What is the period of the graphed function?
a. π
b. 0.75
c. 2 π
d. π/2
e. -0.75

A. π

Step-by-step explanation:

this is a graph of  a cosine function and and the interval during which it completes one cycle starting from the origin, according to the graph is  π

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3

a is the right answer
