If \( z \) varies inversely as \( w \), and \( z = 5 \) when \( w = 8 \), find \( z \) when \( w = 10 \).

[z\propto1/w
z=k/w
5=k/8
k=40]
If w=10,
[z=40/w
z=40/10
z=4]

When z varies inversely as w , we can find a constant k using the initial values. After calculating k , we can determine that if w = 10 , then z = 4 .
