Jaclyn estimates the square root of 50 in the following way: 150 -2.25 -205 - 10
(a) Explain why her reasoning is incorrect.

(b) Estimate the square root of 50 to the nearest tenth without using your calculator. Show your work.

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.
