Which statement best reflects the solution(s) of the equation? √3x+1 −x+3=0 (note it's the square root of 3x+1) a. there is only one solution: x = 8. the solution x = 1 is an extraneous solution. b. there is only one solution: x = 8. the solution x = 0 is an extraneous solution. c. there is only one solution: x = 1. the solution x = 8 is an extraneous solution. d. there are two solutions: x = 1 and x = 8.

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?
