Write the equation of a parabola with a vertex at (0,0), a focus at (2,0), and directrix x=-2
kkurt [141]
The directrix is x=-2, which means the parabola opens horizontally instead of vertically. The equation is (y - k)²<span> = 4p (x - h), where the </span>focus<span> is (h + p, k) and the </span>directrix<span> is x = h - p
in this case, h+p=2, k=0, and h-p=-2
solve for h and p: h=0, p=2
plug the numbers into the equation: (y-0)</span>²=4*2(x-0)

width=3m

length=9m

Step-by-step explanation:

-Let w be the width of the garden.

-Given that the length is 6 units more than the width, l=w+6

-We apply the area formula to solve for w:

A=lw\\\\27=w(w+6)\\\\w^2+6w-27=0\\\\\#Apply \ Complete \ Squares\\\\w^2-3w+9w-27=0\\\\w(w-3)+9(w-3)=0\\\\(w-3)(w+9)=0\\\\w=3 \ \ \or w=-9\\\\\therefore w=3m\\\\l=w+6=3+6=9m

Hence, the garden's width is 3 m and the length is 9 m
