A parabola with an equation, y2 = 4ax has its vertex at the origin and opens to the right.
It's not just the '4' that is important, it's '4a' that matters.
This type of parabola has a directrix at x = -a, and a focus at (a, 0). By writing the equation as it is, the position of the directrix and focus are readily identifiable.
For example, y2 = 2.4x doesn't say a great deal. Re-writing the equation of the parabola as y2 = 4*(0.6)x tells us immediately that the directrix is at x = -0.6 and the focus is at (0.6, 0)
What else can I help you with?
In the equation s equals d divided by t what does d stand for?
The d stands for distance.
What does Emc square mean?
E = mc squared is a famous equation devised by Albert Einstein that demonstrates the way in which matter and energy are connected. E stands for energy, m stands for mass or matter, c stands for the speed of light."Energy equals mass times the speed of light squared." On the most basic level, the equation says that energy and mass (matter) are interchangeable; they are different forms of the same thing.
What is the value of x given the equation 3x plus 4 plus 5x-6?
Oops! That's not an equation. It has no 'equals' sign ( ' = ' ) in it, so it's just an 'expression' that stands for a number. The number that it stands for depends on the value of 'x', and any time 'x' changes, the value of the expression changes.
What is the sum to e equals mc2?
There is no sum of e=mc2, it is an equation concerning matter and energy. e=mc2 stands for: Energy equals mass times the velocity of light squared. E = M C 2
What does c stand for in e equals mc?
The 'c' in that equation stands for the speed of light in a vacuum. If the equation is being evaluated in metric units, then it's 299,792,458 meters per second. If in English units, then it's 186,282 miles per second.

The equation E equals mc2 stands for?
The equation E=mc^2 stands for "energy equals mass times the speed of light squared." It expresses the concept that energy (E) and mass (m) are interchangeable, with the speed of light (c) acting as the conversion factor. The equation is a fundamental principle of physics, demonstrating the relationship between energy and mass.
