For a short time after a wave is created by wind, the height of the wave can be modeled using y = a sin 2πt/t , where a is the amplitude and t is the period of the wave in seconds.

part 1: write an equation for the given function given the amplitude, period, phase shift, and vertical shift.
amplitude = 4 , period = 4π , phase shift = -4/3 π , vertical shift = -2

part 2: write an equation for the given function given the period, phase shift, and vertical shift.
cotangent function, period = π , phase shift = -1/3 π , vertical shift = 2

Asystem of equation is shown below 6x - 2y equals 3 . and 5x + 3y equals 4. would you solve by substitution or elimination? and why

Demonstrate the proof of your new polynomial identity through an algebraic proof and a numerical proof in an engaging way! make it so the whole world wants to purchase your polynomial identity and can't imagine living without it! you must: label and display your new polynomial identity prove that it is true through an algebraic proof, identifying each step demonstrate that your polynomial identity works on numerical relationships create your own using the columns below. see what happens when different binomials or trinomials are combined. square one factor from column a and add it to one factor from column b to develop your own identity. column a column b (x − y) (x2 + 2xy + y2) (x + y) (x2 − 2xy + y2) (y + x) (ax + b) (y − x) (cy + d)
