Answer:

if (x > 7 && Math.sqrt(x) < 3)

Explanation:

The previous condition checks if the square root of x is less than 3, but this would raise an error if x is a value equal to or less than 0.

So, the condition checks for the value of x before evaluating the square root after the AND operation to prevent an arithmetic exception.

A ____ is a key-dependent, one-way hash function that allows only specific recipients(symmetric key holders) to access the messa

Alexxx [7]

Answer: (C) MAC

Explanation:

MAC is stand for the message authentication code and it is one of the key dependent hash function. Message authentication provide the data integrity and also the origin of data authentication.

It basically allow the specific recipients known as the holder of the symmetric key.
The message authentication code uses the CBC (Cipher block chaining) mode for constructing the MAC algorithm and it also uses the block cipher for the conjunction by using the CBC operations.

On the other hand, all the options are incorrect as they are not the key dependent hash function.

Therefore, Option (C) is correct.

Why do I have two random warnings?

Misha Larkins [42]

Just a guess, maybe you’ve been reported for having an incorrect answer two times? I’m really not sure I’m just trying to give out possibilities. Maybe if your a Brainly Helper you haven’t been active so they are giving you warnings? Does clicking on the warning tell you the reason for them? Maybe the system thinks your a robot? I’m not sure just trying to give possible reasons, but you could try contacting customer support, but they aren’t always the quickest at responding.

Have a good day!
