1) what is the contour interval of the map?

5.5 Contour Lines and Intervals. A contour line is a line drawn on a topographic map to indicate ground elevation or depression. A contour interval is the vertical distance or difference in elevation between contour lines.

Terminology. An open interval does not include its endpoints, and is indicated with parentheses. For example, (0,1) means greater than 0 and less than 1. ... A closed interval is an interval which includes all its limit points, and is denoted with square brackets.

['Measure distance between two points on a map in cm or mm.', 'Multiply this by the scale of the map and divide by 100 000 if you used centimetres or by 1000 000 if you used millimetres to get kilometres.']

Topographic Maps A topographic map is similar to a physical map in that it shows different physical landscape features. Unlike physical maps, though, this type of map uses contour lines instead of colors to show changes in the landscape.

The set of all real numbers is the only interval that is unbounded at both ends; the empty set (the set containing no elements) is bounded. An interval that has only one real-number endpoint is said to be half-bounded, or more descriptively, left-bounded or right-bounded.

The contour interval is the difference in elevation between adjacent contour lines. The elevation for each contour line is sometimes marked on the line.

tangents are drawn from (4,4) to the circle x^2+y^2-2x-2y-7=0 to meet the circle at A and B the length of the chord AB is. Hey man !! from the equation of the circe above you can find out the centre of the circle.

Answer: A line segment has two endpoints. A line has no end point.

A contour line is a line drawn on a topographic map to indicate ground elevation or depression. A contour interval is the vertical distance or difference in elevation between contour lines. Index contours are bold or thicker lines that appear at every fifth contour line.

5 Elements of any Map. Maps contain lots of information. Most maps will have the five following things: a Title, a Legend, a Grid, a Compass Rose to indicate direction, and a Scale.

Circles, spheres, and segments The center of a circle is the point equidistant from the points on the edge. Similarly the center of a sphere is the point equidistant from the points on the surface, and the center of a line segment is the midpoint of the two ends.

Advantage: The Robinson map projection shows most distances, sizes and shapes accurately. Disadvantage: The Robinson map does have some distortion around the poles and edges.
