1. Solve the following polynomial inequality: 5 2 3 x + x 2 x + 2 2 2. Solve the following using Quadratic Formula: 0.5 x x=2 3. The number of kidney transplants from 1996 to 2005 can be expressed by the quadratic equation of y = 3.6x 2 + 578x + 13,538, where x = 0 represents the year 2000. Assume this trend continues and predict the year when 23,018 kidney transplants are performed. 4. I have a friend with a furniture company that has determined when 'x' hundred wooden chairs are built, the average cost (C) per chair (x) is given by the following equation: C(x) = 0.1x2 - 0.7x + 1.625 C(x) is in hundreds of dollars. How many chairs should be built in order to minimize the average cost per chair? 5. Solve the following equation to show a complex (i) solution (the solution must be complex to be correct!): (x + 2)2 = -25
