This is the second page to the previous questions all these problems need to to be executed in matlab.

Use solve to solve the following system of equations: xy - 2x = 4 y - 4x = 7 Assign to p11. The following problem spans several questions. Begin by assigning p12 to squareroot 50. Calculate s48 + p12. Assign to p13. Calculate squareroot p13/3. Assign to p14. Calculate sin(2p14). All angles should be treated as radians. Assign to p15. Use solve to solve the equation 8 x^2 + bx + 9 = 0 for b. Assign to p16. Use solve to solve the equation 3ab - b - 2/b = 2a for b. Assign to p17. The following problem spans several questions. First define the function f(x) = 2x^2 + 8x + 7 symbolically. Assign to f (x). Calculate f(6) f(6) - f(6 + f(9)) + f(f(2)f(3)) Assign to p19. Use simplify to simplify f(1 - 4x^2 + 8x^3 - 7x^4). Assign to p20. Use solve to solve f(x) = 7. Assign to p21. Use solve to solve 4f(4x) = 5 + f(x + 4). Assign to p22. The following problem spans several questions. First define the function g(x) = symbolically. Assign to g(x). Define the function h(x) = 6x + 3 symbolically. Assign to h(x). Use solve to solve 4g(x) = h(5x). Assign to p25. Use solve to solve g(h (x)) = h(g(x)). Assign to p26. Use vpasolve to approximate all of the solutions to 5x^5 + 9x^4 + 3x^3 + 6x^2 +3x + 7 = 0. Assign to p27. Use vpasolve to approximate an x-intercept of the y = cx/7 + cos (x/7 - 4) + e^(x/7 - 4) - 4 near 21. Assign to p28. Use vpasolve to approximate the largest x-intercept of the function y = sin x + 0.4 (1.2^x). Use a nearby sensible integer value of your choice. Find this nearby sensible integer however you wish, how you find it is not part of the assignment. Assign to p29
