The focus of a parabola is located at (0,–2). The directrix of the parabola is represented by y = 2. Which equation represents t

Archy [21]

Answer:

$\boxed{x^2=-8y}$

Step-by-step explanation:

$(a,b)\ is \ the\ focus\\y=k\ is \ the\ directrice\\\\Formula\ to\ use:\ y=\dfrac{(x-a)^2}{2(b-k)} +\dfrac{b+k}{2} \\\\Here: \ a=0,\ b=-2, \ k=2\\\\y=\dfrac{(x-0)^2}{2(-2-2)} +\dfrac{-2+2}{2} \\\\so\ y=-\dfrac{x^2}{8} \\\\or\ x^2=-8y$

I think x = 78
because 21/14 = 1.5
so x = 1.5*52

Two grandparents want to pick up the mess that their granddaughter had made in her playroom. One can do it in 15 minutes working

Crank

Answer:

6 2/3 minutes

Step-by-step explanation:

Their rates in "jobs per hour" are ...

(60 min/h)/(15 min/job) = 4 jobs/h

and

(60 min/h)/(12 min/job) = 5 jobs/h

So, their combined rate is ...

(4 jobs/h) + (5 jobs/h) = 9 jobs/h

The time required (in minutes) is ...

(60 min/h)/(9 jobs/h) = (60/9) min = 6 2/3 min

Working together, it will take them 6 2/3 minutes.
