jack bought a tree to plant in his front yard. the tree grows at an approximate rate of 9 inches per year. after 4 years, the tree is 5 feet tall. write an equation in slope-intercept form to find the height (in feet) of the tree, y, after x years. then, find the number of years it will take the tree to reach 20 feet

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?
