The "nine dots" puzzle. The puzzle asks to link all nine dots using four straight lines or fewer, without lifting the pen. The nine dots puzzle is a mathematical puzzle whose task is to connect nine squarely arranged points with a pen by four (or fewer) straight lines without lifting the pen or retracing any lines.
The point system is a common way of identifying the location of contacts relative to the heading of a ship. It is a form of relative bearing. The point system uses 32 evenly spaced imaginary points that circle the ship starting at the forward bow. Individual points sit at intervals of 11.25°, similar to compass bearings. [1]
The form comes with two worksheets, one to calculate exemptions, and another to calculate the effects of other income (second job, spouse's job). The bottom number in each worksheet is used to fill out two if the lines in the main W4 form. The main form is filed with the employer, and the worksheets are discarded or held by the employee.
A points system for rank in the race and another point system for points based on the length of the race and the distance covered by the driver. For Example: The winner of the Daytona 500 in 1972 received a total of 350 points, 100 points for first place and an additional 250 points (1.25 points per lap * 200 laps) for race distance completed.
Low-point system is a point system in the Racing Rules of Sailing where all the boats in each race of the series score the same number of points as they finish in the race, so that the first boat to cross the finish line gets one point, the second two points. [1]
Direction determination refers to the ways in which a cardinal direction or compass point can be determined in navigation and wayfinding.The most direct method is using a compass (magnetic compass or gyrocompass), but indirect methods exist, based on the Sun path (unaided or by using a watch or sundial), the stars, and satellite navigation.
If an orthocentric system of four points A, B, C, H is given, then the four triangles formed by any combination of three distinct points of that system all share the same nine-point circle. This is a consequence of symmetry: the sides of one triangle adjacent to a vertex that is an orthocenter to another triangle are segments from that second ...
In jurisdictions which use a point system, the police or licensing authorities maintain a record of the demerit points accumulated by each driver. Traffic offenses, such as speeding or disobeying traffic signals, are each assigned a certain number of points, and when a driver is determined to be guilty of a particular offence, the corresponding number of points are added to the driver's total.
