Consider the plate bounded by y2 = 8x and x = 2 with density 8=2-x. 1. Sketch a graph of the plate. Shade in the region and number the axes so that the important points on the plate can be read from the graph. 2. Express the mass of the plate as a double integral and evaluate to find the mass. 3. Express the x-coordinate of the center of mass of the plate as a double integral and evaluate to find the value of x. As a side note, by the symmetry of the plate and density, the y-coordinate of the center of mass y = 0. It might be good practice to confirm this though.

Transcribed Image Text:Consider the plate bounded by y² = 8x and x = 2 with density 8 = 2 - x.
1. Sketch a graph of the plate. Shade in the region and number the axes so that the important
points on the plate can be read from the graph.
2. Express the mass of the plate as a double integral and evaluate to find the mass.
3. Express the x-coordinate of the center of mass of the plate as a double integral and
evaluate to find the value of .
As a side note, by the symmetry of the plate and density, the y-coordinate of the center of
mass y = 0. It might be good practice to confirm this though.
