@Nnesha A farmer uses a lever to move a large rock. The force required to move the rock varies inversely with the distance from the pivot point to the point the force is applied. A force of 50 pounds applied to the lever 36 inches from the pivot point of the lever will move the rock. Which function models the relationship between F, the amount of force applied to the lever, and d, the distance of the applied force from the pivot point?
A. d=86/F
B. d=86/F
C. F=1,800/d
D. F=d/86

A and B are the same exact answers, which also confuses me.

nnesha · Answer

F varies inversely  with the distance 
so equation would be ?

same like last one

anonymous · Answer

instead of y and x it would be F and d, correct?

nnesha · Answer

yes right  f =y
d = x

anonymous · Answer

so the equation would be $$F=\frac{ k }{ d }$$

nnesha · Answer

yes right :-)

anonymous · Answer

Ok, I'll go try that and will let you know what I get.

nnesha · Answer

sure!

anonymous · Answer

I got C. $$F=\frac{ 1800 }{ d }$$

nnesha · Answer

yep that's the only  onemakes sense 
bec "d" which represent x should be at the denominator !

Thank you so much!! :)
