Las llantas de un automóvil pequeño tiene una medida de 14 pulgadas de diámetro.Realiza la gráfica de una de las llantas colocan

LiRa [457]

Answer:

Invitamos cordial a revisar la imagen adjunta abajo para mayor detalle sobre la gráfica de las llantas.

La forma general de la circunferencia de la llanta está representada por $x^{2}+y^{2}-49 = 0$ .

Step-by-step explanation:

A continuación, anexamos una representación de las llantas del automóvil como una circunferencia centrada en el origen y con un diámetro de 14 pulgadas, es decir, un radio de 7 pulgadas.

La ecuación estándar de la circunferencia centrada en un punto dado y con un radio determinado está definida por:

$(x-h)^{2}+(y-k)^{2} =r^{2}$ (1)

Donde:

$h$ , $k$ - Coordenadas del centro de la circunferencia, medidas en pulgadas.

$r$ - Radio de la circunferencia, medido en pulgadas.

Si conocemos que $h = 0\,in$ , $k = 0\,in$ y $r = 7\,in$ , entonces la ecuación estándar que representa a la circunferencia de la llanta es:

$x^{2}+y^{2} = 49$

Ahora, la ecuación general de la circunferencia centrada en el origen satisface la siguiente expresión:

$A\cdot x^{2}+A\cdot y^{2}+B = 0$ (2)

Donde $A$ , $B$ son los coeficientes de forma de la circunferencia.

Entonces, la forma general de la circunferencia de la llanta está representada por la siguiente expresión:

$x^{2}+y^{2}-49 = 0$

A group of students are asked to evaluate their teacher mid-quarter

Umnica [9.8K]

Answer: perceived lack of anonymity

Step-by-step explanation:

The source of bias that occurs when a group of students are asked to evaluate their teacher mid-quarter is a perceived lack of anonymity.

Perceived lack of anonymity occurs when the responder is afraid that if he or she gives an honest answer, it can end up affecting them negatively.

In this case, the students may be afraid that giving an honest opinion on the teacher will affect them.

Which technique is most appropriate to use to solve each equation? Drag the name of the technique into the box to match each equ

faltersainse [42]

(x + 3) (x + 2) = 0
To solve it, the most appropriate technique is:
1.) zero product property
The solutions are:
(x + 3) = 0
x = -3
(x + 2) = 0
x = -2

x² + 6 = 31
To solve it, the most appropriate technique is:
2.) square root property
x² = 31-6
x² = 25
x = +/- root (25)
x = +/- 5
The solutions are:
x = 5
x = -5
