Answer:
Option A)
[tex]V = khr^5[/tex]
Step-by-step explanation:
We are given the following in the question:
V varies jointly as h and the fifth power of r.
[tex]V\propto h\\V\propto r^5[/tex]
Combing the two equations, we get,
[tex]V\propto hr^5[/tex]
Now, removing the sign of proportionality and adding the constant of proportionality, we get,
[tex]V = khr^5[/tex]
where k is the constant of proportionality.
Thus, the correct answer is
Option A)
[tex]V = khr^5[/tex]
