Answer:
The vertex is (0,0), focus of the parabola is , directrix of the parabola is , focal width is .
Step-by-step explanation:
The given equation of parabola is
It can be written as
....(1)
The general equation of parabola is
... (2)
Where, (h,k) is vertex, (h+p,k) is focus, y=h-p is directrix and |4p| is focal width.
On comparing (1) and (2), we get
The vertex is (0,0).
Focus of the parabola is
Therefore focus of the parabola is.
Directrix of the parabola is
Directrix of the parabola is.
Focal width is
Focal width is.
Answer:
B
Step-by-step explanation:
Look at |IH| as a clock arrow, it goes clockwise and the triangle is smaller so you have to dilate it by 2/3 because the G'H'I' is smaller
To find the equation of a line parallel to a given line, identify the slope of the given line and choose any point on that line, then use the point-slope formula to find the equation of the parallel line.
