To solve this problem you must apply the proccedure shown below:
1. You have the following equation of a parabola, given in the problem above:
x<span>=1/16y^2
2. Then, based on the graph attached, you have:
p=y^2/4x
p=8^2/(4)(4)
p=64/16
p=4
3. The directrix is:
directrix=h-p
directrix=0-4
directrix=-4
The answer is:-4</span>
Answer:
QR and SV
RS and TU
Step-by-step explanation:
The critical value of r is mathematically given as r = +0.487, with no significant linear correlation. Option A.
<h3>What are the critical values of r?</h3>
Question Parameters
r = -0.868
n = 5
df = 5 - 2
df = 3
Critical values 
Generally, there exists no linear correlation between the Critical values
as r=0.878
In conclusion, Critical values: r = +0.487, no significant linear correlation

w + 4
------------------------
l l
l l w
l l
------------------------
Perimeter would be the sum of all the sides so: (w+4) + w + (w+4) + w
Perimeter is 60 yards according to your problem so: (w+4) + w + (w+4) + w = 60 yds
1.Simplify/combine like terms:
w + 4 + w + w + 4 + w =
4w + 8 =
Now it's a 2-step algebra equation
4w + 8 = 60
2.Subtract 8 on both sides
4w = 56
3.Divide both sides by 4
w = 14
Six million, seven thousand two hundred
