tina(90)
tina.back(90)
tina.left(90)
tina.right(90)
Answer:
tina.left(90)
Explanation:
In code if you want your character to turn left you put "left" in your code and if you want your character to go right type "right" and so on and so on so your answer is tina.left(90)
Answer: Option C is the correct line of code Tori should use.
tina.left(90)
Explanation:
I took the test and got it correct, you can trust me.

The template code provided is intended to take two inputs, x and y, from the user and print "pass" if one or more of the following is true:
x is not less than 4
y is not greater than 5 and x + y is less than 7
However, when using De Morgan's law to simplify this code, the programmer has made some mistakes. Can you correct the errors so the code functions as intended?
/* Lesson 6 Coding Activity Question 2 */
import java.util.Scanner;
public class U3_L6_Activity_Two{
public static void main(String[] args){
Scanner scan = new Scanner(System.in);
int x = scan.nextInt();
int y = scan.nextInt();
if(!((x 5) || x+y > 7))
System.out.println("pass");
}
}
import java.util.Scanner;
public class U3_L6_Activity_Two{
public static void main(String[] args){
Scanner scan = new Scanner(System.in);
int x = scan.nextInt();
int y = scan.nextInt();
if(x>=4|| ((y < 5) && ((x+y) < 7))){
System.out.println("pass");
}
}
}
I'm pretty sure this is what you're looking for. Best of luck.
For formatting and readability sake, the given code is re-written as follows:
/* Lesson 6 Coding Activity Question 2 */
import java.util.Scanner; // 1
public class U3_L6_Activity_Two{ // 2
public static void main(String[] args){ // 3
Scanner scan = new Scanner(System.in); // 4
int x = scan.nextInt(); // 5
int y = scan.nextInt(); // 6
if(!((x 5) || x+y > 7)) // 7
System.out.println("pass"); // 8
}
}
The line that needs to be fixed is the if statement in line 7.
As given in the instruction, the code prints "pass" if one or more of the following is true:
i. x is not less than 4. This can be re-written as;
! ( x < 4 )
ii. y is not greater than 5 and x + y is less than 7. This can be re-written as;
! (y > 5) && (x + y < 7)
To have the right operand of ii to have a negation, we can re-write as follows;
! (y > 5) && ! (x + y > 7) (i.e changing the less than sign to greater than and then putting the negation sign (!)). This is great so that the De Morgan's law will be applicable on both sides.
Note:
a. ! is the Java's equivalent way of writing the logical operator NOT
b. && is the Java's equivalent way of writing the logical operator AND
Since one or more of the conditions in (i) and (ii) need to be true before the "pass" is printed, we can combine (i) and (ii) using the OR operator ( || ) as follows;
! ( x < 4 ) || ( ! (y > 5) && ! (x + y > 7) ) ----------------(***)
The De Morgan's laws are very great for making deductions, equivalence and valid proofs when using logical operators.
The laws are as follows;
i. ∼ (P ∧ Q) = ∼ P ∨ ∼ Q
This can be written as;
! (P AND Q) = ! P OR !Q
or in Java like syntax as
! (P && Q) = ! P || !Q
ii. ∼ (P ∨ Q) = ∼ P ∧ ∼ Q
This can be written as;
! (P OR Q) = ! P AND !Q
or in Java like syntax as
! (P || Q) = ! P && !Q
Using these laws, we can simplify our expression in (***) as follows;
! ( x < 4 ) || ( ! (y > 5) && ! (x + y > 7) )
a. Start with the right side i.e ( ! (y > 5) && ! (x + y > 7) )
The De Morgan's law (stated in (ii) above) will remove the negation from both terms in the right side term, change the && to || and then put a single negation to apply to both terms in the bracket to give the following;
! ( x < 4 ) || ! ( y > 5 || x + y > 7 )
b. Now, there are two main terms - ! ( x < 4 ) and ! ( y > 5 || x + y > 7 ) separated by ||
Apply the De Morgan's law (stated in (i) above) to remove the negation from both terms, then change the || to && and then put a single negation to apply to both terms.
! ( x < 4 && (y > 5 || x + y > 7))
The result in b is the simplified version of the condition in the if statement.
The complete and corrected code is therefore written as follows;
/* Lesson 6 Coding Activity Question 2 */
import java.util.Scanner; // 1
public class U3_L6_Activity_Two{ // 2
public static void main(String[] args){ // 3
Scanner scan = new Scanner(System.in); // 4
int x = scan.nextInt(); // 5
int y = scan.nextInt(); // 6
if(! ( x < 4 && (y > 5 || x + y > 7) ) ) // 7
System.out.println("pass"); // 8
}
}

Anisha was learning ‘for’ and ‘while’ loop. Help her understand why for and while loops are called entry controlled loops.
Entry controlled loop - The loop which has a condition check at the entrance of the loop, the loop executes only and only if the condition is satisfied is called as entry control loop.
So, for and while loops are its examples.
How has technology effected the way we communicate?
Indeed it has.
Advancements in technology and changes in communication generally go hand in hand. Landlines displaced the telegraph and cell phones replaced landlines. The arrival of the internet opened new doors of personal communication. E-mails replaced postal mails and social media took the place of text messages.
Communication technology, such as mobile phones, email, text messaging, instant messaging and social networking have had a profound effect on nearly everyone's business and personal lives. While technology makes communications faster and easier, at times it can also be intrusive and misinterpreted.
Increased isolation, reduced social interaction and social skills, and increased human-to-machine interactions are all a result of an overuse of technology, which has created a wall between many people globally.
Technology has the ability to enhance daily living from appliances to mobile devices and computers, technology is everywhere. ... In the rise of digital communication, technology can actually help communication skills because it allows people to learn written communication to varying audiences.

Write a program with a method called passwordCheck to return if the string is a valid password. The method should have the signature shown in the starter code.
The password must be at least 8 characters long and may only consist of letters and digits. To pass the autograder, you will need to print the boolean return value from the passwordCheck method.
Hint: Consider creating a String that contains all the letters in the alphabet and a String that contains all digits. If the password has a character that isn’t in one of those Strings, then it’s an illegitimate password!
import java.util.Scanner;
public class JavaApplication46 {
public static boolean passwordCheck(String pass){
String alphanum = "abcdefghijklmnopqrstuvwxyz1234567890";
boolean legit = true;
if (pass.length()>= 8){
for(int i = 0; i < pass.length(); i++){
if (alphanum.indexOf(pass.charAt(i)) != -1 && legit != false){
legit = true;
}
else{
legit = false;
}
}
}
else{
legit = false;
}
return legit;

public static void main(String[] args) {

Which component in a CPU is responsible for transferring
data from one functional component to another?
PLS HURRY!!
Look at the image below
Answer:
1. A function can use variables as parameters.
2. A function can have more than one parameter.
3. The definition of a function must come before where the function is used.
Explanation:
The definition of a function can come before or after it is used - I am pretty sure it cannot be placed after the function is being used. It should always come before it is used, so this statement is false.
A function can use variables as parameters - this is true, variables are just labels to hold data.
A function can have more than one parameter - this is true.
A function must have a return value - functions do not always have to return values. It could simply print, so this statement is false.
The definition of a function must come before where the function is used - As said earlier, the definition of functions must come before it is used/called. This statement is true.
