ANSWER

EXPLANATION
The frequency of a wave function refers to the number of times the graph repeats its cycle within the interval [0,2π]
We can observe explicitly from the graph that the frequency is half.
The period of the given function is 4π


Hence the frequency is half.
Answer: 20 feet per second
Step-by-step explanation:
Do 80 divided by 4
The answer would be 8746 ft :)
Each result is equally likely to occur!!
