Convert the system to an augmented matrix Then reduce the system to echelon form and determine if the system is consistent If the system in consistent, then find all solutions Augmented matrix: Echelon form: Is the system consistent? Solution: (x1,x2,x3) =

On traditional maps, earth is represented in a flat plane, or by euclidean geometry. however, a globe is a more accurate model that comes from elliptical geometry.how does a globe represent the fact that there are no parallel lines in elliptical geometry? the equator is not parallel to any other latitudinal lines. the north and south poles are never connected by a geodesic. the geodesics connecting the north and south poles never intersect. the geodesics connecting the north and south poles intersect at both of the poles.
