Let's make the first even integer m and the second even integer n. The square of the first, decreased by the second is 130 is:
-n=130 ---> Add n to each side
=130+n ---> Take the square root of each side
m=±
Let's look at the first square number above 130, which is
. <em>m</em> is 12, therefore the next consecutive even integer is 14.
=144
144-14=130
The two consecutive integers are 12 and 14
m=±
Let's look at the first square number above 130, which is
144-14=130
The two consecutive integers are 12 and 14
The standard form of the equation of the parabola with the given characteristic(s) and vertex at the origin and directrix is y² = 16x.
<h3>What is the parabola?</h3>It is the locus of a point that moves so that it is always the same distance from a non-movable point and a given line. The non-movable point is called focus and the non-movable line is called the directrix.
Given that the parabola's vertex is located at the origin and that the directrix is at x = -4, the focus is at (4,0).
Then the equation can be written as
On squaring both sides, we have
