we are given with the data of a parabola with vertex at (2, 2) and directrix at y = 2.5. the formua should be ax^2 + b x + c = y because of the directrix.
(x-h)^2 = 4a (y-k)
(x-2)^2 =4a (y-2)
a is the equidistant distance from focus to vertex and from vertex to directrix that is equal to -0.5
then the answer is
(x-2)^2 =-0.5*4 (y-2)
x2 - 4x + 4 = -2y +4
x2-4x+2y = 0
answer is C
#4 is D 8.5 oz, do 3.4 / .4
#5 is C .96$, do (3/4)x=36 and you get 48 x .02 and you get .96
if this helps please mark branliest, Trying to rank up haha

Step-by-step explanation:
Percent decrease =
(difference in prices)/(original price) × 100
(2.89 - 2.82)/2.89 × 100
= (0.07)/2.89 ×100 ≈ 2.4%
