The initial tableau of a linear programming problem is given. Use the simplex method to solve the problem. x₁ X2 51 $2 53 Z 1 6 1 0 0 0 15 4 1 0 1 0 0 20 1 1 0 0 1 0 4 -4 -3 0 0 0 1 0 The maximum is when x₁ = ☐ x2 = ☐. S₁ = ☐, 52 = ☐, and S3 = ☐ (Type integers or simplified fractions.) 51 example Get more help - Clear all Check answer

Find the minimum of the function f(x) = x³ – 5x³ – 13x + 4 using quadratic interpolation. Use x0 = 0, x1 = 2, x2 = 4 as an initial quess. Tip: Make table with x0,x1,x2,x3, f (x0),ƒ (x1), f(x2),f(x3). Remove the worst quess from these and arrange 20,x1,x2 values in ascending order then conducts iteration ie. calculate new x3 and f (x3) iterate again until you get two same į values with for example five decimal points. Insert the numerical value of minium value for f(x) here f_x = -30.176 Verify your answer here fi = -30.176

How can you tell from the vertex form y = a (x-h²) + k whether a quadratic function has two real zeros? Choose the correct answer below. O A. The quadratic function has two real zeros if a > 0, k>0 and h#0. OB. The quadratic function has two real zeros if a>0 and k>0 or a 0 and k0.
