Answer:
To make 6 cups, you will need 2 cups of lemon and 4 cups of water....6 total
TWO of the six are lemon 2/6 x 100 = 33.33% Lemon the rest is water 100-33.33= 66.67% water
OR
FOUR out of the SIX are water 4/6 x 100 = 66.67% Water
Step-by-step explanation:
Standard form is, hold a sec
x=2 is directix
that means it opens left or right
so we must use
(y-k)²=4p(x-h)
where vertex is (h,k) and p is distance from focus to vertex
also shortest distance from vertex to directix
the shortest distance from focus to directix is 2p
if p>0 then the parabola opens right
if p<0 then pareabola opens left
so
(-2,0) and x=2
the distance is 4
4/2=2
p=2
wait, positive or negative
focus is to the left of the directix so p is negative
p=-2
vertex is 2 to the right of the focus and 2 to the left of directix
vertex is (0,0)
so
(y-0)²=4(-2)(x-0) or
y²=-8x is da equation
not sure what form is standard tho
