Find the standard form of the equation of the parabola with a focus at (0, 8) and a directrix at y = -8.
Gala2k [10]
Vertex is directly in middle of directix and focus

distance from 8 to -8 is 16
16/2=8
so 8 below focus (since 8>-8) is the point (0,0
vertex is (0,0)
nice

it opens up because focus is above directix
also it goes up down so
4p(y-k)=(x-h)^2
(h,k) is veretx
we got that (h,k) is (0,0)
and p is distance from vertex to focus which is 8
so
4(8)(y-0)=(x-0)^2
32y=x^2
y=(1/32)x^2

astronomers measure large distances in light years one light year is the distance that light can travel in one year or approxima
sveticcg [70]
What you can do in this case is the following rule of three to find the result:
 1 light year ---> 5.88 * 10 ^ 12 miles
 3.2 * 10 ^ 2 light year ---> x
 Clearing x we have:
 x = ((3.2 * 10 ^ 2) / (1)) * (5.88 * 10 ^ 12)
 x = 1.88 * 10 ^ 15 miles
 answer:
 In scientific notation, approximately it is 1.88 * 10 ^ 15 miles

-6 - 3(2x + 4) = 18what’s the answer
Brrunno [24]

Answer:

x=-6

Step-by-step explanation:

-6-3\left(2x+4\right)=18

Add 6 to both sides:

-6-3\left(2x+4\right)+6=18+6

-3\left(2x+4\right)=24

Divide both sides by -3:

\frac{-3\left(2x+4\right)}{-3}=\frac{24}{-3}

2x+4=-8

Subtract 4 from both sides:

2x+4-4=-8-4

2x=-12

Divide both sides by 2:

\frac{2x}{2}=\frac{-12}{2}

x=-6
