True.
System can be used to model linear and nonlinear DEs.
A linear differential equation is a differential equation that is defined by a linear polynomial in the unknown function and its derivatives, that is an equation of the form
y'+p(x)y = q(x).
A nonlinear system is a system in which the change of the output is not proportional to the change of the input
The Bisection and False-position Method can be used to solve linear systems of equations Ax = b True False fzero() will converge to the root for any initial guess. True False The number of iterations required to find the root via the Bisection and False-position methods increases as the tolerance value decreases. True False

(e) (4) The Reptation model can be used to predict the linear viscoelastic behavior (G', G" versus frequency) of branched polymers
As a general rule, advanced planning systems rely on nonlinear programming. simulation. linear approximations of nonlinear functions. game theory.

Standard costing can be used for both job order and process costing systems. True False Due to the nature of the procedures involved, service companies do not use standard costing. True False Due to the nature of the procedures involved, service companies do not use standard costing. True False Under standard costing, the inventory account balance may not actually reflect the true costs incurred to acquire the inventory. True False
A regression model that is linear in the unknown parameters is a linear regression model. A) True B) False The test for significance of regression in multiple regression involves testing the hypotheses Ho: B1=B2=B3=0 versus H1: B1≠B2≠B3≠0. A) True B) False The ANOVA is used to test for significance of regression in multiple regression. A) True B) False
1. True or False: Non-linear quality constraints can never be rewritten as linear constraints. 2. True or False: Every optimization problem with linear constraints is a linear programming problem.
FEA
1. Answer True or False below. (2 points each) When performing a nonlinear FE analysis, pressure is considered a “follower force.” Once an element aspect ratio exceeds 1, the larger the aspect ratio, the better the element performs. Eigenvalue buckling provides a good estimate of the Euler critical buckling load. It is important to include the Bauschinger effect in your FE model when simulating problems that experience large strain. Buckling can be considered as the inverse of stress stiffening....
hello can someone help me answer this please
Exercise 2.5. Consider finding a zero of function F : D as the sum of a linear and nonlinear part: Rn → Rn that can be written F(x) BG(x) where B is a nonsingular matrix and G DCRR" is a general nonlinear function. At a point ak consider a general linear model Mk(x)Ak(x -), where the quantities ak E R" and Ak E Rn*n are to be determined. Define the linear model...
2. Consider the nonlinear autonomous system of DEs: dx dt dy dt (a) Find all critical points of this system. (Make sure that you have found all of them.) (b) Find the linearization (a linear system) at each critical point. Calculate the eigen- values of the contant coefficient matrix, classify the corresponding critical point, and state its stability.
