On a sunny summer day, you are taking the scenic boat ride from stein am rhein, switzerland, to schaffhausen, down the rhein river. this nonstop trip takes 40 minutes, but the return trip to stein, upstream, will take a full hour. back in stein, you decide to stay on the boat and continue on to constance, germany, now traveling on the still waters of lake constance. how long will this nonstop trip from stein to constance take? you may assume that the boat is traveling at a constant speed relative to the water throughout and that the rhein river flows at a constant speed between stein and schaffhausen. the traveling distance from stein to schaffhausen is the same as from stein to constance.

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?

I’m really confused and need your assist me with this question i’ve never been taught

The police chief wants to know if the city’s african americans feel that the police are doing a good job. identify the management problem (i.e dependent variable) and identify the independent variable.
