The function f(t)=|98.6-x|, represents a persons variance from normal body temperature, where x represents a persons current body temperature in degrees Fahrenheit. Medical professionals says healthy individuals should have a variance of no more than 0.5 degrees Fahrenheit

Step-by-step explanation:

Given the various variance of normal body temperature expressed by the function f(t) = |98.6-x| where x is persons current body temperature in degree Fahrenheit.

If medical professional says that healthy individual cannot have a variance of no more than 0.5F, we can get the variance by substituting x = 0.5 into the modeled function as shown;

Note that the function can either be negative or positive because of the modulus sign

If x = 0.5

For positive value,

f(0.5) = 98.6-0.5

f(0.5) = 98.1

If the function is negative

f(0.5) = -(98.6-0.5)

f(0.5) = -98.6+0.5

f(0.5) = -98.1

The variance for healthy individual will be expressed as -98.1≤f(x)≤98.1

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
