Use the shell method to find the volume of the solid generated by revolving the region bound by \( y=2 x, y=0, x=3 \) about the following lines. \( \begin{array}{lll}\text { a. The } y \text {-axis } & \text { b. The line } x=4 & \text { c. The line } x=-9 \\ \text { d. The } x \text {-axis } & \text { f. The line } y=7 & \text { line } y=-4\end{array} \) a. The volume of the given solid is \( \square \) cubic units. (Type an exact answer in terms of \( \pi \).)

\begin{tabular}{l}\( \begin{array}{ll}\text { 8) }-9+5-1-6+1=13 & \text { d) }-41+71-66+17= \\ \text { b) }-12+4-16+48-3=2 \mid & \text { e) } 35-12+34-8+71= \\ \text { c) }-52+62-32-12=-34 & \text { () }-112+100-26-102= \\ & \text { SUPRESION DE PARÉNTESIS }\end{array} \) \\ \hline\end{tabular}

MLA uses what type of spacing? a. Single b. Triple c. None d. Double

22 July 2014 was a Tuesday. 9 August was \( \begin{array}{llll}\text { A } & \text { Thursday } & \text { B } & \text { Friday } \\ \text { C } & \text { Saturday } & \text { D } & \text { Sunday }\end{array} \)

Un quadrato è equivalente ai \( 9 / 4 \mathrm{di} \) un al- tro quadrato avente il lato lungo 14 cm . Calcola il perimetro dei due quadrati. [ \( 5 \mathbf{6 6} \mathbf{~ c m} ; \mathbf{8 4} \mathbf{~ c m} \) ]
