Answer:
Match the methods:
See attached file
---------------------------------------------------------------------------------------------------------------------------------------
2)
Methods are public, and instance variables are private in common pattern of a class definition program.
So, the correct option is (C).

3) Java code:
//Create a Throttle called quiz with 100 positions<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
Throttle quiz = new Throttle(100);
//Method that shifts quiz's flow to the halfway
quiz.shift(50);
//Display the current flow from quiz.
System.out.println(quiz.getflow());

4)
Assume that the Foo class does not have a clone method. Then x is set to refer to a copy of y's object for an assignment x=y; in two Foo objects
.
So, the correct option is (A)

5)
The correct option is
A)
mower.top and copter.top will always be two separate instance variables.

Answer:
Yes, the side lengths of 1.5, 2.5, and 2 ft form a right triangle.
Explanation:
Before we solve this problem, we need to know a couple of things.
In a right triangle, you have two legs and a diagonal line that goes from one leg to the other or from one side to the other. This line is called the hypotenuse. It is the longest side of a right triangle. This length can be calculated by using a special formula that is over a thousand years old.
The formula is called the Pythagorean Theorem.
The formula states that if you square one leg and the other leg and add it up. You get the side of hypotenuse which is squared as well.
Here it is in simple terms: .
a and b are your two legs.
C is your hypotenuse.
In this case 1.5 and 2 are your legs and 2.5 is your hypotenuse since it is the longest side.
Before we calculate, there is a converse to the Pythagorean Theorem.
If , then it is not a right triangle.
Lets make 1.5 for a
and 2 for b.
We know 2.5 is for c.
Here it is.
. The / means it is a fraction.
1.5 squared is 9/4 and 2 squared is 4. Add 4 and 9/4 and you get 25/4 squared. Take the square root of 25/4 and you get 5/2.
5/2 is equal to 2.5, so the Pythagorean Theorem applies to this triangle. Therefore, these side lengths do form a right triangle.
Hope this helps!
