If the parabola is rotated so that its vertex is (h,k) and its axis of symmetry is parallel to the y-axis, it has an equation of (x - h)^2<span> = 4p(y - k)</span><span>, where the </span>focus<span> is (h, k+p) and the </span>directrix<span> is y = k - p. So, we need to determine the values from the equation.
</span><span>y=1/28(x-4)^2-5
</span>(x-4)^2 = 28(y+5)<span>
(h,k) = (4, -5)
p = 7
focus= </span>(h, k+p) = 4,2
directrix = y = k - p = -12
Hope this answers the question.

Step-by-step explanation:
Answer:
X=19m
Step-by-step explanation:
A=LxW
W=A/L=225/25=9m
Rope used =perimeter
4(x-2)=2L+2W
4x-8=2x9+2x25
4x=68+8
X=76/4=19m
