Answer:
see explaination
Explanation:
function [] =
inverse(A,B)
da = det(A);
disp("The det of A is");
disp(da);
inva = inv(A);
disp("The inverse of A is");
disp(inva);
x = inva*B;
disp("The value of X is");
disp(x);
rk = rank(A);
disp("The rank of X is");
disp(rk);
Di = eig(A);
disp("The eigen values of A is");
disp(Di);
[V,Di] = eig(A);
disp("The eigen vectors of A are (Each column represents one column vector)");
disp(V);
end
A = [1,2;4,5];
B = [1,2;4,5];
inverse(A,B);
%ab = [num2str(t)," ",num2str(dx)," ",num2str(dy)];
%disp(ab);

Answer:
There are two customers in the PostalCode.
SQL statement for select all the fields and the rows from the Customers table where PostalCode is 44000.
SELECT * FROM Customers WHERE PostalCode = "44000";
Explanation:
The SELECT statement retrieve zero or more than one row from 1 or more than one the database tables or the database views.
In most of the applications, the SELECT query is most commonly used for DQL(Data Query Language) command.
SQL is the declarative programming language and the SELECT statement specifies the result set, but they do not specifies how to calculate it.

The answer to this question can be described as follows:
Explanation:
Relational data model:
The use of data tables to organize sets of entities into relationships requires a relational data model. this model work on the assumption, which is a primary key or code, that is included in each table configuration. The symbol for "relational" data links and information is used by other tables.
Model Design:
This model is used for database management, it consists of structure and language consistency. It is design in 1969.
Importance of data model:
This provides a common standard for processing the potentially sound data in machines, that was usable on almost any one device.
Big Data:
It moves to locate new and innovative ways to handle large volumes of authentication tokens and to gather business insights when offering high efficiency and usability at an affordable cost at the same time.
