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

A psychologist is investigating the levels of test anxiety in various university courses. Anxiety is measured on a scale ranging from 0 to 100, where 0 indicates the complete absence of anxiety and 100 represents an extreme level of anxiety. From the data obtained, it has been discovered that the psychology score is triple that of nursing, and in turn, the latter has a score 10 points lower than the nutrition major. Furthermore, the score in the veterinary degree is 15 points higher than that of nutrition. Finally, if we add the scores of all the races, we will obtain a total of 173 points. Pose the equation that represents the situation described in the previous problem and determine: What is the score that psychology obtained regarding its anxiety level before the exams?

Matilde knows that, when driving her car from her office to her apartment, she spends a normal time of x minutes. In the last week, you have noticed that when driving at 50 mph (miles per hour), you arrive home 4 minutes earlier than normal, and when driving at 40 mph, you arrive home 5 minutes earlier later than normal. If the distance between your office and your apartment is y miles, calculate x + y.
