Discussion Prompt About one baby out of every 600 born in the U.S. has Down's syndrome. Many of these children are born with fatal physical conditions that can cause quite a bit of pain and suffering. For instance, a baby with Down's syndrome could be born with part of their vital organs missing, intestines might be blocked, and their heart might not pump properly. Surgery is often required for these infants to survive beyond the first few days of life. Parents must decide whether to allow surgery to save the child, who may end up requiring costly long-term care and services for life withholding permission, thus causing the child to die. Also, we will be concerned with which course of action would be the right one, not with who has the right to decide. Using one of the moral theories from this course to bolster support for your view, do your best to definitely answer whether it is immoral for the parents to withhold surgery?

Solve the following optimal apartment location problem using optimization in differences Suppose you narrowed your apartment list to four. Those apartments are in four locations: Location A, Location B, Location C, and Location D. Location A is in the city, where your job is. Location B amounts to 7 hours more of commuting per month than Location A. Location C amounts to 7 hours more of commuting per month than Location B, and Location D amounts to 7 hours more of commuting per month than than Location C. In turn, similar apartments in Location B rent for $145 less per month than apartments in Location A, apartments in Location C rent for $145 less than in Location B, and apartments in Location D rent for $145 less than in Location C. Suppose the value of your time is $22 per hour. For simplicity, assume rent and the opportunity cost of your time commuting to work are the only factors influencing the location in which to rent an apartment. Using optimization in differences and Location A as your starting point. You should rent an apartment in Location D Suppose you currently rent an apartment in Location B. By moving to optimize, you change your net benefit by $ 18. (Enter your response as an integer.)

Consider a causal LTI system. When the input to the system is $x[n] = \frac{-1}{3} \left(\frac{1}{2}\right)^n u[n] - \frac{4}{3} (2)^n u[-n - 1]$, the z transform of the output is $Y(z) = \frac{1 - z^{-2}}{(1 - \frac{1}{2}z^{-1})(1 - 2z^{-1})}$ a) Find the z transform of the input signal. b) What are the possible choices for the ROC of $Y(z)$? c) What are the possible choices for the linear constant coefficient difference equation used to describe the system? d) What are the possible choices of the impulse response for the system?
