a. Show the output of the following program: 1: public class Test { 2: public static void main ( String [] args ) { 3: A a = new

A( 3 ); 4: } 5: } 6: 7: class A extends B { 8: public A ( int t ) { 9: System.out.println( "A's constructor is invoked" ); 10: } 11: } 12: 13: class B { 14: public B () { 15: System.out.println( "B's constructor is invoked" ); 16: } 17: } b. Is the no-arg constructor of Object invoked when new A(3) is invoked? 6. Indicate true or false for the follow statements: a. You can always successfully cast an instance of a subclass to a superclass. b. You can always successfully cast an instance of a superclass to a subclass. 7. What's wrong with the following code? 1: public class Test { 2: public static void main ( String [] args ) { 3: Object fruit = new Fruit(); 4: Object apple = (Apple) fruit; 5: } 6: } 7: 8: class Apple extends Fruit { 9: } 10: 11: class Fruit { 12: } 8. When overriding the equals method, a common mistake is mistyping its signature in the subclass. For example, the equals method is incorrectly written as equals (Circle circle) as shown in (a) below. It should be written as equals(Object circle), as shown in (b) below. Show the output of running class Test using the Circle class first from (a), and then from (b). Explain the output. 1: public class Test { 2: public static void main ( String [] args ) { 3: Object circle1 = new Circle(); 4: Object circle2 = new Circle(); 5: System.out.println( circle1.equals( circle2 ) );

Friedman (1999) argues that "we are wrong to base health promotion in all societies on a Western framework for human development
Dovator [93]

Answers with Explanation:

A. Give at least two reasons why he believes this.

Friedman believes that health promotion based on Western framework for human development<em> unfairly criticizes the other cultures in the society.</em> Western framework values intellectual and economic achievements alone, which then <em>results to putting a great expense on the other essential human qualities.</em>

B. What crisis does he believe is happening in the most economically developed countries?

The crisis that is happening in the most economically developed country is the <em>devaluing of the other aspects which other human beings value in terms of individuality or families.</em>

C. What does he recommend to improve the programming for adolescent health?

He recommends that if changes were to be implemented for adolescent's health, <u>these have to be properly assessed regarding their effect on the adolescent's development,</u> including his/her family and other social relationships. Next is to check whether<u> it doesn't conflict with the adolescent's culture in the community that he belongs</u>. If it does, then it is essential to change it or find <em>another way which fosters</em><em> </em><em>the same goal.</em>

Business customers pay $0.006 per gallon for the first 8000 gallons. If the usage is more than 8000 gallons, the rate will be $0
trasher [3.6K]

Answer:

#include <bits/stdc++.h>

using namespace std;

int main()

{

   // variables

   char cust_t;

   int no_gallon;

   double cost=0;

   cout<<"Enter the type of customer(B for business or R for residential):";

   // read the type of customer

   cin>>cust_t;

   // if type is business

   if(cust_t=='b'||cust_t=='B')

   {

       cout<<"please enter the number of gallons:";

       // read the number of gallons

       cin>>no_gallon;

       // if number of gallons are less or equal to 8000

       if(no_gallon<=8000)

       {

           // calculate cost

           cost=no_gallon*0.006;

           cout<<"total cost is: $"<<cost<<endl;

       }

       else

       {

           // if number of gallons is greater than 8000

           // calculate cost

           cost=(8000*0.006)+((no_gallon-8000)*0.008);

           cout<<"total cost is: $"<<cost<<endl;

           

       }

       

   }

   

   // if customer type is residential

   else if(cust_t=='r'||cust_t=='R')

        {

           

       cout<<"please enter the number of gallons:";

       // read the number of gallons

       cin>>no_gallon;

       // if number of gallons are less or equal to 8000

       if(no_gallon<=8000)

       {

           // calculate cost

           cost=no_gallon*0.007;

           cout<<"total cost is: $"<<cost<<endl;

       }

       else

       {// if number of gallons is greater than 8000

       // calculate cost

           cost=(8000*0.005)+((no_gallon-8000)*0.007);

           cout<<"total cost is: $"<<cost<<endl;      

       }        

   }

return 0;

}

Explanation:

Ask user to enter the type of customer and assign it to variable "cust_t". If the customer type is business then read the number of gallons from user and assign it to variable "no_gallon". Then calculate cost of gallons, if  gallons are less or equal to 800 then multiply it with 0.006.And if gallons are greater than 8000, cost for  first 8000 will be multiply by 0.006 and  for rest gallons multiply with 0.008.Similarly if customer type is residential then for first 8000 gallons cost will be multiply by 0.005 and for rest it will  multiply by 0.007. Then print the cost.

Output:

Enter the type of customer(B for business or R for residential):b                                                                                            

please enter the number of gallons:9000                                                                                                                      

total cost is: $56
