Thomas is transferring files from his computer into his flash drive. The size of the files on the drive D (megabytes) as a function of time t (sec) is modeled with the following function: d(t) = 6t + 38. 11. the shape of the graph
13. the domain and range

Find the value of tan theta if sin theta = 12/13 and theta is in quadrant 2

What are the solutions of the system? solve by graphing. y = -x^2 - 3x + 2 y = -2x + 2

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?
