Quelques formules utiles pour la question 3 :

Volume d'une boule : 4/3*Pi*rayon^3

Volume d'un cylindre : Pi*Rayon^2*hauteur

Diamètre = 2*Rayon

Ok et bien je regarde...

Pour l'exo 2.

1 premier cas ou OH=1.5 cm

L'idee est de trouver HM apres la representation du triangle se fait toute seule, celui-ci etant droit en H.

En utilisant Pythagore:

OH^2+HM^2 = OM^2=16

2 second cas ou l'angle HOM vaut 45 degree.

Dans ce cas le triangle est isocele en O et rectangle en O, toujours en utilisant Pythagore et le fait que OH = HM

2*HM^2 = 16

Donc ayant OH et HM dans les deux cas la representation du triangle suit sans probleme.

et le 4 , il est à faire le 4 ? ;)

indication: en utilisant le théorème de Thalès, on montre que le rayon de la base au niveau de la vanille vaut les 2/3 du rayon de la base du cone entier.

enfin, vu l'heure et vu que c'est pour demain, ça m'etonnerait qu'il en fasse bonne usage. :dd:

mais tu as raison par ailleurs

et d'ailleurs, c'est une grosse partie du plaisir des maths, de chercher et de trouver une solution.

Bon j'ai hésité a le faire, mais bon, voila ma présentation de demain, en anglais... Rigolez pas, je suis nul en anglais...

Year 1930. A gunfire shatters the still of the french campaigns: the last wolf has just been shot down. Man got rid of an embarrassing animal because it was socially advanced and had always resisted the human domination. 60 years later, in 1993, the wolf's return is officialized in France, and immediately voices start rising. But why does a simple animal unchain so many passions ?

I) Historical of its return

Contrary to rumors launched by hunters and shepherds, wolves haven't been reintroduced, but came back themselves from Italy, where more than 500 wolves live. The studies carried out in this country shows that the wolf have gradually recolonized the north of Italy since 1974, until it’s settled in nearness of Cunéo (as know under the name of Coni), near French border in 1991. It is during this same year that indices let believe in its presence in France.

November, the fifth nineteen ninety-two (1992), 2 wolves are seen in “Vésubie-Tinée” by 4 Mercantour national park guards during the counting of the chamois. A pack is now setting there which currently counts 6 to 8 wolves.

Then wolves settle in "Vésubie-Roya" in 1994. 5 to 6 wolves live there today.

The "Haute Linnée" is occupied since 1996, like in "High-Roya", this last pack living at Italy en French border.

More recently, a pack has won the queyras.

Since, individuals were located in “Maurienne”, “Isère”, “Dévoluy”, or in “Alpes de Haute Provence”, in “Savoie” and in “vercors”.

Several factors contributed to this return :

significant forest cover (especially since the rural migration and the abandonment of many cultures and pastures areas),

mountainous area with low density of population,

presence of many wild ongulés...

But this return doesn't come without problems.

II) The case of the shepherds and the breeders

From the official announcement of the presence of the wolf in France, hunters, breeders and shepherds shouted at wolf. For them, pastoralism and presence of wolf are absolutely incompatible, they are according to say : "it’s the wolf, or us". For the shepherds, the wolf is a predator, therefore it attacks the cattle, therefore it doesn’t have its place in mountain and must be consequently exterminated.

And it’s true, the wolf is the cause of attacks on the flocks. In 2005, 3660 heads of cattle were compensated : either because the death of the mutton is directly attributable to the wolf, or because several animals taking fear jump into space or, and that is a big problem, attacks of strays dogs were interpreted like attacks of wolves. This last point is extremely important, because in 2001, the strays dogs caused the death of 20.000 animals on the same zone of presence of the wolf. If in more, we take the diseases into account, the wolf is at the origin of the death only from 1 at 2% of the sheep in France.

Moreover, we can ask a simple question : how make the breeders in Italy, where live more than 500 wolves, and more in still the Spanish breeders who be next to 2000 at 2500 wolves when the France counts only hardly one hundred individuals... Why countries which count more wolves have less problems ?

The main explanation is due to the way that in Spain and in Italy, the shepherds cohabited from time immemorial with the wolf and consequently have learned how to live with. Moreover, they developed methods of protection of the herds which allow to very appreciably reduce the number of attacks. Among these methods, the most current consist in keep watch on the herds by specifically drawn up dogs. In these two countries, in some exceptions near, 100% of the animals are under such protection when in France, this figure is lower than 50%. That may be added than Italian and Spanish shepherds consider the few residual attacks to be integral part of the craft.

Besides that, the compensations in the event of wolf attacks are biggest than those versed are given when it’s a wandering dog. And for the case of the hunters, they protest arguing that wolf hunts chamois and others ongulés, reducing by that even the hunting quotas and thus their trophies.

III) What the law says

Now, if we are taking an interest in the applicable laws, we’ll see that it is protected on several levels. Firstly, on the national level, by an interministerial decree signed on October 10, 1996. This text modifies an older decree of 1981. Then Europe intervenes, through directive of 1992 where wolf is recognized like a "Community interest animal species".

Lastly, remind us that France is signatory of the Bern convention of 1979. The wolf appears like a strictly protected species.

In all cases, exemptions exist. So, if the wolf causes significant damage with the breeding, a demolition is possible if there isn’t cast doubt on the viability of the wolf population which is present.

Conclusion

The return of the wolf in France is a reality and it recovers little by little its territory of which it had been exterminated. And at the same time recurred fierce. In one part, the pro-wolf, and in second, the anti-wolf. According to a SOFRES survey of 1995, 80% of the population are in it favour.

Nature reasserts itself. Have been right to again deprive it ?

spirit-> remplace "the human domination" par "man domination" (ligne 2) c + mieux

"wolves haven't been reintroduced,"->wolves weren't reintroduced (y a plus de lien avec le présent, ils ont été réintroduits, c'est fini, donc prétérit)

"where more than 500 wolves live"->where more than 500 of them live (répétition)

"The studies carried out in this country shows"->The studies carried out in this country show (the studies n'est pas 3ème personne du singulier, donc pas de s au verbe)

"that the wolf have"-> that wolf has (on parle ici du loup en général, et 3ème personne du singulier donc has)

"until it’s settled in nearness of Cunéo"->until it settled near Cunéo

"as know under the name of Coni"->also known as Coni

"near French border in 1991"->near the french boundary (LA frontière française, c'est particulier)

"indices let believe in its presence in France."->indices make believe in its presence

November, the fifth nineteen ninety-two (1992)-> ca c'est ce que tu dois dire, pas écrire :transpi:

C'est quoi le comptage du/des chamois ? :yes:

A pack is now setting there which currently counts 6 to 8 wolves.-> :francais: (c'est quoi pack ?)

Then wolves settle in "Vésubie-Roya" in 1994. 5 to 6 wolves live there today.-> si tu parles des meme loups que précedemment, c'est "these wolves". Et "5 to 6 wolves still live there"

The "Haute Linnée" is occupied since 1996, like in "High-Roya", this last pack living at Italy en French border. ->has been occupied (present perfect avec since). Comprends pas la fin.

a pack has won the queyras. -> a pack won (plus de lien avec le présent, donc prétérit)

From the official announcement->because of

pastoralism and presence->the pastoralism and the presence

they are according to say ->they agreed to say

For the shepherds->for shepherds

the wolf is a predator, therefore it attacks the cattle, therefore it doesn’t have its place in mountain and must be consequently exterminated.->the wolf is a predator: it attacks animals (cattle c'est bétail), therefore... et vire consequently, ca sert pas à grand chose (enfin ca c'est toi qui voit)

And it’s true, the wolf->and it's true, wolf

either because the death of the mutton is directly attributable to the wolf, or because several animals taking fear jump into space or, and that is a big problem, attacks of strays dogs were interpreted like attacks of wolves.

->mutton c'est la viande de mouton, un mouton c'est sheep. Remplace attributable par linked, the wolf par wolves, et enfin "or because several animals, frightened, jump from the mountain (rien trouvé d'autre mais c mieux :chinois: ) et "interpreted like" par "interpreted as".

the strays dogs caused the death of 20.000 animals on the same zone of presence of the wolf-> quand c'est général, pas de the ! caused par were responsible of, ca me semble mieux (a toi de voir ça). the wolf par wolves.

If in more, we take the diseases into account, the wolf is at the origin of the death only from 1 at 2% of the sheep in France. -> if in more par and if tout court ca passe :smack: (y a mieux aussi mais ca va). Toujours the wolf par wolves (et on n'oublie pas d'accorder le verbe au pluriel non plus). Are responsible of only 1 to 2% of the sheeps' death in France.

how make the breeders in Italy etc. ->how do italian and spanish breeders do with respectively 500 and 2500-3000 wolves living in their countries, whereas only a hundred in France ?

Why countries which count more wolves have less problems ?->remplace which par that

J'ai pas tout lu c'est long :transpi:
