If statistics professor bought a new car for 35,000 for the next five years she use several automotive webpages to estimate the value of her car she then found the least squares regression line for the data to be Y equals 35035.71-4142.86 X the correlation coefficient was -0.99 would it be accurate to use this equation to predict the value of the car after 10 years?

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?
