52. Heat of a Campfire The heat experienced by a hiker at a campfire is proportional to the amount of wood on the fire and inversely proportional to the cube of his distance from the fire. If the hiker is 20 ft from the fire and someone dou- bles the amount of wood burning, how far from the fire would he have to be so that he feels the same heat as before?
Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
Heat of a Campfire The heat experienced by a hiker at a
campfire is proportional to the amount of wood on the fire
and inversely proportional to the cube of his distance from
the fire. If the hiker is 20 ft from the fire and someone doubles the amount of wood burning, how far from the fire
would he have to be so that he feels the same heat as
before?
