Step-by-step explanation:

Two lines are parallel if they have the same slope.

To find the slope of the line that passes through two points, (x_{1}, y_{1}) and (x_{2}, y_{2}), you can use the following formula:

\frac{y_{2} - y_{1}}{x_{2} - x_{1}}

For the first set of points, (-1, -2) and (4, 4), we can find the slope with the following:

\frac{4 - (-2)}{4 - (1)}

\frac{4 + 2}{4 + 1}

\frac{6}{5}

For the second set of points, (6, 3) and (-1, -3), we can find the slope with the following:

\frac{-3 - 3}{-1 - 6}

\frac{-6}{-7}

\frac{6}{7}

Since the two slopes are \frac{6}{5} and \frac{6}{7}, the two lines are not parallel.

Ostrovityanka [42]
<span>There are 24 who like both rock and country. There are 8 who like all 3 types, and these eight have been counted under the 24. This means that the number who like rock and country but not jazz is 24 - 8 = 16.
We are given a total of 155 who like country. We subtract the 16 who like both rock and country, and are left with 139 people who like country but not rock. (It does not matter whether they like jazz or not).
The probability is 155 out of the total of 500, so 155/500 = 31/100 = 0.31.

Cual es la magnitud de la aceleración angular de una llanta de un automóvil que adquiere una velocidad angular de 350 rad/s en 2
drek231 [11]

Respuesta:

175 rad / s²

Explicación paso a paso:

Dado que :

Velocidad angular final = 350 rad / s

Tiempo empleado = 2 segundos

La aceleración angular, a =?

Recordar ; la aceleración angular es igual a la carga en velocidad angular con el tiempo

(velocidad final - Velocidad inicial) / tiempo empleado

Velocidad inicial = 0 rad / s

Aceleración angular = (350 - 0) / 2 = 350/2

= 175 rad / s²
