Using a directrix of y = ? 2 and a focus of (2, 6), what quadratic function is created? (5 points) f(x) = ? one eighth (x ? 2)2 ? 2 f(x) = one sixteenth (x ? 2)2 + 2 f(x) = one eighth (x ? 2)2 ? 2 f(x) = ? one sixteenth (x + 2)2 ? 2

If the ratio of sum of the first m and n terms of an ap is m2 : n2 , show that the ratio of its mth and nth terms is (2m − 1) : (2n − 1).

The probability that a student graduating from suburban state university has student loans to pay off after graduation is .60. if two students are randomly selected from this university, what is the probability that neither of them has student loans to pay off after graduation?

Someone answer this asap for the first five terms of a sequence are shown. 5, 11, 23, 47, 95, . . which recursive function defines the nth term in the sequence for n > 1? a. f(n) = f(n - 1) + 6 b) f(n) = f(n - 1) + 48 c) f(n) = 3 • f(n - 1) + 1 d) f(n) = 3 • f(n - 1) - 4
