Given the equation x^{2} = 8y what are the coordinates of the focus

Focus ->

Step-by-step explanation:

Because the x-term is squared, the parabola must be vertical.

Recall that the equation for a vertical parabola is where is the distance from the vertex to the focus and are the coordinates of the focus.

We can tell by the given equation that the vertex must be located at the origin.

Therefore, we can determine the value of having known the vertex and the direction of the parabola:

So, given that , this means that the coordinates of the focus are .

the answer is: the length is 5/6 yards.

give me a or a 5 star rating if this is correct!

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
