Erik's disabled sailboat is floating stationary 3 miles east and 2 miles north of kingston. a ferry leaves kingston heading toward edmonds at 9 mph. edmonds is 6 miles due east of kingston. after 20 minutes, the ferry turns, heading due south. ballard is 8 miles south and 1 mile west of edmonds. impose coordinates with ballard as the origin. (let one unit equal one mile.) (a) find the equations for the lines along which the ferry is moving. eastward ? southward x=−2 correct: your answer is correct. (b) the sailboat has a radar scope that will detect any object within 3 miles of the sailboat. looking down from above, as in the picture, the radar region looks like a circular disc. the boundary is the "edge" or circle around this disc, the interior is the inside of the disc, and the exterior is everything outside of the disc (i. e., outside of the circle). give a mathematical description of the boundary, interior, and exterior of the radar zone. (express your answers as equations and/or inequalities using the variables x and y.) boundary 9=(x−(−2))2+(y−10)2 correct: your answer is correct. interior ? exterior ? (c) when does the ferry enter the radar zone? (round your answer to one decimal place.) (d) where does the ferry exit the radar zone? (round your answers to one decimal place as needed.) (x, y) = −2,7 correct: your answer is correct. when does the ferry exit the radar zone? (round your answer to one decimal place.) (e) how long does the ferry spend inside the radar zone? (round your answer to one decimal place.)

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.
