5. you have a gift card for your favorite clothing store for the amount of $60. you have found a
shirt you want to buy that costs $15. if you don't want to spend more than the amount of the
gift card, which of the following inequalities could be used to determine the amount you have
left to spend?
x+15 > 60
cx- 1560
cx-15560
x + 15 < 60

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?
