Assume that no function has a period greater than 2π.A.B.C.D.When a guitar string is plucked, it is displaced from a fixed point in the middle of the string and vibrates back and forth, producing a musical tone. The exact tone depends on the frequency, or number cycles per second, that the string vibrates. To produce an G, the frequency is 390 cycles per second, or 390 hertz. What is the period of this function?6/5 seconds0.02 seconds0.0025 seconds11.3 secondsIn a certain area of forested land, the population of rabbits R increases and decreases periodically throughout the year.
