So hmmm check the picture below
so... the vertex is "p" distance from the focus and the directrix, thus, the vertex is really half-way between both
in this case, 2 units up from the focus or 2 units down from the directrix, and thus it lands at 3,3
now, the "p" distance is 2, however, the directrix is up, the focus point is below it, the parabola opens towards the focus point, thus, the parabola is opening downwards, and the squared variable is the "x"
because the parabola opens downwards, "p" is negative, and thus, -2
now, let's plug all those fellows in then
Answer: here the answer
Step-by-step explanation:
Answer:
Our required integers will be 9,11,19.
Step-by-step explanation:
Let three integers all less than 25 be x,y,z
Since we have given that
Range = 10
Mean = 13
These three integers will be
Since their range is 10 i.e.
And Mean = 13
