Which of the following functions has a period of 4pi? A.)y=sin2 x

B.)y=sin 1/4x

C.)y=sin4 x

D.)sin 1/2 x

answer: y = -12x + 108

step-by-step explanation: do (y = m x+b) formula.

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
