Answer:
The operation of 6*x only executes if x is greater or equal to 0, since x=-10 and -10 is less than 0, the operation does not execute. For this reason, the value of y using this code is None.
Explanation:
In python a function is defined with the syntaxis:
def function(x):
the operation to execute (x)
value to return
In this case, the function is foo and the parameter is x:
def foo(x):
if x>= 0:
return 6*x
The code starts by assigning a value to x. Then, the code asks if the value of x is grater or equal to 0, if this condition is meet, then the code returns the value of 6 times x, if not, then the code does not return a value. In this case, x is -10 and this value is not grater or equal to 0. Given that the condition is not met, then the code stops executing and the value of y is none.
The flashing yellow light indicates that people should be aware of other cars and turn carefully. To be more safe, you should slightly slow down, make sure all signals that should be on are on, and you should drive very carefully.
Here you go,
import java.util.Scanner;
import java.util.Random;
public class OrderCalculator{
public static void main(String[] args){
float x, y, z, semi, area;
Scanner in = new Scanner(System.in);
System.out.print("Enter the 3 sides: ");
x = in.nextFloat();
y = in.nextFloat();
z = in.nextFloat();
semi = (float) ((x + y + z) / 2.0);
area = (float) Math.sqrt(semi * (semi - x) * (semi - y) * (semi - z));
System.out.printf("The area is: %.3f\n", area);
}
}
Answer:
for(var i=0; i<3; i++) {
penUp();
moveTo(100,120);
turnTo(180);
penDown();
moveForward(25);
}
Explanation:
The i variable is the loop dummy. The code block will be executed 3 times.
