Answer:
discriminant = b * b - 4 * a * c
discriminant = b ** 2 - 4 * a * c
Explanation:
The operands are correct and in the right order (for python).
** is the operand for squaring something.
* is the operand for multiplying something.
- is the operand for subtracting something.
I’m pretty sure it would be “A novel assigned in English class” (algorithm is a process or set of rules to be followed in calculations or other problem-solving operations, especially by a computer.) Example: the recipe for baking a cake.
Answer:
The right response is "Robots
".
Explanation:
- A robot seems to be an independent machine that can detect its surroundings, conduct simulations, as well as take action throughout the modern or actual environment.
- It is indeed a piece of computer-controlled equipment, which would also be utilized autonomously for carrying out duties or other hazardous tasks.
Answer:
2. <em>A reference of type A can be treated as a reference of type B</em> - False
Base class or its objects are not related to their derived class (or its objects).
Explanation:
class A {
int a;
public A() {
a = 7;
}
}
class B extends A {
int b;
public B() {
b = 8;
}
}
///////////////////////////////////////////////////////////////////////////////////////////////////////
1. <em>After the constructor for class B executes, the variable a will have the value 7 </em>- True.
When an object of a derived class is declared, the constructor of base class is called before the constructor of derived class (is called).
3. <em>Both variables a and b are instance variables </em>- True.
Classes can have instance, or member, variables and methods.
4.<em> After the constructor for class B executes, the variable b will have the value 8</em> - True.
When object of class B is declared, its constructor was called, which initialized variable b to 8.
The answer should be RAM = Random Access Memory
RAM memory is used to store current data while the computer is on. Bear in mind that after the computer is shutdown all data in RAM is lost.
