A 57-year-old man is brought into the emergency department with severe trauma due to a gunshot wound to the upper right quadrant of his abdomen. He is bleeding profusely and needs an immediate transfusion of blood. 1. Since this is an emergency and there is no time to do a blood typing screen, which blood type can you give this patient? 2. Why can this blood type be used?
Function [estimate, trueError] = myCosh(x, N) estimate = 0; trueValue = cosh(x); for n = 0:N estimate = estimate + (x^(2*n)) / factorial(2*n); end trueError = abs((trueValue - estimate) / trueValue); end

f) The Bellman-Ford algorithm is an algorithm that computes shortest paths from a single source vertex to all the other vertices in a weighted digraph. The bottom-up implementation relaxes each of the edges up to $|V|$ rounds. Consider the following graph, Bellman-Ford is used to obtain shortest paths from z to u, v, x and y. u $\infty$ -2 v $\infty$ 0 1 2 3 4 5 4 -2 z 0 0 0 0 -3 u $\infty$ 4 4 -3 v $\infty$ $\infty$ a 8 x $\infty$ 3 1 y $\infty$ $\infty$ b 6 3 x $\infty$ 2 y $\infty$ The 1st two rounds of relaxations are shown in the table above. Which of the following is true? i) a = -2 and b = 1 ii) a = -2 and b = 5 iii) a = 1 and b = 1 iv) a = 1 and b = 5 v) Neither of the above
A hydrogen atom emits a photon when its electron shifts from a higher energy level to a lower one. Suppose that one atom emits a photon whose wavelength equals 656 nm. If the energy levels are defined by the quantum number $n$ (where $n = 1, 2, 3, \dots$), what was the final value of $n$? \begin{tabular}{|c|c|} \hline $n$ & $E_n$ (eV) \\ \hline 1 & $-13.6$ \\ 2 & $-3.40$ \\ 3 & $-1.51$ \\ 4 & $-0.850$ \\ 5 & $-0.544$ \\ \hline \end{tabular}
