#9. (a) Change to spherical coordinates and evaluate $$\int_{0}^{\frac{1}{\sqrt{2}}} \int_{-\sqrt{\frac{1}{2}-y^2}}^{\sqrt{\frac{1}{2}-y^2}} \int_{\sqrt{x^2+y^2}}^{\sqrt{1-x^2-y^2}} z^2 dz dx dy.$$ (b) Change to cylindrical coordinates and evaluate $$\int_{0}^{1} \int_{-\sqrt{1-y^2}}^{\sqrt{1-y^2}} \int_{x^2}^{1-y^2} z dz dx dy.$$ #10. Use generalized polar/cylindrical coordinates $$x = ar \cos \theta$$, $$y = br \sin \theta$$, $$z = z$$, $$dV = abr dz dr d\theta$$, with suitable a, b, to find the moment $$M_{xy}$$ (about the xy-plane) of the solid below $$z = 46-5x^2-7y^2$$ but above $$z = 10-x^2+2y^2$$, with density $$\rho(x, y, z) = \frac{4}{z}$$.

If the financial markets are at least semi-strong form efficient, then: - An increase in the value of one security should be offset by a decrease in the value of another security. - Stock prices should increase or decrease slowly as new events are analyzed and the information is absorbed by the markets. - Stock prices should remain constant. - Stock prices will only change when an event actually occurs, not at the time the event is anticipated. - Stock prices should only respond to unexpected news and events.
