Suppose a reference variable of type integer called myint is already declared. create an object of type integer with the initial value of 1 and assign it to the reference variable myint.

//The class called "Solution" is declared

public class Solution {

 //Main method which signify the beginning of program execution    

 public static void main(String[] args) {

   //myInt variable of type Integer is declared  

   Integer myInt;

   // An object of type Integer is declared with initial value of 1

   Integer newInt = new Integer(1);

   // The value of the new declared and assigned object is displayed to the user

   System.out.println(newInt);

   // The new declared object is assigned to the reference variable myInt

   myInt = newInt;

   // The value of myInt is displayed to the user

   System.out.println(myInt);

 }

}

Step-by-step explanation:

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
