PLS HELP...ASAP
Which is the equation of a parabola with a directrix at y = -3 and a focus at (-2, 3).
y= 1/12(x - 2)²
y=1/12(x+2)²
y=-1/12(x + 2)²
y=-1/12(x-2)²

Step-by-step explanation:

If you plot the directrix, which is a horizontal line, then you plot the focus, which is above the directrix, you know that this parabola opens upwards (meaning it is positive), since a parabola always wraps itself around the focus, directed away from the directrix.  The standard form of this type of parabola is

where h and k are the coordinates of the vertex.  We were not given those coordinates, but we SHOULD know by now that the vertex is directly between the focus and the directrix, on the same axis of symmetry as the focus is.  So the vertex is located at (-2, 0).  Therefore, h = -2, k = 0.

P is defined as the distance between the vertex and the focus, or the vertex and the directrix, since they are the same.  Our p is 3 units.

Filling in our equation then gives us

and

and

The second choice is the one you want.

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.

happy to
