Question 1 (2+2+3+3+3+3=16 points) Fix A ∈ Rm×n , b ∈ Rm , and c ∈ Rn . (a) Write down the KKT conditions for the following problem, on the variable x ∈ Rn : min cT x Ax = b ; x ≥ 0. (1) (b) Write down the KKT conditions for the following problem, on the variable (λ, s) ∈ Rm+n AT λ max λT b + s = c; s ≥ 0, (2) Show that both the KKT conditions associated with both problems are identical. (c) Given x, s ∈ Rn , define the matrices X = diag(x1 , . . . , xn ), S = diag(s1 , . . . , sn ), and the vector

matters relate to all characteristics of personal and family life. In order to better manage financial problems, everyone should have a financial plan. Furthermore, in setting goals we can make a statement of the financial plan. Two financial problems that I face personally, and as the head of house hold, are saving money and too much debt. When looking at savings, I see a financial problem as far as my short term and long term goals. It would be ideal to save money for the short term for things

overcome our problems. The first step is the most imperative and that is to identify the problem in details and what you hope to gain from solving this problem. “We cannot solve a problem unless we define it well” (kirby & goodpaster, , p. 288). Secondly, know your alternatives, your other options and of course your limitations. Thirdly weigh your alternatives in terms of their advantages and disadvantages. Fourth make your choice on what solution you will use to overcome your problem. Last but

stress management How does EFT work? There are several explanations of how EFT works. The creator of the technique and many practitioners attribute its effect to balancing the energy in meridians, as in acupuncture, in relation to a specific problem. Some neurological explanations for its efficacy include balancing the activity of parasympathetic and sympathetic branches of our nervous system, and facilitating “adaptive information processing”. The areas of skin associated with acupressure points

How does the math I am learning in the classroom relate to the real-world? What does a good problem solver do? What should I do if I get stuck solving a problem? How do I effectively communicate about math with others in verbal form? In written form? How do I explain my thinking to others, in written form? In verbal form? How do I construct an effective (mathematical) argument
