Conduct a 15 to 30 minute interview with an airline or airline supplier sales/marketing employee. The interview can be conducted in person, over the phone, through a cyber chat or Skype. The person you choose to interview must be in sales or marketing, those in other positions such as flight operations, baggage, maintenance, etc., are not acceptable. Examples: an employee selling freight, ticket sales agents, marketing communications, pricing analyst, and a marketing executive.

Sample Solution

Pi is generally known as a series of numbers beginning from 3.14. In any case, it is considerably more than that. It is a scientific consistent. Initially, it was characterized as the proportion of a hover's boundary to its width. In any case, it currently has different definitions and is in numerous equations in science and material science. Despite the fact that it is classified "pi" in English, it generally spoke to by the Greek letter "p." Anyway, in the accompanying passages, we will really expound on its basics, history, and job. Pi is the most known numerical consistent. As was referenced in the presentation, it rises to the boundary of a hover separated by the measurement. As per LiveScience, "Regardless of how enormous or little a circle is, pi will consistently work out to be a similar number. That number equivalents roughly 3.14, yet it's somewhat more muddled than that" (Hom, Elaine J.). Pi is likewise noted as a nonsensical number, which fundamentally focuses to the way that is a genuine number that can be appeared as a straightforward portion. Actually, it is the thing that mathematicians call a "boundless decimal," as pi's digits go on for eternity. Additionally, there are no rehashing examples in pi. Since pi's digits go on always, mathematicians and researchers regularly inexact it. As indicated by Wonderopolis, "For most purposes, pi can be approximated as 3.14159. A few people even abbreviate it to 3.14, which is the reason Pi Day is commended on March 14 (3/14)" ("What Is Pi?"). Is intriguing that PCs have determined pi to more than three trillion digits. A few people even recall 1000s of digits of pi as a psychological exercise. In any case, where did this number originate from? Shockingly, this recipe has been being used for more than 4000 years. The main individuals to find pi was the Babylonians. As indicated by Exploratorium, "The antiquated Babylonians determined the zone of a hover by taking multiple times the square of its range, which gave an estimation of pi = 3. One Babylonian tablet (ca. 1900–1680 BC) demonstrates an estimation of 3.125 for p, which is a closer guess. The Egyptians determined the zone of a hover by an equation that gave the inexact estimation of 3.1605 for p" ("A Brief History of Pi (p)"). In any case, the principal estimation of pi was finished by Archimedes (287–212 BC). However, he realized he didn't discover the estimation of pi, yet rather a guess of its worth, with him expressing that pi was between 3 1/7 and 3 10/71. Pi has numerous jobs. In science, "Most geometry understudies first experience pi when they study circles and discover that the zone of a circle is equivalent to pi times the square of the length of the span." It is additionally utilized generally in trigonometry. Formulae concerning circles, circles, or ovals regularly use pi. Here are some basic formulae that utilization it: The outline of a hover with range r is 2pr. The territory of a hover with range r is pr2. The volume of a circle with span r is 4/3pr3. The surface territory of a circle with range r is 4pr2. (A Guide Book to Mathematics) In material science, pi is additionally ordinary. As per LiveScience, "Pi additionally shows up in the material science that depicts waves, for example, waves of light and sound. It even goes into the condition that characterizes how exactly we can know the condition of the universe, known as Heisenberg's vulnerability rule. A waterway's breeziness is dictated by its "wandering proportion," or the proportion of the stream's genuine length to the good ways from its source to its mouth straight from one point to the other" (Wolchover, Natalie). Subsequently, pi has numerous applications in material science too. Pi is shockingly in mainstream society. There is an even a day celebrated for this numerical consistent. Be that as it may, most don't have the foggiest idea about that it was first found by the old Babylonians and refined by Archimedes. Additionally, numerous individuals don't have the foggiest idea about that it is a silly number that equivalents the outline of a hover partitioned by the measurement. This extraordinary equation has numerous applications in science, material science, and considerably more territories. Works Cited Hom, Elaine J. "What Is Pi?"
