Note: When dealing with a curve like y² = 8x, it's important to note that here can be negative y-values. In particular, if taking square roots (which is not necessary), be sure to include both positive and negative square roots. 1. Sketch a graph of the plate. Shade in the region and number the axes so hat 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 nass. 3. Express the x-coordinate¹ of the center of mass of the plate as a double ntegral and evaluate to find the value of .

Question
Transcribed Image Text:Consider the plate bounded by y² = 8x and x = 2 with density d = 2 - x.
Note: When dealing with a curve like y² = 8x, it's important to note that
there can be negative y-values. In particular, if taking square roots (which is
not necessary), be sure to include both positive and negative square roots.
1. Sketch a graph of the plate. Shade in the region and number the axes so
