use the picture to you solve part a and b***
part b
use matrix manipulation to solve for a, b, and c. set up a matrix equation for ax = b based on the system of equations you derived in part b where x is a matrix of the variables a, b, and c. then, use gauss-jordan elimination to find the inverse of a. finally, use your results to write the equation of the parabola. show your work and final equation in the space provided.
part c
now that you have determined the equation of the parabola, assume that x represents the number of seconds that have passed since the ball was thrown and determine approximately how long it will take for the ball to hit the ground.
