Porqué el valor del coeficiente de la variable al cuadrado de una función cuadratica no puede ser cero?

Answer:

Ver respuesta abajo

Step-by-step explanation:

Una ecuación cuadrática es una ecuación que tiene la siguiente forma:

ax² + bx + c = 0

Donde:

a, b y c: coeficientes numéricos que acompañan a la incógnita.

Ahora bien, una función cuadrática es basicamente la misma ecuación cuadrática pero representada graficamente en un plano cartesiano.

Para que una ecuación o función sea cuadrática es absolutamente necesario y obligatorio que su expresión en forma de ecuación tenga el elemento "ax²", pues el "cuadrado" que es el exponente 2 que eleva la incógnita es lo que le da la característica de ecuación o función cuadrática.

Si el coeficiente que acompaña al x², es decir, el valor de a es cero, automaticamente pierde la condición de ser una función o ecuación cuadrática pues dicho término se hace cero su valor. En otras palabras, si x es un número cualquiera y está representado como incógnita, ¿qué sucede cuando multiplicas cualquier número por cero?, en este caso, el resultado es igual a cero:

Ejemplo:

0x² = 0 * x² = 0.

Por tanto, si el término cuadrático se hace cero, ya pierde la condición de cuadraticidad, y su gráfico no sería de forma parabólica, solo quedaría los términos bx + c, pero eso ya pertenece a una ecuación lineal o función afín.

Espero esto te sirva.

olasank [31]

Answer:

C(x) = 0.1x+23000

Step-by-step explanation:

Given that a company sells doughnuts. They incur a fixed cost of $23000 for rent, insurance, and other expenses. It costs $0.1 to produce each doughnut. The company sells each doughnut for $0.2.

Let X be the no of units produced

Then we have variable cost = 0.1x

Fixed cost = 23000 (irrespective of value of x)

Total cost

C(x) = 0.1x+23000

where C represents the total cost and x no of units produced.

Revenue function would be

R(x) = 0.2x assuming all doughnuts are sold.

Profit function would be

P(X) = 0.1x-23000

alexandr402 [8]

Answer: The amount of money each student raised = $2

Step-by-step explanation:

Given : In charity

Total students participate= 456

Total collection = $912

Each student brought in the same amount of money , then the amount each student raised = \dfrac{\text{Total collection }}{\text{Total students}}

=\$\dfrac{912}{456}\\\\=\$2

Hence, the amount of money each student raised is $2.

Step-by-step explanation:

Homesick is author Jean Fritz's story of her childhood growing up in China in a town called Hankow. While Jean adopts a first-person perspective and includes mostly real-life details from her life, some parts of Homesick are fictionalized in order to add dramatic interest.

Answer:

  • k = 6.26

Step-by-step explanation:

Find the midpoint of each frequency range, multiply that number by the frequency, sum up and divide by the total frequency.

This will give the mean number.

<u>The mean is:</u>

  • [17*( 3 + 3.5)/2 + 21*(3.5 + k)/2 + 33*(k + 4)/2 + 54*(4 + 4.5)/2 + 15*(4.5 + 6)/2]/140 = 4.09
  • 55.25 + 10.5k + 36.75 + 16.5k + 66 + 229.5 + 78.75 = 140*4.09
  • 17k + 466.25 = 572.6
  • 17k = 572.6 - 466.25
  • 17k = 106.35
  • k = 106.35/17
  • k = 6.26

Note, I expected the value of k between 3.5 and 4. This is a bit of illogical outcome.
