E the empirical rule to estimate the number of farms whose land and building values per acre are between ​$900 and ​$1500.

Graph the system: f(x)= 3/x-2; f(x)= 1/2x + 2

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?

Plz ( true - false) all triangles have interior angles whose measure sum to 90.
