Para calcular la ecuación de una circunferencia, necesitamos determinar su centro y su radio.

Paso 1: Encontrar el centro de la circunferencia
El centro de una circunferencia se encuentra en el punto medio de su diámetro. En este caso, los extremos del diámetro son (-5, -4) y (3, 6).

La fórmula para encontrar el punto medio de un segmento de línea con extremos (x1, y1) y (x2, y2) es:

(\frac{x1+x2}{2}, \frac{y1+y2}{2})

Aplicando la fórmula, encontramos que el centro de la circunferencia es:

(-5, -4) + (3, 6) / 2 = (-1, 1)

Paso 2: Encontrar el radio de la circunferencia
El radio de una circunferencia se puede encontrar calculando la distancia entre cualquiera de sus extremos del diámetro y el centro. En este caso, podemos usar la fórmula de distancia entre dos puntos:

d = \sqrt{{(x2-x1)^2 + (y2-y1)^2}}

Usando los puntos (-5, -4) y (-1, 1), la distancia es:

d = \sqrt{{(-1-(-5))^2 + (1-(-4))^2}} = \sqrt{{16 + 25}} = \sqrt{{41}}

Paso 3: Escribir la ecuación de la circunferencia
La ecuación de una circunferencia con centro (h, k) y radio r es:

(x-h)^2 + (y-k)^2 = r^2

En este caso, el centro es (-1, 1) y el radio es \sqrt{{41}} :

(x-(-1))^2 + (y-1)^2 = (\sqrt{{41}})^2

Simplificando:

(x+1)^2 + (y-1)^2 = 41

¡Respuesta! La ecuación de la circunferencia es (x+1)^2 + (y-1)^2 = 41

QUESTION l. An investigation has been carried out in a region to know the perception of "citizen insecurity" of its inhabitants. 1,270 people in the region were interviewed, of which 27.1% responded that it was a "serious" problem. Knowing that this opinion was previously held by 25.3% of the population of that region, we want to know if said opinion has changed significantly for a confidence level of 97.2%. Taking this statement into account, the following is requested: a) Critical value of the contrast statistic. b) Solve the hypothesis test and indicate what conclusion we can reach. c) P-value of contrast.

The car with an irresponsible driver starts to brake when it goes through a red light. When passing the traffic light, he does so at a speed of 115 kph in the right lane. Further ahead, 70 meters from the traffic light, a child is crossing the street and falls. If the effect of the car's brakes is equivalent to a deceleration of magnitude 5.7m/s². Is the child hit by the car or not? How far from the traffic light does the car stop?
