16 - x = 27
x = -11
16 - x = 27
16 = 27 + x
16 - 27 = x
-11 = x
It is 2 inches long this is because of the length of the hands .
The distance between the focus and directrix is, in this case, 8. Since the directrix is at x= something, the parabola opens sideways, and since the directrix is on the left, to the right. In which case, y^2=p(x), where p is 4 times distance of half of distance between directrix and focus, so the answer is y^2=16x
