Think of another real world situation that might invoke horizontal and vertical lines write a description of the situation and draw the graph of a coordinated plane with two horizontal and two vertical lines to represent your situation draw the lines so that two of them pass through positive values and the other two pass through negative values on the coordinate plane then write equations for all four of the lines on the graph

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?
