Aspinner is divided into eight equal-sized sections, numbered from 1 to 8, inclusive.

what is true about spinning the spinner one time? check all that apply.

~ s = {1, 2, 3, 4, 5, 6, 7, 8}

~if a is a subset of s, a could be {1, 2, 3}.

~if a is a subset of s, a could be {7, 8, 9}.

~if a subset a represents spinning a number less than 4, its sample space is a = {1, 2, 3, 4}.

~ if a subset a represents the complement of spinning an odd number, its sample space is a = {2, 4, 6, 8}.

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?
