Because 1 minute is 60 seconds, and it takes 12 seconds to download 8 apps, the first thing we need to do is find out how many "sets" of 12 seconds can go in 60 seconds:
60 / 12 = 5
Now, all we have to do is multiply the number of apps by 5, and we get our answer:
8 · 5 = 40
So, it would take Deandre 1 minute to download 40 apps.
X=55 since the triangle is 90*
The parabola is y² = 6x
This defines a parabola with its vertex at the origin (0,0).
When the equation is compared with y² = 4ax, then
4a = 6
a = 3/2
Therefore the focus is at
(a, 0) = (3/2, 0)
The directrix is located at
(-a, 0) = (-3/2, 0)
The parabola opens right because a > 0.
Answer:
The directrix is x = - 3/2.
The parabola opens right.

is the answer of the question
