The is an interface between the user and the file system of a computer?

OS - Operating System acts as a interface between the user and the file system of the computer.

Explanation:

2. Operating System helps an individual to communicate with the computer without the language that the computer understands and interprets.

3. It has the privilege to have the access on the underlying  hardware.

answer: nobody

explanation:

start by isolating the variable on one side by adding 43w^2 to both sides.   the equation will read:

25w^2+5=0

*subtract 5 from both sides*

25w^2=-5

*divide both sides by 25*

w^2=-1/5

*take the square root of both sides*

w=√(-1/5)

the square root of -1 is i.   the square root of 5 remains √5

the answer is i/√5.

hope this
