My brain just kind of exploded when reading this, please help!​
zhannawk [14.2K]

Answer:

4.8 liters

Step-by-step explanation:

o=orange juice c=cranberry juice

Punch = 4/5o + 1/6c  it means that any quantity of punch will have the same proportion of the two ingredients

now, you know that 1 liter can be written as 6/6 liters, so to get those 6/6 you multiply 1/6 by 6

for the proportion to remain valid, you must multiply by 6 also the other ingredient so (4/5)*6 = 24/5 of a liter of orange juice per liter of cranberry juice and 24/5 = 4.8 liters

Using a directrix of y = −3 and a focus of (2, 1), what quadratic function is created?
Lelechka [254]

Answer:

  y=\dfrac{1}{8}(x-2)^2-1

Step-by-step explanation:

The distance between the focus and the directrix is the vertical distance from the point to the line:

  1 -(-3) = 4

The vertex is half that distance between the point and the line, so is at x=2 and ...

  y = (-3 +1)/2 = -1

The vertical scale factor of the quadratic is 1/(4p) where p is the distance from vertex to focus. Here, that distance is 2, so the equation in vertex form is ...

  y = (1/(4·2))(x -2)² -1

  y = (1/8)(x -2)² -1

_____

<em>Check</em>

Any point on the parabola is equidistant from the focus and directrix. This is easily checked at the vertex, which is halfway between focus and directrix, and at the points having the same y-value as the focus. Those two points are (-2, 1) and (6, 1), both of which are 4 units from the focus and 4 units from the directrix.
