Partie A: Évaluation des ressources (15,5points) Exercice 1: ( 3,5 points) Le plan complexe \( P \) est muni d'un repère orthonormé direct \( (O ; \vec{u} ; \vec{v}) \). A et \( B \) sont des points du plan d'affixes respectives \( i \) et \( -2+i . F \) est l'application de \( P-\{A\} \) vers \( P \) qui, à tout point \( M(z) \) associe le point \( M^{\prime}\left(z^{\prime}\right) \) tel que \( z^{\prime}=i\left(\frac{z+2-i}{z-i}\right) \). Pour tout entier naturel \( n \), on désigne par \( C_{n} \) le point d'affixe \( (\sqrt{3}-i)^{n} \). On considère dans \( \mathbb{C} \) l'équation \( (E): z^{2} \cos ^{2} \alpha-2 z \sin 2 \alpha+1=0 \) où \( \left.\alpha \in\right] 0 ; \frac{\pi}{2}[ \). 1) Pour quelles valeurs de \( n \) les points \( C_{n} \) appartiennent-ils à l'axe des réels ? 2) Déterminent \( n \) pour que les points \( C_{n} \) appartiennent à la première bissectrice. \( 0,75 p t \) 3) Déterminer l'ensemble des points invariants par \( F \). 0,5pt 4) Déterminer les parties réelle et imaginaire de \( z^{\prime} \) 0,5pt 5) Résoudre dans \( \mathbb{C} \), l'équation \( (E) \). \( 1 p t \) 0,75pt

3) What type of graph should be made for the experiment in Model 1? * 1 point Scatterplot Bar graph Pie chart 4) What is the relationship between the number of paper clips and distance * 1 point that the paper airplane traveled in Model 1? As the number of paperclips increases, the distance decreases. As the number of paperclips decreases, the distance increases. As the number of paperclips increases, the distance increases.
