Answer:
The MATLAB code will be:
close all;
clc;
clear all;
a = [20, 1, -2; 3, 20, -1; 2,-3, 20];
b = [17; -18; 25];
tol = 1e-6;
[M,N] = size(a);
if M~=N
error('A is not a square Matrix');
end
x = [0,0,0];
xx(1,:) = x;
n = 100;
error = 0.00001;
for k = 2:n
for i = 1:N
s = 0;
for j = 1:N
if j ~= i
s = s + a(i,j) * x(j);
end
end
x(i) = (1/a(i,i)*(b(i) - s));
end
xx(k,:) = x;kk = k;
Error = abs(max(xx(kk,:)- xx(k-1,:)))
if Error<error
break;
end
end
fprintf ('The roots of equation are: ')
x
fprintf ('The number of iterations are: ')
k
fprintf ('The error is: ')
Error

Answer:
Their company address
When their last tax period started
How often they have to file a tax return
When they started collecting sales tax for the agency
Explanation:
For setup the sales tax information in Quickbooks online for a client who only does business in their home state, we need these information which are given below:

2. Last Tax Time period started
3. How frequently they filed the tax return
3. when they begin to received sales tax
Therefore all the other options are not valid. Hence, ignored it
Answer:
Explanation:
Given
Temperature of solid 
Einstein Temperature 
Heat Capacity in the Einstein model is given by
