Question
![**Problem Statement**
Find the mass and center of mass of the lamina bounded by the graphs of the equations for the given density.
**Equations and Conditions**
- \( y = \cos\left(\frac{\pi x}{8}\right) \)
- \( y = 0 \)
- \( x = 0 \)
- \( x = 4 \)
- \( \rho = 2ky \)
**Calculations**
- Mass, \( m = \) [Blank for calculation]
- Center of mass, \( (\bar{x}, \bar{y}) = \) \([Blank, Blank]\)
**Explanation**
This problem involves determining the mass and center of mass for a lamina with variable density defined by \(\rho = 2ky\). The shape is bounded by the cosine curve, horizontal line at \(y = 0\), and vertical lines at \(x = 0\) and \(x = 4\).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ffa48f7eb-bce8-4ea0-bf8b-7482c9c56a7c%2F8235fe39-30a8-4bf5-8b4f-b75886d96f0a%2F713w5f8_processed.jpeg&w=3840&q=75)
