A group of scientists wants to determine how members of a community view climate change. Which of the following would best accomplish this goal? creating a model of the effects of climate change on an ecosystem

performing a laboratory experiment to replicate the effects of climate change
conducting fieldwork to analyze the different gases that contribute to climate change

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?
