Infection Handout The questions on the handout correspond to Frontline's Hunting the Nightmare Bacteria. http://www.pbs.org/wgbh/frontline/film/hunting-the-nightmare-bacteria/ 1. How did Ricci bring NDM-1 into the United States? Is there a similarity with COVID 19? Explain. 2. What does enhanced contact isolation mean?

Use graphical methods to solve this linear programming problem. Minimize \( \quad \begin{aligned} z=4 x+7 y \\ \text { subject to: } \\ \begin{array}{rl}x-y & y \\ 3 x+2 y & \geq 18 \\ x \geq 0, y & \end{array}\end{aligned} \)

A Su un treno sono presenti 122 passeggeri nella prima carrozza e 56 nella seconda. Quanti passeggeri in tutto? Se alla prima fermati scendono 45 passeggeri, quanti ne restano sul treno?

Find all solutions of the equation in the interval \( [0,2 \pi) \). \( -\cot x-1=\csc x \) Write your answer(s) in radians in terms of \( \pi \). If there is more than one solution, separate them with commas. \( x=\square \)

Hallar la ecuación de la parábola con vértice en el origen y foco en \( (3,0) \) a. \( Y^{2}=21 X+5 \) b. \( Y^{2}=12 X \) c. \( Y=\sqrt{ } 4 X \)

The graph to the right shows a region of feasible solutions. Use this region to find maximum and minimum values of the given objective functions, and the locations of these values on the graph. (a) \( z=4 x+3 y \) (b) \( z=1.75 x+1.25 y \)
