write an equation of the parabola with vertex at the origin and the given focus or directrix.

1. focus at (3,0)
2. focus at (0,-5)
3. directrix y=2
4. directrix x=-4

solve each equation using perfect square trinomials.
1. 9x^2+12x+4=64

2 x^2 -3x+p

sum of roots = 3/2

let other root be x

3+ x = 3/2

x= 3/2 - 3 = -3/2

product of roots = p/2

3× -3/2 = p/2

-9 = p

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

its a straight line parallel to the time axis
