Encuentre el área \( S \) de la superficie que se forma al girar la gráfica de \( y=\sqrt{x} \) sobre el intervalo \( [1,4] \), alrededor del eje \( x \).

2) \( 3+[-20+(-16+5-12)-(14-7+9)+(57-2-18)] \)

73. Resistores Tres resistores de 100,200 y 600 ohms se conectan en paralelo. Determina la resistencia total del circuito. Uti- liza la fórmula \( \frac{1}{R_{T}}=\frac{1}{R_{1}}+\frac{1}{R_{2}}+\frac{1}{R_{3}} \).

How can prosecutors most directly influence law enforcement activity? Through their adherence to ethical standards Through their screening function Through their promotion of financial accountability Through their role as litigators

Find all solutions of the equation in the interval \( [0,2 \pi) \). \[ (\csc \theta-\sqrt{2})(\sec \theta+\sqrt{2})=0 \] Write your answer in radians in terms of \( \pi \). If there is more than one solution, separate them with commas. \( \theta=\square \)
