Question 2

  1. 1. Question 2 Tides
  2. 2. During the day, the Earth rotates 180 degrees in 12 hours. The moon, meanwhile, rotates 6 degrees around the Earth in 12 hours. This results in a high tide of 2 feet above the mean sea level, at approximately every 12 hours and 30 minutes. If the depth of the water is at its max at 12:00 a.m. on January 1 st : a.) Graph this function. b.) Write two equations representing this graph; one sine, one cosine. c.) At what time to the nearest minute of the day on January 1 st will the level of water reach 1.25 feet above sea level for the first time?
