60/6000 = x/1423
100/1 = 1423/x
100x = 1423
x = 14.23 --> About 14 cm

Answer:
the 2nd one
Step-by-step explanation:
just substitue values.
Considering the equation of the parabola, the directrix is: x = 1.
<h3>What is the equation of a parabola given it’s vertex?</h3>
The equation of an horizontal parabola, of vertex (h,k), is given by:
(y - k)² = 4p(x - h).
The directrix is at x = h - p.
For this problem, the equation is:
(y + 3)² = 8(x - 3).
The relevant coefficients for this problem are:
4p = 8 -> p = 2, h = 3.
Hence the directrix is:
x = h - p = 3 - 2 = 1.
