The answer is B. 0.75 because that’s what it would be equal to in decimal form.

the sequence {a_n} is defined by a_1= 1 and a_(n+1) = 1/2( a_n+ (4/a_n) ) for >=1. Assuming that {a_n} converges, find its li
katen-ka-za [31]

a_{n+1}=\dfrac{a_n+\frac4{a_n}}2

Assuming convergence of the sequence, we have a_n\to L for some limit L as n\to\infty. This also means a_{n+1}\to L. So in the above equation, we can substitute and solve for L:

L=\dfrac{L+\frac4L}2

\implies2L^2=L^2+4

\implies L^2=4\implies L=\pm2

The limit can only be one of these values; otherwise, the sequence would be divergent. To decide which one is correct, we can observe that the sequence is strictly positive. So L=2.

Que son lo numeros racionales​
otez555 [7]

Answer:

Un número racional es un número que puede expresarse como una fracción p / q donde p y q son enteros y q! = 0. Se dice que un número racional p / q tiene numerador p y denominador q. Los números que no son racionales se llaman números irracionales. La línea real consiste en la unión de los números racionales e irracionales. El conjunto de números racionales es de medida cero en la línea real, por lo que es "pequeño" en comparación con los irracionales y el continuo.

El conjunto de todos los números racionales se denomina "racionales" y forma un campo que se denota como Q. Aquí, el símbolo Q deriva de la palabra alemana Cociente, que se puede traducir como "cociente", y apareció por primera vez en Bourbaki. Algèbre (reimpreso como Bourbaki 1998, p. 671).

Cualquier número racional es trivialmente también un número algebraico.

Los ejemplos de números racionales incluyen -7, 0, 1, 1/2, 22/7, 12345/67, y así sucesivamente. Las secuencias de Farey proporcionan una forma de enumerar sistemáticamente todos los números racionales.

El conjunto de números racionales se denota Racionales en Wolfram Language, y se puede probar un número x para ver si es racional usando el comando Elemento [x, Racionales].

Las operaciones algebraicas elementales para combinar números racionales son exactamente las mismas que para combinar fracciones.

Siempre es posible encontrar otro número racional entre dos miembros del conjunto de racionales. Por lo tanto, más bien contra intuitivamente, los números racionales son un conjunto continuo, pero al mismo tiempo contables.

Step-by-step explanation:

Lo siento, esto es demasiado largo. Explico mucho las cosas.
