Find a line that lies entirely in the set defined by the equation x2 + y2 − z2 = 1.

Mathematics

Response:

x=1\,,\,y=t\,,\,z=t

Step-by-step explanation:

A line is defined as a one-dimensional entity that lacks thickness and stretches infinitely in both directions.

A line segment contains two endpoints, while a ray consists of a single endpoint.

The equation given is x^2+y^2-z^2=1.

Objective: to identify a line completely within the set designated by this equation.

Solution:

Consider x=1\,,\,y=t\,,\,z=t.

Verification:

L.H.S=1^2+t^2-t^2=1+0=1=R.H.S.

Thus, x=1\,,\,y=t\,,\,z=t fulfills the criteria of the given equation.

A pair of events are observed to have coordinates (0s,0m) and (50.0s,9.00×109m) in a frame s. what is the proper time interval δ
zzz [12365]
To determine the time interval δt, we must subtract the starting time from the ending time. In this scenario, the first value in the coordinates signifies time:

δt=50 - 0
δt= 50s

The time interval is 50s.

Write the expanded form of h(3k-12.4)
babunello [11817]

Answer: 3hk - 12.4h

Step-by-step explanation:

h(3k-12.4)

h multiplied by 3k results in 3hk, and h multiplied by 12.4 gives -12.4h.

So, the outcome is 3hk - 12.4h

E saca una bola de billar al azar de una caja que contiene 15 bolas de billar numeradas del 1 al 15 y se registra el número obte
Zina [12379]

Respuesta:

P = 2/7 = 0.2857 o 28.57%

Explicación paso a paso:

En primer lugar, sabemos que hay 15 bolas y necesitamos identificar cuáles son pares y superiores a 10.

Por lo tanto, debemos calcular inicialmente la probabilidad de que el número obtenido sea par.

Los números pares son 2, 4, 6, 8, 10, 12, 14

Contamos 7 números de 15 ---> P(B) = 7/15

De esos números, solo dos son mayores a 10, que son 12 y 14, así que: P(A|B) = 2/15

Para encontrar la probabilidad de obtener un número par mayor que 10:

P(A/B) = P(A|B) / P(B)

P(A/B) = 2/15 / 7/15 = 2/7 = 0.2857

Para calcular el porcentaje: 0.2857 * 100 = 28.57%.
