3.) Eric is planning a road trip using a map in the standard (x, y) coordinate plane where1 coordinate unit represents 1 mile. The starting point of his road is located at (2,6) and the
ending point is located at (32, -21). What is the straight-line distance, in miles between the
starting and ending points of his trip?

What is the length of the segment joining the points at (4,5) and (6,-2) round to the nearest tenth if necessary

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?
