A plane is defined by any three points that are in the plane. If a plane contains the points P=(1,0,0), Q=(1,1,1) and R=(2,1,3) find a vector that is orthogonal to the plane. The geometric shape represented by the equation (x4)2+y2+(z+1)2=25 is Sphere with a center of (4,0,1) and radius of 5 units Sphere with a center of (4,0,1) and radius of 25 units Sphere with a center of (4,0,1) and radius of 5 units Sphere with center of (4,0,1) and radius of 5 units The unit vector for the vector a=4,3,0 is: 54,53,0 1,1,0 54,53,1 254,253,0
