Question

For the inverse variation equation p=8/v, what is the value of v when p= 4?

A. 1/8
B. 1/2
c. 2
d. 32

Answer 1

For this case we have the following equation:
p = 8 / v
Clearing v we have:
v = 8 / p
Substituting the value of p = 4 we have:
v = 8/4
Rewriting we have:
v = 2
Answer:
c. 2

Answer 2

We are given:


`p= (8)/(v)`

and we are to find the value of v when p = 4. Using this value in above equation, we can write:


`4= (8)/(v) \\ \\ 4v=8 \\ \\ v= (8)/(4) \\ \\ v=2`

So, for p=4 the value of v will be 2.
Thus option C is the correct answer
