Resolva cada equação seguinte e marque a opção correta* x = - 7/2 = - 3,5 x = 1 k = 133 x = - 2 x = 7 x = 2 x = 10 x = 9/2 = 4,5

-2x + 9 = 0

x/ 2 + 3 = 8

x - 8 = - 3x

3 + 2x - 4 = 13

k/7 = 19

7x + 8 = 3x

2x + 7 =0

- 3x + 1 = -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?
