$11.28 so in total it would be $67.67
Answer: Magnitude =the square root of x^2+y^2
Since you are trying to find the magnitude, first understand what that means. Magnitude can be considered the “distance” between the initial and terminal points. So to solve this, all you need to do is plug in X and Y into the distance formula which is Magnitude =the square root of x^2+y^2
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 (
,
)
