The global positioning system (GPS) is a space-based radio-positioning and time-transfer system. GPS satellites transmit signals to proper equipment on the ground. These signals provide accurate position, velocity, and time (PVT) information to an unlimited number of users on ground, sea, air, and space.
Answer:
metrics
Explanation:
Given that Metrics is Metrics is an accepted technique of measuring quantities of elements or commodities.
It is used in all facets of human activities particularly in value measurement such as production operation, financial assessment, comparison purposes, etc.
Hence, In addition to benchmark testing, performance measurements, called METRICS, can monitor the number of transactions processed in a given period, the number of records accessed, and the volume of online data.
Answer:
public static void quad(double a, double b, double c) {
double D = (Math.pow(b, 2)) - (4 * a * c);
if (D<0){
System.out.println("no real solutions");
}
}
Explanation:
The code snippet above implements the function in Java programming language
As required by the question, the line double D = (Math.pow(b, 2)) - (4 * a * c); evaluates b squared" - 4ac and assignes the value to the variable D
An if statement is used to test if D is less than 0, if this is true the message no real solutions is printed
Answer:
A)
This is an example of tight coupling since the class Working has to have an idea of how Person is implemented to complete its own implementation.
B)
Any change in the Person class would require a change in the working class too.
C)
CODE
class Person {
int personID, age;
String fName, middleName, lastName;
public int getAge() {
return age;
}
}
// end of Person class
class Working extends Person {
boolean isUnderEighteen() {
if (super.getAge() <18) {
System.out.println("The person is under age and cannot work");
return true;
}
else {
System.out.println("The person can legitimately work");
return false;
}
}
}
