Write the product in the form a + bi,
(3 + 5i)(3 – 5i)

The table represents a function f(x). what is f(3)? a.-9 b.-1 c.1 d.9

If tan2a=cot(a+60), find the value of a, where 2a is an acute angle

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
