Find the standard form of the equation of the parabola with a focus at (-4, 0) and a directrix at x = 4.
Huh like omg how can y’all understand that like my math teacher don’t teach us that we got easy stuff like we don’t have hard stuff like that is just 2 much

Answer: 2 inches</h3>
============================================================
Explanation:
The area of any given sheet of paper is 8.5*11 = 93.5 square inches.
Divide the volume over this area to get the height of the stack
187/(93.5) = 2
The stack is 2 inches tall.
Extra info: The thickness of each piece of paper is 2/500 = 0.004 of an inch which approximates to about 0.1016 mm.
The correct answer is x=4
In your problem about the finding the potential voltage at the center of the sphere where as its radius is 5cm is charge such that the potential of its surface is 10volts. So the possible answer to this is also 10 volts, because the potential in the center and in the surface of the sphere is constant and the same.
