The number of motorcycle helmets produced in a factory each day is a function of the number of hours (h) the assembly line is in operation that day and is given by n =
P(t) =
75t-2t^2. The cost C of producing the helmets is a function of C(n) = 7n + 1000

Marcus needs to rewrite f(x) = x2 + 6x + 4 in vertex form.

Factor k2 - 17k + 16. a.(k - 2)(k - 8) b.(k - 1)(k + 16) c.(k - 1)(k - 16)

Suppose that 3% of all athletes are using the endurance-enhancing hormone epo (you should be able to simply compute the percentage of all athletes that are not using epo). for our purposes, a “positive” test result is one that indicates presence of epo in an athlete’s bloodstream. the probability of a positive result, given the presence of epo is .99. the probability of a negative result, when epo is not present, is .90. what is the probability that a randomly selected athlete tests positive for epo? 0.0297
