QUESTION 16 Given the first-order partial differential equation $\frac{\partial u}{\partial x} - \frac{\partial u}{\partial y} = 0$, the change of variables $\xi = x + y$ $\eta = x - y$ will transform the original differential equation into: $\frac{\partial u}{\partial \xi} = 0$ $\frac{\partial u}{\partial \eta} = 0$ $\frac{\partial u}{\partial \xi} + \frac{\partial u}{\partial \eta} = 0$ $\frac{\partial^2 u}{\partial \xi \partial \eta} = 0$
You and a team of interns have been hired by the Social Security Administration to evaluate when Social Security assets will decrease most rapidly. You and the interns have been provided a projection of year-end assets in the Social Security trust funds, in trillions of dollars, as follows A(t) = 0.0000329t^3 - 0.00450t^2 + 0.0613t + 2.37 where t represents the number of years since 2000 and 0 ? t ? 50. Find the time t when Social Security assets will decrease most rapidly. Approximate the date that this will occur. Further, as part of your analysis, the SSA has asked you comment on retirement population, population growth, and retirement trends in terms of the average age that workers are retiring. This part of your analysis will require you to look up some retirement statistics on your own. Please provide insight about retirement trends and growth as it might relate to your answer to the problem above.
