a. Nombre d'habitants de San Francisco
I. Étude de l'évolution de la population de San Francisco
On souhaite modéliser l'évolution de la population
de San Francisco de 2004 a 2018. On utilise pour cela
un modèle à croissance linéaire. On modélise l'effectif
de cette population à la date 2004+n par une suite U.
La population de San Francisco s'élevait en 2004 à environ
781000 habitants et en 2018 à 383 000 habitants.
FQUESTIONS
9. Déterminer la nature de la suite (U(n)), ne [0;14]
dans ce modèle.
2. Donner la valeur de U(O). Calculer la valeur de n pour
laquelle U(n) = 883000.
3. On noter le nombre de nouveaux habitants qui vivent
à San Francisco chaque année. Déterminer le lien
entre U(n+1) et Uin); entre U(n) et U(O).
4. À l'aide de la question précédente et des données
de l'énoncé, déterminer r à l'unité près.
5. Expliquer ce que renvoie la fonction python suivante
en fonction du paramètre n, entier naturel :
def SF(n):
return 7810007286'n
