Identify the number that does not belong with the other three. explain your reasoning. 50.1 repeating 1, negative 50 over 2, negative 50.1, square root 50

The number that does not belong with the other three is √50.

Step-by-step explanation:

Consider the provided numbers.

Rational number: A number   is said to be rational, if it is in the form   of p/q. Where p and q are integer and   denominator is not equal to 0. The decimal expansion of rational numbers may terminate or become periodic.

Irrational   number: A number is irrational if it cannot   be expressed be expressed by dividing two   integers. The decimal expansion of   Irrational numbers are neither terminate nor   periodic.

Now consider the number.

50.1 repeating 1 is a rational number as the decimal expansion is periodic.

Negative 50 over 2 can be written as: -50/2

-50/2 is a rational number as it is in the form of p/q.

Negative 50.1 can be written as: -501/10

Thus, -501/10 is a rational number as it is in the form of p/q.

√50 = 7.071067...

The number √50 is not a rational number as the decimal expansion of   number is neither terminate nor   periodic.

Hence, the number √50 is an irrational number.

The number that does not belong with the other three is √50.

la parábola es el lugar

geométrico en el cual los puntos tienen una distancia idéntica, equidistantes,

de un punto denominado foco, f, y una recta denominada directriz

el radio vector de una

parábola es el segmento que existe entre un punto cualquiera y el foco.

por la ecuación se observa

que la parábola abre hacia la derecha, por lo cual podemos usar las siguientes fórmulas

la ecuación ordinaria de la

parábola es y^2 = 4px, donde p es la longitud desde el vértice de la parábola al

foco.

la fórmula de la directriz

es x + p = 0

resolviendo:

y^2-9x = 0

y^2 = 9x

4p = 9, entonces p = 9/4

entonces el foco tendrá la

coordenada f(9/4,0)

la directriz vendrá

expresada por

x + p = 0

x = -p

x = -9/4

el problema indica que la

ordenada es igual a 6, entonces

(6)^2=9x

x = 36/9

x = 4

entonces el punto al cual

hay que obtener la distancia será p(4,6)

calculando se tendrá: pf = 

pf = 6,25 u
