[1] The stalagmometric method (Ancient Greek: στάλαγμα, romanized: stálagma, lit. 'drop') is one of the most common methods for measuring surface tension . The principle is to measure the weight of drops of a fluid of interest falling from a capillary glass tube , and thereby calculate the surface tension of the fluid.
Many mathematical problems have been stated but not yet solved. These problems come from many areas of mathematics, such as theoretical physics, computer science, algebra, analysis, combinatorics, algebraic, differential, discrete and Euclidean geometries, graph theory, group theory, model theory, number theory, set theory, Ramsey theory, dynamical systems, and partial differential equations.
For any integer n, the last decimal digit of n 5 is the same as the last (decimal) digit of n, i.e. ()By the Abel–Ruffini theorem, there is no general algebraic formula (formula expressed in terms of radical expressions) for the solution of polynomial equations containing a fifth power of the unknown as their highest power.
Some quintic equations can be solved in terms of radicals. These include the quintic equations defined by a polynomial that is reducible, such as x 5 − x 4 − x + 1 = (x 2 + 1)(x + 1)(x − 1) 2. For example, it has been shown [1] that =
The FOIL method is a special case of a more general method for multiplying algebraic expressions using the distributive law. The word FOIL was originally intended solely as a mnemonic for high-school students learning algebra. The term appears in William Betz's 1929 text Algebra for Today, where he states: [2]
The Federal Reserve announced a cut to its benchmark interest rates yesterday, dropping the Fed rate by 25 basis points to a range of 4.50% to 4.75% — the second time its lowered rates since ...
Mitchell finished with 36 points and eight rebounds, and he shot 7-of-16 from behind the arc. Darius Garland added 17 points and five assists, and Mobley finished with 15 points and 11 rebounds.
The car went from 60 to 100 mph in 3.08 seconds before reaching 100 to 150 mph in an additional 2.97 seconds, a video posted to his Instagram showed. “It’s just a BMW,” the post was captioned.
