Answer: 
<u>Step-by-step explanation:</u>
Given: cos x =
, x is in Quadrant 4
Use Pythagorean Theorem to find sin x:
8² + y² = 17²
y² = 17² - 8²
y² = 289 - 64
y² = 225
y = 15
→ sin x = 
Use the double angle formula to find cos (2x):

140 divided by 14 is 10. So x is 10. And Y is 140. 140 divided by y (1) =140
Answer:
Option A)

Step-by-step explanation:
We are given the following in the question:
V varies jointly as h and the fifth power of r.

Combing the two equations, we get,

Now, removing the sign of proportionality and adding the constant of proportionality, we get,

where k is the constant of proportionality.
Thus, the correct answer is
Option A)
