Three-fifths of the beads on Georgia's necklace are silver, and the remaining beads are gold. If she adds an extension that has 4 silver beads and 10 gold beads, then the number of silver beads will be the same as the number of gold beads. What is the total number of beads on Georgia's necklace before she adds the extension?

Determine whether the following statements are true and give an explanation or counterexample. bold a. when using the shell method, the axis of the cylindrical shells is parallel to the axis of revolution. bold b. if a region is revolved about the y-axis, then the shell method must be used. bold c. if a region is revolved about the x-axis, then in principle it is possible to use the disk/washer method and integrate with respect to x or the shell method and integrate with respect to y.

Will give brainliest immeadeately true or false: the origin woud be included in the solution set for the inequality: y< 2x-5

Can someone me with #s 8, 9, and 11. with just one of the three also works. prove using only trig identities.
