Answer:
"None of the answers are correct."
Step-by-step explanation:
The formula for Area given the circumference is A = ![\frac{C^{2} }{4\pi }](https://tex.z-dn.net/?f=%5Cfrac%7BC%5E%7B2%7D%20%7D%7B4%5Cpi%20%7D)
![\frac{26^{2} }{4\pi } = 53.79437](https://tex.z-dn.net/?f=%5Cfrac%7B26%5E%7B2%7D%20%7D%7B4%5Cpi%20%7D%20%3D%2053.79437)
So none of the above are correct

Answer:
Step-by-step explanation:
Let x represent the distance between Earth and its moons.
Saturn’s rings span up to about (7.5 × 10^-1) of the distance between the Earth and its moons. It means that Saturn’s rings span is
(7.5 × 10^-1)x
If Saturn’s rings span up to 2.82 × 10^5 kilometers, it means that
(7.5 × 10^-1)x = 2.82 × 10^5
Dividing both sides of the equation by 7.5 · 10^-1, it becomes
x = (2.82 × 10^5)/(7.5 × 10^-1)
x = 3.76 · 10^5 km
Use our brains and what we know
f(x)=a(x-h)²+k
vetex is (h,k)
and a is te leading coefient
if directix is below the focus, then it opens up and a is positive
if directix is above focus, then it opens down and a is negaitve
vertex is in between directix and focus
so
(3,-1) and y=1
-1<1
so directix is above
a is negative
directly in between
distance from -1 to 1 is 2
2/2=1
1 above (3,-1) is (3,0)
vertex is (3,0)
y=a(x-3)²+0
y=a(x-3)²
the only option with a negative 'a' value is B
answer is B
