Answer:
8√3 ≈ 13.86 ft
Step-by-step explanation:
The light source is usually placed at the focus, so the focus-vertex distance is p=3 ft. The equation for the parabola with its vertex at the origin is ...
y = 1/(4p)x^2
y = 1/12x^2
The opening for some y-value extends ±x from the axis of symmetry, so is a total of 2x in width.
For y=4, the corresponding value of x is ...
4 = 1/12x^2
48 = x^2
√48 = x = 4√3
Then the width of the searchlight opening is ...
2(4√3 ft) = 8√3 ft ≈ 13.86 ft

Answer: C, a woman whose father was a United States citizen
Step-by-step explanation: Your siblings do not affect your citizenship, so A is incorrect.
As for B, you need to go through a ton of legal stuff to become a citizen if you are born in a different country. D is incorrect because it legit makes zero sense. If you're from a country the US dislikes, it'll be even harder to become a citizen
