Find the equation of the directrix of the parabola: 1/12*x^2=y explain and show your work.

Step-by-step explanation:

We have been an equation . We are asked to find the equation of directrix for our given parabola.

We know that standard form of parabola is in form with vertex at point and focal length of .

Let us convert our given equation in standard form as:

The vertex of our given parabola is (0,0) and focal length is p.

The equation of directrix is in form .

From our given equation, we can see that .

So the equation of directrix will be

Therefore, the equation of directrix is .

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
