14 godz. temu · Step 1/40. Identify the integral to be evaluated: ∫ 9 e 2 x + e 2 x d x. Step 2/40. Recognize that the integrand involves a composite function 2 x + e 2 x. To simplify, we can use substitution. Let: u = 2 x + e 2 x. Step 3/40. Differentiate u with respect to x to find d u : d u d x = 2 + 2 e 2 x d u = ( 2 + 2 e 2 x) d x d u = 2 ( 1 + e 2 x) d ...
14 godz. temu · Properties Form and structure Gallium crystals Most metals are shiny and lustrous, at least when polished, or fractured. Sheets of metal thicker than a few micrometres appear opaque, but gold leaf transmits green light. This is due to the freely moving electrons which reflect light. Although most elemental metals have higher densities than nonmetals, there is a wide variation in their ...
14 godz. temu · The natural logarithm of a number is its logarithm to the base of the mathematical constant e, which is an irrational and transcendental number approximately equal to 2.718 281 828 459. The natural logarithm of x is generally written as ln x, log e x, or sometimes, if the base e is implicit, simply log x. Parentheses are sometimes added for clarity, giving ln(x), log e (x), or log(x).
14 godz. temu · Hubble's law, also known as the Hubble–Lemaître law, is the observation in physical cosmology that galaxies are moving away from Earth at speeds proportional to their distance. In other words, the farther they are, the faster they are moving away from Earth. The velocity of the galaxies has been determined by their redshift, a shift of the light they emit toward the red end of the visible ...
14 godz. temu · In statistics, maximum likelihood estimation (MLE) is a method of estimating the parameters of an assumed probability distribution, given some observed data.This is achieved by maximizing a likelihood function so that, under the assumed statistical model, the observed data is most probable. The point in the parameter space that maximizes the likelihood function is called the maximum likelihood ...
