QuestionAnswer
direct variation A linear function defined by an equation of the form y = kx, k does not equal 0. You say that y is directly proportional to x.
rise the vertical change between two points on a line.
diameter a segment that joins two points of the circumference with the center of the circle.
arc Part of a circle. Any angle
dimensional analysis A problem solving strategy where you cancel units of measurement as if they are numbers.
variation constant The linear function defined by an equation of the form y = kx, k does not equal 0. You say that y is directly proportions to x.
run The horizontal change between two points on a line.
circumference The perimeter of a circle. The distance around the circle.
arc length The measurement of an arc.
sector The region formed by a centrai angle and its arc is a sector.
variation The nonzero constant k in a direct variation defined by y = kx.
slope The measure of the steepness of a line given by the ratio of rise to run for any two points on the line.
pi The ratio of circumference to diameter is a constant.
general form for direct variation ratio of quantites = variation constant
tangent ratio The ratio compares the two legs of a right triangle. leg opposite / leg adjacent.
conversion factor A conversion factor is a ratio of two equal(or approximately equal) quantites that are measured in different units.
