Find at least three examples of the use of percents in real-world settings. Use newspapers, magazines, video clips, Internet articles, or other resources. Use one of your examples to create a real-world problem for other students to solve. A. Post the pictures, articles, recordings, or links of your three examples to the discussion board as well as the problem you created from one of your examples. Be sure to give a short description of what you found.

B. Read another student’s post and solve their example problem.

C. Review for accuracy and respond to replies to your post.

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?
