6. Halle el valor numérico de las sigulentes expresiones de acuerdo a los valores dados a las variables a) \( 5 x^{2}-3 x^{2}+6 x \quad \) para \( x=-1 \)

\( \{ B = \{ ( 2,5 ) , ( 1,2 ) \} \quad B ^ { \prime } = \{ ( 2,1 ) , ( - 1,2 ) \} \)

Question 2: Consider the different approaches to the project taken by both Monica and Jennifer. On which of the Big 5 personality traits do they most differ? Discuss these differences in their personality traits.

vo 1: Aproxima el límite de la función \( f(x)=\frac{x^{3}-49}{x-7} \) cuando \( x \) tiende a 7 . vo 2: Evalúa la derivada de la función \( h(x)=\left(7 x^{2}+4\right)(3 x-6) \) en \( x=-1 \)

Veriflez que la relation : \( \frac{1}{1+(t a n c)^{2}}=(\cos c)^{2} \) est vraie pour l'angle \( c \) de mesure \( 60^{\circ} \) a partir des valeurs de cos \( 60^{\circ} \) et tan \( 60^{\circ} \) détermines ci-dessus. Demontrez que la relation est vraie pour tout angle aigu de mesure c.

Match each of the following expressions with an equivalent expression. (You can use each option once, more than once, or not at all.) \( \begin{array}{ll}-\checkmark \frac{\sin (\theta)}{\csc (\theta)} & \text { a. } \sin ^{2}(\theta) \\ -\vee \tan (\theta) \cdot \cot (\theta) & \text { c. } \cot (\theta) \\ -\checkmark \cos (\theta) \cdot \csc (\theta) & \text { d. } 1 \\ -\checkmark \sec (\theta) \cdot \cos (\theta) & \end{array} \)
