Question 620274: I can't figure this out.... the question is.... 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, and d = 0.04 when f = 8 and g = 0.04
d=
k=

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 = %28kf%29%2Fsqrt%28g%29
:
and d = 0.04 when f = 8 and g = 0.04
.04 = %288k%29%2Fsqrt%28.04%29
:
.04*sqrt%28.04%29 = 8k
.008 = 8k
k = .008%2F8
k = .001
:
d = %28.001f%29%2Fsqrt%28g%29, is the equation
