Given
Required
Determine the distance between M and S
Distance (D) is calculated using:
Where
<em>Hence, the distance between M and S is 18 units</em>
<em></em>
14.
The coordinate of S and P are not given,
So, I'll just use (x,y) for P
i.e.
Required
Determine the coordinates of S
If S is 6 units above P, then the coordinates of S is
<em>i.e. we add the units to the y coordinate of P.</em>
Check the picture below. So the parabola looks more or less like so.
let's recall that the vertex is half-way between the focus point and the directrix, at "p" units away from both.
Let's notice that the focus point is below the directrix, that means the parabola is vertical, namely the squared variable is the "x", and it also means that it's opening downwards as you see in the picture, namely that "p" is negative, in this case "p" is 1 unit, and thus is -1.
