How do you solve this using special right triangle this is geometry

What is the location of point g, which partitions the directed line segment from d to f into a 5: 4 ratio? –1 0 2 3

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?

Solve the following pair of equations for x and y: ax/b_ by /a= a +b; ax - by = 2ab
