If the cos 42° = one half, then the sin 48° =

two thirds, because the angles are complementary
2 over 1, because the angles are supplementary
one half, because the angles are complementary
1, because the angles are complementary

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
