POSSIBLE POINTS Mr. Goldstein is driving to Houston. The equation y=-45x + 270 represents the numbers of miles that he still has to travel after driving for x hours. What is the slope of the line and what does it represent in this situation? O 270 and it represents the driving miles per hour O 270 and it represents how many miles he had to drive O 45 and it represents the number of driving miles per hour -45 and it represents the number of miles he had to drive​

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?
