[1] [2] as a ratio of one part rise to so many parts run. For example, a slope that has a rise of 5 feet for every 1000 feet of run would have a slope ratio of 1 in 200. (The word "in" is normally used rather than the mathematical ratio notation of "1:200".) This is generally the method used to describe railway grades in Australia and the UK.
Advanced Placement (AP) Music Theory (also known as AP Music or AP Theory) is a course and examination offered in the United States by the College Board as part of the Advanced Placement Program to high school students who wish to earn credit for a college-level music theory course.
Slope illustrated for y = (3/2)x − 1.Click on to enlarge Slope of a line in coordinates system, from f(x) = −12x + 2 to f(x) = 12x + 2. The slope of a line in the plane containing the x and y axes is generally represented by the letter m, [5] and is defined as the change in the y coordinate divided by the corresponding change in the x coordinate, between two distinct points on the line.
Stream gradient (or stream slope) is the grade (or slope) of a stream. It is measured by the ratio of drop in elevation and horizontal distance. [ 1 ] It is a dimensionless quantity , usually expressed in units of meters per kilometer (m/km) or feet per mile (ft/mi); it may also be expressed in percent (%).
Thus, a supply curve with steeper slope (bigger dP/dQ and thus smaller dQ/dP) is less elastic, for given P and Q. Along a linear supply curve such as Q = a + b P the slope is constant (at 1/b) but the elasticity is b(P/Q), so the elasticity rises with greater P both from the direct effect and the increase in Q(P).
The LP (from long playing [2] or long play) is an analog sound storage medium, specifically a phonograph record format characterized by: a speed of 33 + 1 ⁄ 3 rpm; a 12- or 10-inch (30- or 25-cm) diameter; use of the "microgroove" groove specification; and a vinyl (a copolymer of vinyl chloride acetate) composition disk.
The album-equivalent unit, or album equivalent, [1] is a measurement unit in music industry to define the consumption of music that equals the purchase of one album copy. [2] [3] This consumption includes streaming and song downloads in addition to traditional album sales. The album-equivalent unit was introduced in the mid-2010s as an answer ...
A440 (also known as Stuttgart pitch [1]) is the musical pitch corresponding to an audio frequency of 440 Hz, which serves as a tuning standard for the musical note of A above middle C, or A 4 in scientific pitch notation. It is standardized by the International Organization for Standardization as ISO 16.
