Answer:
1. Modified formulae for calculating tree height.
.
2. C++ program to calculate tree height.
#include<iostream>
#include<math.h>
using namespace std;
int
main ()
{
double treeHeight, shadowLenghth, angleElevation;
cout << "Please enter angle of elevation and shadow length" << endl;
cin >> angleElevation;
cin >> shadowLenghth;
//Modified formulae to calculate tree height.
treeHeight = tan (angleElevation) * shadowLenghth;
cout << "Height of tree is:" << treeHeight;
}
Output:
Please enter angle of elevation and shadow length
45
12
Height of tree is:19.4373
Explanation:
Since no programming language is mentioned, so solution is provided using C++.
In the above C++ program, first angle of elevation and length of shadow provided by user will be stored in variables angleElevation and shadowLength.
Then using the modified formalue height of tree will be calculated and stored in variable treeHeight. Final result is displayed to user.
Answer:
The correct answer is d.In an E-R model, the three types of maximum cardinality are 1:1, 1:N, and N:M.
Explanation:
An entity relationship diagram is a diagram that illustrates how "entities" relate to each other. ER diagrams of a system are often used to design or refine relational databases in the areas of software engineering, business information systems, education, and research. Also known as the ERD model or ER model, they use a set of defining symbols such as rectangles, rhombuses, ovals, and links to express the cohesion of entities, relationships, and their properties. They are a reflection of the grammatical structure and the use of entities as nouns and relationships as verbs.
Answer:
public class Car {
private int yearModel;
private String make;
private int speed;
public Car(){
yearModel = 2000;
make = "Nissan";
speed = 4;
}
public Car(int yearModel, String make, int speed) {
this.yearModel = yearModel;
this.make = make;
this.speed =speed;
}
public void setYearModel(int yearModel){
this.yearModel = yearModel;
}
public void setMake(String make){
this.make = make;
}
public void setSpeed(int speed){
this.speed = speed;
}
public int getYearModel(){ return yearModel; }
public String getMake(){ return make; }
public int getSpeed(){ return speed; }
public String toString(){
return "Car's year model: " + getYearModel() + ", make: " + getMake() + ", speed: " + getSpeed();
}
}
Explanation:
<em>Variables</em> are declared.
<em>No-arg constructor</em> is created with default values.
<em>A constructor with parameters</em> is created.
The required <em>set methods</em> and <em>get methods</em> are created.
<em>toString</em> method is created to return car's specifications.
