Answer:
<u>Up</u>. The focus is above the vertex meaning the parabola will open up. If the focus was below the parabola then it would open down.

<h3>Answer: 6.95</h3>
=====================================
Explanation:
The reference angle is angle S = 41 degrees. The side opposite that (RT) is unknown and what we want to find. The adjacent side to the reference angle is TS which is 8 units long.
RT = x
TS = 8
The ratio of the opposite and adjacent side is equal to the tangent of the reference angle, so,
tan(angle) = opposite/adjacent
tan(41) = x/8
--------------
We are given the value of tan(41) to be approximately 0.869, which means we will replace "tan(41)" with this decimal value and then isolate x by multiplying both sides by 8. This happens in the section below.
--------------
tan(41) = x/8
0.869 = x/8
8*0.869 = 8*x/8
6.952 = x
x = 6.952
x = 6.95
RT = 6.95
Step-by-step explanation:
Let's use the number represented x
x + 9 because 9 more than the x
(x+9)/-4 because it is divided by -4
(x+9)/-4 <= -2 (maximum of -2 means smaller than -2, but it also did not tell not to use -2)

= (x + 1)(3ab - 2)
