write the equation that expresses the relationship between the variables, and then use the given data to solve for the variation constant k.
d varies directly as f and inversely as the square root of g,
:
the equation for this:
d = {{{(kf)/sqrt(g)}}}
:
and d = 0.04 when f = 8 and g = 0.04 
.04 = {{{(8k)/sqrt(.04)}}}
:
.04*{{{sqrt(.04)}}} = 8k
.008 = 8k
k = {{{.008/8}}}
k = .001
:
d = {{{(.001f)/sqrt(g)}}}, is the equation</PRE>
