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.

Annie wants to create a right triangle with side lengths 12 centimeters, 35 centimeters, and
37 centimeters.
Is this possible? Why or why not?
Yes, because 12 + 35 is not equal to 37.
Yes, because 12? + 352 is equal to 372
No, because 12 + 35 is greater than 37.
No, because 12? + 352 is less than 372.
Answer: yes because 12^2+35^2=37^2
Step-by-step explanation:
Roger jarred 15 liters of jam after 2 days. How much jam did Roger jar if he spent 6 days making jam?
Answer: 45 liters
Step-by-step explanation:
If Roger jars 15 liters of jam in 2 days, we can divide to see how much liters of jam Roger can jar in 1 day. We can divide 15 by 2 to find how much jam can be jarred in one day.
15 / 2 = 7.5.
Roger can jar 7.5 liters of jam every day.
Now we can multiply 7.5 by 6 to find how much jam Roger can jar at the end of 6 days.
7.5 x 6 = 45.
Therefore, Roger can jar 45 liters of jam in 6 days.

What is the value of x and y?
Answer:
x = 9 ; y = 18
Step-by-step explanation:
This is a 30° 60° 90° triangle meaning the length of the big leg will be the value of the small leg times √3 and the hypotenuse will be double the length of the small leg.
Answer:
x = 9
y = 18
Step-by-step explanation:
tan(60) = 9 radical 3 / x
x = 9 radical 3 / tan(60)
x = 9
a² + b² = c²
9² + 9radical3² = c²
324 = c²
c = 18
y = 18
What is the area of the trapezoid?
68
54
76
108
Answer:
54
Step-by-step explanation:
So, we know that the area of a Trapezoid is (a + b)/2 * h
A is the base of the ceiling of the trapezoid, B is the floor of the trapezoid, and H stands for the height of the trapezoid. After counting, we now know that A = 6, B = 12, and H = 6. If we plug that into the formula, then we get 18/2 * h, then 9 * h, then 54. So, the answer is 54.

In ΔFGH, the measure of ∠H=90°, HG = 56, FH = 33, and GF = 65. What ratio represents the cosine of ∠G? ASAP PLS
The value of ratio which represents the cosine of ∠G is,
⇒ cos G = 56/65
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
We have to given that;
In ΔFGH,
The measure of ∠H=90°, HG = 56, FH = 33, and GF = 65.
Now, By the formula;
⇒ cos θ = Base / Hypotenuse
Hence, We get;
⇒ cos G = GH / GF
⇒ cos G = 56/65
Thus, The value of ratio which represents the cosine of ∠G is,
⇒ cos G = 56/65

What is the volume of a cube with an edge length
of 2/3 foot?
Answer:
V= 512 inches or, 42.67 feet
Step-by-step explanation:
So a cube has the same length on all sides so you would multiply length times with times area or V = a^3
So, 2/3 foot is equal to 8 inches so you would do V = 8^3 which would get you the answer,

Q2. In a camp food was enough for 400 people for 23 days. If 60 more people joined the camp, find the number of days the food will last?
Q3. Given that y is directly proportional to x and that y= 40 when x= 200, find the value of
(a) y when x= 15
(b) x when y= 8
Q4. If y is inversely proportional to x and that y= 8 when x= 30, find the value of:
(a) the value of y when x= 4
(b) the value of x when y= 360
Answer:
Q2)
We have food for 400 people, and it will last for 23 days.
Then we have an inverse relation, where the number of days decreases as the number of people increases, this means that we have a relationship like:
23 days = K/400 people.
Then we get:
(23 days)*(400 people) = K = 9200 days*people.
Now if we increase the number of people by 60, we get.
people = 460
Then the number of days that this will last is:
D = (9200 days*people)/460 people = 20 days.
The food will last for 20 days.
Q3) We have a proportional relationship (y = k*x) such that y = 40 when x = 200, then we get:
40 = k*200
With this, we can find the value of k
40/200 = k = 0.2
Then the proportional relationship is:
y = 0.2*x
a) We need to replace x by 15.
y = 0.2*15 = 3
y = 3
b) We need to replace y by 8.
8 = 0.2*x
8/0.2 = x = 40
x = 40
Q3) y is inversely proportional to x (y = k/x), and y = 8 when x = 30.
Then we get:
8 = k/30
Then the value of k is:
8*30 = k = 240
then the relationship is:
y = 240/x
a) we need to replace x by 4
y = 240/4 = 60
y = 60
b) we need to replace y by 360
360 = 240/x
360*x = 240
x = 240/360 = 0.666...
x = 0.666...
