Take m = 50 , n=12. using matlab's linspace define t to be the m-vector corresponding to linearly spaced grid points from 0 to 1. using mathlab vander and fliplr define a to be the m*n matrix associated with least squares fitting on this grid by a polynomial of defree n-1

Achemist has 200 ml of a 10% sucrose solution. she adds x ml of a 40% sucrose solution. the percent concentration, y, of the final mixture is given by the rational function: the chemist needs the concentration of the final mixture to be 30%. how many milliliters of the 40% solution should she add to the 10% solution to get this concentration?

What are the solutions of the system? solve by graphing. y = -x^2 -6x - 7 y = 2
