Present value. In economics and finance, present value ( PV ), also known as present discounted value, is the value of an expected income stream determined as of the date of valuation. The present value is usually less than the future value because money has interest -earning potential, a characteristic referred to as the time value of money ...
The azimuth is the angle between the north vector and the star's vector on the horizontal plane. [2] Azimuth is usually measured in degrees (°), in the positive range 0° to 360° or in the signed range -180° to +180°. The concept is used in navigation, astronomy, engineering, mapping, mining, and ballistics .
Money portal. v. t. e. The loan-to-value ( LTV) ratio is a financial term used by lenders to express the ratio of a loan to the value of an asset purchased. In real estate, the term is commonly used by banks and building societies to represent the ratio of the first mortgage line as a percentage of the total appraised value of real property.
The labor theory of value ( LTV) is a theory of value that argues that the exchange value of a good or service is determined by the total amount of "socially necessary labor" required to produce it. The contrasting system is typically known as the subjective theory of value . The LTV is usually associated with Marxian economics, although it ...
The Born–Landé equation is a means of calculating the lattice energy of a crystalline ionic compound. In 1918 [1] Max Born and Alfred Landé proposed that the lattice energy could be derived from the electrostatic potential of the ionic lattice and a repulsive potential energy term. [2] where: r0 = distance between closest cation [ +ve ...
In mathematics, the logarithm is the inverse function to exponentiation. That means that the logarithm of a number x to the base b is the exponent to which b must be raised to produce x. For example, since 1000 = 103, the logarithm base of 1000 is 3, or log10 (1000) = 3.
