Afarmer uses a lever to move a large rock. the force required to move the rock varies inversely with the distance from the pivot 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?

f=1800/d Inverse proportion function. Provided f is in pounds & d is in inches.

Step-by-step explanation: the relationship between f & d is inverse proportion.

A constant k has to be derived from the relationship.

If f is inversely proportional to d then f=k(1/d)

K= f X d

= 50 X 36

=> constant K=1800.

step-by-step explanation:

the x's and the y's both go up the same amount each time, therefore it will be a linear function because it will go in a straight line when drawn on a graph.

hope this !
