Consider the ellipse 25xsquared plus 4y squared equals 1 in the xy-plane. a. if this ellipse is revolved about the x-axis, what is the equation of the resulting ellipsoid? b. if this ellipse is revolved about the y-axis, what is the equation of the resulting ellipsoid?

Step-by-step explanation:

When the figure is revolved around the x-axis, its extent in the z-direction will match its extent in the y-direction. So, the z-term will have the same coefficient as the y-term. 25x² +4y² +4z² = 1

Similarly, when the figure is revolved around the y-axis, its extent in the z-direction will match its extent in the x-direction. Then the z-term will have the same coefficient as the x-term. 25x² +4y² +25z² = 1

the battle of gettysburg is considered the "high water mark" of the confederacy because it marked the greatest advance of the confederate forces against the union.
