MCQ

// MCQ 1
int n = (int) Math.pow(2, 3.0 / 2);
System.out.println(n);
// Output: 2 There answer is A

// MCQ 2
int r = (int) (Math.random() * 6) + 5;
System.out.println(r);
// Output: 5 to 10 There answer is A

// MCQ 3
long a = Math.round(-3.5);
double b = Math.floor(-3.1);
double c = Math.ceil(-3.1);
int x = (int) a + (int) b + (int) c;
System.out.println(x); 
// Output: -10 There answer is A

-10

Which expression correctly computes the Euclidean distance between points (x1, y1) and (x2, y2)?

A.
Math.sqrt(Math.pow(x2 - x1, 2) + Math.pow(y2 - y1, 2))

B.
Math.pow((x2 - x1) + (y2 - y1), 2)

C.
Math.abs((x2 - x1) + (y2 - y1))

D.
Math.sqrt(Math.pow(x2 + x1, 2) + Math.pow(y2 + y1, 2))

Answer is A.

int a = (int) Math.sqrt(26);
int b = (int) Math.sqrt(26);
System.out.println(a * b);
// Output: 25 There answer is B
