Find the standard form of the equation of the parabola with a vertex at the origin and a focus at (0, -4).
1 answer:
We have
Parabola
with vertex (0,0) and focus (0,-4)
we know that
is a vertical parabola that opens down
the standard form of the equation is of the form
(x-h)²=-4p(y-k)
where
(h,k) is the vertex----------> (0,0)
p is the distance from the vertex to the focus or directrix
in this problem
p=4
(x-h)²=-4p(y-k)------> x²=-16y-------> y=-(1/16)x²
the answer is the option
<span>D.)y = negative one divided by sixteen x2
see the attached figure</span>

Answer:
Country A because it has a smaller interquartile range
Step-by-step explanation:
A smaller interquartile range connotes that the data in the distribution do not vary much, while a larger interquartile range would suggest the data vary much.
Therefore, the island that would have an average speed close to its median would be the island whose interquartile range is smaller.
Thus, Country A has a smaller interquartile range, so therefore, it would have a daily wind speed close to its median.
