Determine the equation of the following polynomials, using the given information. Write each polynomial in factored form and also in standard form. Don’t forget to solve for a!

A cubic whose zeros are at x = 2, x = -3 and x = 1 and the y-intercept is -12.

(if f(x)=4x^2 and g(x)=x+1, find (f o g)(x)

The angle of a triangle are given as 6x,(x-3), and (3x+7). find x then find the measures of the angles

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?
