The goals against average (a) for a professional hockey goalie is determined using the formula a = 60 a equals 60 left-parenthesis startfraction g over t endfraction right-parenthesis.. in the formula, g represents the number of goals scored against the goalie and t represents the time played, in minutes. which is an equivalent equation solved for g? startfraction a t over 60 endfraction equals g.= g startfraction a over 60 t endfraction equals g. = g startfraction 60 a over t endfraction equals g. = g 60at = g

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?
