Pairs of markings a set distance apart are made on highways so that police can detect drivers exceeding the speed limit. over a fixed? distance, the speed r varies inversely with the time t. in one particular pair of? markings, r is 66 mph when t is 66 seconds. find the speed of a car that travels the given distance in 55 seconds.

Find x to the nearest hundredth place

Which function has the domain x> -11?

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.
