Una baita ha 16 finestre. Su ciascuna finestra ci sono due piante di geranio, che costano \( 3 \in \) f'una. Quante costa mettere ig gerania tutte le finestre?

Find \( \sin 2 x, \cos 2 x \), and \( \tan 2 x \) if \( \sin x=\frac{1}{\sqrt{5}} \) and \( x \) terminates in quadrant II. \( \begin{array}{l}\sin 2 x=\square \\ \cos 2 x=\square\end{array} \)

Question 31 When silver crystallizes, it forms face-centered cubic cells. The unit cell edge is 408.7 pm . Given the density of silver is \( 10.5 \mathrm{~g} / \mathrm{cm} 3 \). Using this information, calculate Avogadro's number. - No text entered -

Calcula el área de la región acatada por las funciones \( f(x)=x+1, g(x)=x^{2} \)

\( y=\left\{\begin{array}{ll}-x & \text { se } x \leq 0 \\ 4 x & \text { se } x>0\end{array}\right. \)
