In a three-dimensional coordinate system, the distance between two points (X1 .y, ,Z, ) and (X2,y2.Z2 ) can be found with the extension of the distance formula shown below. Find the distance between T(1, - 1,3) and V( - 6,6,2). d= ( x 2 - * 1 ) 2 + ( Y2 - >1 ) 2 + ( 22 - 21 ) 2 The distance is (Round to the nearest tenth as needed.)
