URGENT svp pouvez vous m'aider à répondre à la question, je comprend pas Voici le texte : Richard McDonald designed a new building for the restaurant hoping to make it easy to spot from the road. Thought untrained as an architect, he came up with a desing that was simple, memorable, and archetypal. On two sides of the roof he put golden arches, lit by neon at night, that from a distance formed the letter M. The building effortlessly fused advertising with architecture and spawned one of the most famous corporate logos in the world. The Speedee Service System, however, got off to a rocky start. Customers pulles up to the restaurant and honked their horns, wondering what had happened to the carhops, still expecting to be served. People were not yet accustomed to waiting in line and getting their own food. Within a few weeks, however, the new system gained acceptance, as word spread abouth the low prices and good hamburgers. The McDonalds now aimed for a much broader clientele. They employed only young men, convinced that female workers would attract teenage boys to the restaurant and drive away other customers. Families soon lined up to eat at McDonald's. Company historian John F. Love explained the lasting signifiance of McDonald's new self-service system : " Working-class families could finally afford to feed their kids restaurant food. " 3) Explain in your own words what the last two lines mean.

Bonjour, c'est pour un DM de mathématiques URGENT. f et g sont deux fonctions polynomes du second dégré. Voici leurs courbes représentatives Cf (bleu) et Cg(rouge) dans un repère orthonormé. 1. Déterminer l'expression de f(x) et de g(x). (J'AI REUSSI) J'ai besoin de vous pour la question 2. 2. A chaque nombre réel x avec 1 ≤ x ≤ 2, on associe les points M de Cf et N de Cg de même abscisses x. a) Exprimer la distance MN en fonction de x. b)Pour quelle valeur de x, cette distance est-elle maximale? Merci!
