Answer:

y = [tex]\frac{1}{4}[/tex]

Step-by-step explanation:

Given that y varies inversely with x then the equation relating them is

y = [tex]\frac{k}{x}[/tex] ← k is the constant of variation

To find k use the condition y = 16 when x = [tex]\frac{1}{2}[/tex]

k = yx = 16 × [tex]\frac{1}{2}[/tex] = 8

y = [tex]\frac{8}{x}[/tex] ← equation of variation

When x = 32, then

y = [tex]\frac{8}{32}[/tex] = [tex]\frac{1}{4}[/tex]
