Sully and genesis purchase two matinee movie tickets. a matinee ticket costs $6.50, a drink costs $5.50, and a bag of popcorn costs $6.00. define each variable and write an algebraic expression to describe how much they spend on the number of drinks and bags of popcorn they buy. identify the parts of the expression by underlining the coefficient(s) and circling the constant(s), and drawing abox around the variable(s)

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?
