Find the displacement function if the acceleration function is a=2t+5. Assume a zero initial condition of displacement and v=8 when t=1.

Integrating the acceleration function gives the velocity function v, as below: v = t 2 +5t +C 1 , where C 1 is a constant. Integrating the velocity function gives the displacement function x, as below: x = t...

Do y=3x^2+5x+12 and y=3x-8 intercept with each other? If yes, at which point(s)?

This is like solving 2 simultaneous equations. Both equations are in a form of y=ax^2+bx+c. Equate both equations together and you got: 3x 2 +5x+12 = 3x-8 Put both polynomials at one side and you got: 3x 2 +...
