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

elly's long hair:

a. if the salon only takes cash, then this isn't the problem. it doesn't matter how much she has in her checking account.   she can't get a haircut until she has the cash.

b. if she has overdraft protection, then there's no problem.   she can go ahead and write a check that her account can't cover, then sometime later, pay the bank some outrageous usury for loaning her a few bucks for a few days, but with beautiful hair.

c. if elly has some principles, and doesn't want to write a bad check, then now she has a problem.   her desire for the new hairstyle is in conflict with her honesty and integrity.

d.   if the bank will not process a check she writes, then even if she had a million $$ in her account, she couldn't use any of it.   the amount she has in her account is not the problem.   and if i may suggest, she might as well close her checking account, and put the money where it'll work for her.   it's not doing her a bit of good in a checking account, since she can't write any checks.

justin can't pay the full balance:

a. he can't even handle the credit limit he has now.   under no circumstances should he ask for a higher limit.

b.   he can ask for the grace period to be extended.   but that's no solution, the bank will almost certainly refuse anyway, and there are much better options.   he knew the rules of his credit card when he started using it.

c.   he definitely should pay the interest on the balance, plus as much of the balance as he can cover at the same time.

d.   he definitely should pay the minimum otherwise they could shut down his card.   he should also pay as much more as he possibly can.   he should also remember the awkward situation he's in, stop buying stuff on credit that he can't afford, and avoid adding any more debt.

i'd say that justin's best best option isn't on this list of choices.   what he has to do:   pay as much as he can at least the minimum payment plus as much more as he can and then avoid adding more debt.

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is
