Answer:
System of linear equations is solved below and explained in detail.
Explanation:
Part a:
M = [1 3 5 2; 2 -4 7 -3; 0 -4 -7 3; 5 -3 2 1];
c = [7; -3; -1; 0];
Part b:
The statement used for the solution of system of linear equation will be:
X = linsolve(M,c)
where X will give the values of x1, x2, x3, x4 respectively.
Part c:
The system is solved in matlab using above equation and the results are attached in a file.
The values for X are:
x1 = -2/7
x2 = 3/7
x3 = 4/7
x4 = 11/7
Answer:
<em>DBMS Performance
</em>
Explanation:
Database tuning <em>defines a range of activities that are used to maximize and homogenize a database's output.</em>
This typically coincides with query tuning, but applies to database file layout, DBMS software selection, and database environment setup (operating system, CPU).
Database tuning helps to optimize the use of machine resources in order to carry out work as efficiently and quickly as possible.
Many systems are built to handle their use of system resources, but there is still plenty of space for enhancing their performance by tailoring their server and DBMS settings and configuration.
English:
Recycling, in general, is good, it saves space in landfills and prevents pollution. Because some of the materials used to make the electronic piece are made with toxic ingredients its better to recycle them instead of having them end up in our oceans. Also, some pieces of electronics contain valuable metals like gold and copper. These Metals can be reused to make new better electronics with having to use the energy and money to produce new materials
Español:
El reciclaje, en general, es bueno, ahorra espacio en los vertederos y evita la contaminación. Debido a que algunos de los materiales utilizados para fabricar la pieza electrónica están hechos con ingredientes tóxicos, es mejor reciclarlos en lugar de que terminen en nuestros océanos. Además, algunos componentes electrónicos contienen metales valiosos como el oro y el cobre. Estos metales se pueden reutilizar para fabricar nuevos y mejores productos electrónicos con la necesidad de utilizar la energía y el dinero para producir nuevos materiales.
Answer:
a
Explanation:
analog signal sent through tiny glass strands
public class Circle {
// the private data members
private double radius;
private double area;
private double diameter;
public void setRadius(double r)
{
radius = r;
}
public double getRadius()
{
return radius;
}
public double computeDiameter()
{
return radius * 2;
}
public double computeArea()
{
return ((radius * radius) * 3.14);
}
}
