Hello All(adsbygoogle = window.adsbygoogle || []).push({});

I have this problem that I have no idea how to do.

F = flux or the volume of blood to flow past a point

R = radius

F=kR^4

Show that the relative change in F is about four times the relative change in R. How will a 5% increase in radius affect the flow of Blood??

How in the world do I do this?? What is Relative Change?? My text book does not have this term

I think I need to have 2 equations F = kR^4 and R = (F/k)^(1/4). Not sure what to do.

Please help.
