vendor on a New York street corner lower the price of dogs late in the day? Why would a poor family in a developing country chose to send a 10-year-old to work in a factory rather than to school, even though they know that being able to read and write would offer the child better options for the future? What do so many more inventions and innovations come from western countries where property rights are secure than from developing and communist countries where they are not? Why are people in some parts of the world willing to work for $1 per day and in the U.S. employers often have trouble finding people willing to work minimum wage jobs?
