Answer:
2 + 8 =10 or it can be, 2 + 8 = 6 + 4
Answer:
the awnser would be a tangent of the plate i hope this helps
Step-by-step explanation:
In this problem, given the focus at (2,4) and directrix at y = 8. then it is implied that the parabola is facing downwards. The vertex hence is at the middle of the focus and the directrix, hence at (2, 6). The general formula of the parabola is y-k = -4a ( x-h)^2. Substituting, y -6 = -1/8 *(x-2)^2. Answer is A.
