Another Facebook fan page I would like to talk about is the fan page of Groupon Hong Kong. I think it cannot effectively act as an advertising tool and build relation with audiences and visitors. First, the fan page cannot efficiently build awareness among target audiences. The fan page of Groupon has 7 years of development, it was set up in 2007 and already got 11,892,526 likes on its fan page. It seems that the fan page of Groupon is popular, but that’s is not the truth. After searching the

In the following exercises, determine whether each statement “makes sense” or “does not make sense” and explain your reasoning in 50 to 100 words for each answer. 1. I’m using an inverse variation equation and I need to determine the value of the dependent variable when the independent variable is zero. In this Rational expression it seems that the expression is considered undefined. My reasoning for this is because is because a rational expression does not have a value when it

UNIVERSITY OF JOS, NIGERIA October 13, 2009 ! Module 1: Functions 1 1.1 Objectives: In this module: We introduce with examples, the concept of a function and study some classes of functions. We discuss methods of nding the domain, range, zeros and singularities of some real-valued functions. We look at injective (one to one) and surjective (onto) functions and end the module by exploring the inverse of a function and the composition of functions. We stimulate students through classroom and other

(Cowboys, Troy Aikman),(49ers,Joe Montana),(Patriots,Tom Brady),(Rams,Joe Namath),(Chiefs, Joe Montana)} 2. Is the relation a function? Explain. (10 points) This is a function, because every element (Quarterback) of the domain is mapped to exactly one unique element (Team) of the range. So with the one to one relation of player to team, that makes this a function. 3. Now, use set Q as the domain, and set D as the range (reverse). Show the relation in the following forms: Set of ordered

wings and evolved their products into a device that’s sophisticated, yet rudimentary for the simplest user. For example, the iPad’s intuitive and ease of functionality is mainly due to the many gestures created to manipulate this device. Primary functions will launch and control applications (apps), simply with a swipe of the finger or by tapping the screen. These gestures are only the tip of an iceberg and many more vastly wait to be discovered. The Nielsen Norman Group (2011) titled “Usability

Diese Form der Algebra beschäftigt sich mit mathematischen Aussagen und ihren Verknüpfungen. Dabei gelten Aussagen als mathematisch, wenn sie klar als wahr (w) bzw. falsch (f) zu bezeichnen sind. Wahre Aussagen werden durch einer "1" dargestellt, falsche durch eine "0". Beispiel: Eine mathematische Aussage wäre: 1. Innsbruck liegt in Tirol. (wahre Aussage) 2. Das Münchner Gymnasium hat 10000 Schüler. (falsche Aussage) Dagegen aber keine mathematische Aussage wäre: 1. Schule

Espérance mathématique : Définition : de façon générale, l’espérance mathématique correspond à la moyenne des valeurs numériques pondérées avec la probabilité que ce réalise chacune de ces valeurs. Formule : E = p1xr1 + p2xr2 + p3xr3 + … + pnxrn Où p1, p2, p3, … ,pn correspond à la probabilité que les événements 1,2,3,…,n se réalisent Où r1, r2, r3, … ,rn correspond à la valeur numériques des événements 1,2,3,…,n Exemple : Un élève estime qu’il aura une note de 67% pour la compétence
