find the volume of the solid e whose boundaries are given in rectangular coordinates E is located insaide the cylinder x^2 y^2

What are the solutions of the system? solve by graphing. y = x^2 + 3x + 2 y = 2x + 2

Can you me find the missing length. i attached an image.

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?
