PLEASE JUST DO PART B AND C. PLEASE PLEASE JUST GIVE ME THE CODE THAT I NEED TO RUN ON MATLAB. PLEASE JUST THE CODE. I WILL REALLY APPRECIATE IT. THANK YOU!

5.12 Water is flowing in a trapezoidal channel at a rate of Q = 20 m/s. The critical depth y for such a channel must satisfy the equation 0= 1 843 100 lb/ft 100 lb wher cons sent vati rela 3- 3- 4 -2- FIGURE P5.11 where g = 9.81 m/s, A= the cross-sectional area (m), and B = the width of the channel at the surface (m). For this case, the width and the cross-sectional area can be related to depth y by B=3+y and 4,= 3y + 4 Solve for the critical depth using (a) the graphical method, (D) bisection, and (c) false position. For (b) and (c) use mal guesses of x, = 0.5 and x. = 2.5, and iterate until the approximate error falls below 1% or the number of iterations exceeds 10. Discuss your results. . Linetics of th
