Part 1:
a = 2
b = 4
c = -3
Part 2: the parabola will open up
Part 3: axis of symmetry x = -1
There are 1000 milliliters per liter, so...
750 ml x 1 liter/1000 ml =
750/1000 = .75 liters
She received $221.72. If you divide 385.60 in half, because she sold half, you get 192.8. You then multiply that number by 1.15. There you have your answer.
I think The side is 90 in
Answer:
y = -
x²
Step-by-step explanation:
Since the vertex is at the origin and the focus at (0, - 4) then the parabola opens vertically down with equation
x² = 4py ( p is the distance from the vertex to the focus )
Here p = - 4 ( focus is below the vertex ), thus
x² = 4(- 4)y = - 16y ( divide both sides by - 16 )
y = -
x²
