Variation can be direct, joint, inverse and combined.
The value of v when p = 4 is 2
The inverse variation is given as:
[tex]p = \frac{8}{v}[/tex]
Rewrite the equation of the inverse variation as:
[tex]pv = 8[/tex]
This is done by multiplying both sides of [tex]p = \frac{8}{v}[/tex] by v
Divide both sides of [tex]pv = 8[/tex] by p
[tex]v = \frac 8p[/tex]
When p = 4, the variation equation becomes
[tex]v = \frac 84[/tex]
Divide 8 by 4
[tex]v = 2[/tex]
Hence, the value of v when p = 4 is 2
