It is the line of symmetry of a parabola and divides a parabola into two equal halves that are reflections of each other about the line of symmetry.
Answer:
<em>Distance ⇒ 5 meters</em>
Step-by-step explanation:
If we are to name the point with which Patrick stands P, Eddie's point E remains 4 meters south such that Dustin ( D ) is 3 meters to the right;
This in fact forms a 90 degree triangles, a right triangle with legs provided to be 4 and 3 knowing Eddie's remains 4 meters south, Dustin 3 meters to the right. If we are to determine how far apart Patrick and Dustin are, this is the hypotenuse of the right angle triangle formed, and the length can be determine through Pythagorean Theorem;
4^2 + 3^2 = x^2, x ⇒ distance between Patrick and Dustin,
16 + 9 = x^2,
x^2 = 25,
<em>Distance ( x ) ⇒ 5 meters</em>
2x +100=16+4x
-2x. -2x
100=16+2x
-16. -16
84=2x
divide both sides
x=42
