Which of the following can replace / missing code / so that the statement works as intended?
Math.sqrt((x + y)
2/ Math.abs(a, b))
Math.sqrt((x + y) 2/ Math.abs(a - b))
Math.sqrt(Math.pow(x + y, 2) / Math. abs(a, b))

Consider the following code segment, which is intended to print the digits of the two-digit int number
num in reverse order. For example, if num has the value 75, the code segment should print 57.
Assume that num has been properly declared and initialized.

Mark for Review
Which of the following best describes the behavior of the code segment?
The code segment does not work as intended because the expression
(val +0.5) should be cast to a double instead of an int
The code segment does not work as intended because val should be cast
to an int before 0.5 is added to it.
