#### Solutions

Chapter 1.11, Problem 46E
To determine

## To find:The equation given that the statement

Expert Solution

The fire feels the same heat as before xn=2023ft

### Explanation of Solution

Given:

H varies inversely x3 or v is inversely proportional to x3

Concept used:

If the quantities x and y are related by an equation

y=kx

For some constant k0

That is y varies inversely as x or y is inversely proportional to x

The constant k is called constant proportionality

Calculation:

If the quantities H,w and x3 are related by an equation

Hαwx3

H=kwx3

For some constant k0

That is H varies inversely x3 or v is inversely proportional to x3

The constant k is called constant proportionality

x=20ftwn=2wHn=Hkwx3=kwxn3w203=2wxn3xn3=(2×203)xn=2023ft
