The solution is B. π/12+nπ

proof
sinx cosx = 1/4 is equivalent to 2 sinx cosx = 1/2 or sin2x =1/2
so 2x = arcsin(1/2) = π/6 + 2nπ, so x = π/12+nπ

What is f(5) if f(1) = 3.2 and f(x + 1) =5/2 (f(x))?

dimulka [17.4K]

F(x + 1) = (5/2)*f(x)

f(x + 1) = 2.5*f(x), f(1) = 3.2

f(2) = 2.5f(1) = 2.5*3.2 = 8

f(3) = 2.5f(2) = 2.5*8 = 20

f(4) = 2.5f(3) = 2.5*20 = 50

f(5) = 2.5f(4) = 2.5*50 = 125
