Police know the exact distance that it takes a car to stop at 80, 100, and 120 miles per hour. however at a crash scene, the police find skid marks longer than those left at any known speed. they use a graph to predict the car's speed as approximately 137 miles per hour. predicting a value or quantity beyond a known data range, based on a trend in the data, is a) deduction. b) extrapolation. c) interpolation. d) observation.

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by  mathematical calculations  before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of  uranus  led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to   spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.
