Can someone please help me with these?
1. What are the focus and directrix of the parabola with the equation y=1/12 xsquared
2. what is an equation of a parabola with a vertex at the origin and directrix y=19/4
3. What are the focus and directrix of the given equation? y= -1/8 xsquared
4. what is an equation of a parabola with the given focus and directrix? vertex (0,0) directrix (0,5/2)
Smh. Here's the correct answers WITH the questions and what the letter stands for.
1. What are the focus and directrix of the parabola with the equation y=1/12x^2?
C focus: (0, 3) ; directrix: y = –3
2. What is an equation of a parabola with a vertex at the origin and directrix x = 4.75?
C x=-1/19y^2
3. What are the focus and directrix of the parabola with the given equation? x=-1/8y^2
D focus (–2, 0): directrix: x = 2
4. What is an equation of a parabola with the given vertex and focus?
vertex: (0, 0); focus: (2.5, 0)
C x=1/10y^2
Basically:
1. C focus: (0, 3) ; directrix: y = –3
2. C x=-1/19y^2
3. D focus (–2, 0): directrix: x = 2
4. C x=1/10y^2
