Chapter 1.3, Problem 54E

Temperature-humidity models Two models for measuring the effects of high temperature and humidity are the Summer Simmer Index and the Apparent Temperature. For an outside temperature of ${100}^0\text{F}$, these indices relate the relative humidity, H (expressed as a decimal), to the perceived temperature as follows.

Summer Simmer: $S=141.1-45.78\left(1-H\right)$

Apparent temperature: $A=91.2+41.3H$

For each index, find the point that corresponds to a relative humidity of $40\%$.

For each point in part (a), write a sentence that explains its meaning.

Graph both equations for $0\le H\le 1$.
