the function f(t) = |98.6 - x| , represents a person's variance from normal body
temperature, where x represents a person's current body temperature in
degrees fahrenheit. medical professionals say healthy individuals should have a
variance of no more than 0.5°f.
part a: what can be said of an individual with a body temperature of 99.4°f?

part b: what can be said of an individual with a body temperature of 98.4°f?
justify your answer.
part c: what is a reasonable domain that would indicate the individual is not
healthy?

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
