- I need help with a MATLAB code. I need to find two values of n, one that is positive and one that is negative, that will give all negative real roots. Can you help me find them? function [r] = find_roots(n) % Define constants I = 400; J = 150; x = (J/I) - 1; y = n - 1; Q = y + x*(y-1); % Define the coefficients of the quadratic equation coefficients = [1, 0, (3*x+Q^2+1), 0, (3*x*Q+Q^2)]; % Find the roots r = roots(coefficients); endarrow_forwardHandwriting solutions mustarrow_forward2. There were 42 mangoes in each crate. 12 such crates of mangoes were delivered to a factory. 4 mangoes were rotten and had to be thrown away. The remaining mangoes were packed into boxes of 10 mangoes each. Write a numerical expression in MATLAB syntax to represent this situation and then find how many boxes of mangoes were there?

- Determine the units of the variable x in each of the following equations, and specify which rule you used to determine this. Do not solve for the numeric value of x. Show your work beneath the question, or on a separate sheet of paper. Example: 315 feet = (32)x² Rule #1: Both sides of the equal sign must have the same units. Rule #2: Values that are added or subtracted must have the same units. Rule #13: Argument of a trig function must be an angle. Rule #14: Argument of an inverse trig function must have no units. Rule #5: Exponents must have no units. x has units of seconds because of Rule # 1arrow_forwardSolve the branch carrow_forwardc,b and a values in this question is: c=2 b=0 a=7arrow_forward
- 4 of 11 Plane-Stress Transformation Learning Goal: The state of in-plane stress at a point on an element of material is shown. Let |ox| = 320 MPa, |oy| = 120 MPa, and |Txy| = 75.0 MPa. Use this information to represent the state of stress of the same point that is rotated through an angle of 0 = 25.0°. b Txy σx Part A - Normal and shear stress on element sectioned at plane a-a Using the element sectioned at plane a-a and the rotated coordinate system shown, determine the normal and shear stresses, σ and Ta'y', respectively, acting on plane a-a. 90-0 -90-8 X Express your answers in MPa to three significant figures separated by a comma. 0arrow_forwardFor Questions 3 and 4: A cup of water was heated to a temperature of 90°. It was placed in a refrigerator that had a temperature of 11°C. The water cooled to a temperature of 17°C in 30 minutes. Let the following variables represent the relevant quantities. L = Temperature of the liquid S= Temperature of the surroundings t = Time B = Initial temperature of the liquid (Temperature at t = 0 k = Cooling constant 3. Using the Equation Solver, find the value of k in the equation L = (B - S)e -kt + S.
