The equation of a parabola is given. y=
Here the value of 'a' = 18 and it is positive, it means the parabola opens up.
For vertical parabola the focus point is (h , k+p)
Where (h,k) is the vertex and p = (p is the distance between vertex and focus)
First we find vertex (h,k)
h =
a = 18 and b = 4
So h= = =
Plug in -1/9 for x and find out k
k =
=
=
So vertex is (, )
P = , we know a= 18
So p = =
Focus is ( h, k +p)
h = k =
and p =
k + P = +
Take common denominator 72
k + p = + = =
Focus point is ( , )

THEN YOU GET YOUR ANSWER.
Answer:
2 : 5
Step-by-step explanation:
In order to obtain the ratio between numbers, we divide by the largest common factor between both.
In this question, the numbers are;
36 : 90
The largest common faction is 18. Dividing both numbers by 18, we have;
36 / 18 : 90 / 18
2 : 5
The ratio is; 2 : 5
