the earth rotates from to
about its axis causing day and night on earth. due to this
rotation, the sun in adelaide while perth is still in
the earth rotates in one day. there are different time zones around
the earth. these are generally based on the lines of longitude, known as
measurements of time begin at london with zero degrees longitude. the
international date line is 180 degrees east/west of the prime meridian. each new day begins in
the time zone to the the international date line and works its way around the
world over the next 24 hours.

In one day there are too high tides into low tides and equally spaced intervals the high tide is observed to be 6 feet above the average sea level after six hours passed a low tide occurs at 6 feet below the average sea level in this task you will model this occurrence using a trigonometric function by using x as a measurement of time assume the first high tide occurs at x=0. a. what are the independent and dependent variables? b. determine these key features of the function that models the tide: 1.amplitude 2.period 3.frequency 4.midline 5.vertical shift 6.phase shift c. create a trigonometric function that models the ocean tide for a period of 12 hours. d.what is the height of the tide after 93 hours?
