a right circular cone has an altitude of 12 ft and a base radius of 6 ft. a second cone is inscribed in the first, with its vertex at the center of the base of the first cone and its base parallel to the base of the first cone. find the dimensions of the cone of maximum volume that can be so inscribed

What is the missing constant term in the perfect square that starts with x^2 -20x

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?
