To find the locus of point \( P(x, y, z) \) such that \( 3PA = 2PB \), where \( A(-2, 2, 3) \) and \( B(13, -3, 13) \), we can follow these steps: ### Step 1: Write the distance formulas The distance \( PA \) from point \( P \) to point \( A \) is given by: \[ PA = \sqrt{(x + 2)^2 + (y - 2)^2 + (z - 3)^2} \] The distance \( PB \) from point \( P \) to point \( B \) is given by: ...
