AIDEZ MOI SVPPP Urgent !! L'objectif de cet exercice est de déterminer:
s'il existe une position de M pour laquelle l'aire de la
surface colorée est égale à 800 m?.
s'il existe une position de M pour laquelle l'aire colo-
rée est égale à celle du triangle PBN.
On note x la longueur AM et A la fonction, qui à r associe
l'aire du rectangle AMNP.
QUESTIONS :
1. A quel intervalle la variable “X” appartient-elle ? On
note “I” cet intervalle dans la suite.
2. a. On admet que le triangle NP est rectangle isocèle
en P. Exprimer la lonqueur AP en fonction de x.
b. En déduire que l'aire du rectangle APNM est égale
à A(x) = 60x - x2 (forme 1).
c. Justifier que, pour tout réel r E I, on a :
A(x) = 900 - (x-30)2 (forme 2)
3. Résoudre les dux problèmes posés en introduction
en précisant, dans chaque cas, les positions du point M
correspondantes.
4. Justifier que, pour tout rEl, on a A (1) < 900
Préciser la valeur de x pour laquelle A (r) = 900.

Iwill give ! if m∠a=59 and m∠3=81°, what is m∠b? m∠b= _[blank]_°

Apoll is being conducted at a mall nothingto obtain a sample of the population of an entire country. what is the frame for this type of​ sampling? who would be excluded from the survey and how might this affect the results of the​ survey? what is the frame for this type of​ sampling? a. the frame is people who need new clothes. b. the frame is people who shop at the mall. c. the frame is people who like to shop. d. the frame is the entire population of the country. who would be excluded from the survey and how might this affect the results of the​ survey? a. any person that does not need new clothes is excluded. this could result in sampling bias due to undercoverage. b. any person who does not shop at the mall is excluded. this could result in sampling bias due to undercoverage. c. any person who does not shop at the mall is excluded. this could result in nonresponse bias due to people not participating in the poll. d. there is nobody that is being excluded from the survey.

Which of the following domains provide a real value periods
