Write 3 quadratic equations that are NOT
equivalent, each forming a graph with vertex (-2, 3)
Answers
Answer:
the vertex of a quadratic equation:
a*x^2 + b*x + c = y
Is located at:
x = -b/2a.
In this case, x = -2
Then:
-b/2a = -2.
And we also have that:
a*(-2)^2 + b*-2 + c = 3
Then we have two equations:
-b/2a = -2
a*(-2)^2 + b*-2 + c = 3
We have only 2 equations and 3 variables, so we can just give the variable c different values and we will find different quadratic equations that are not equivalent.
Let's begin with c = 0, our equations are:
-b/2a = -2
a*(-2)^2 + b*-2 + 0 = 3
In the first equation we can isolate b and get:
b = 4*a
Now we can replace this in the other equation and solve this for a.
a*4 + 4*a*-2 = 3
-4*a = 3
a = -3/4
then:
b = 4*a = 4*-3/4 = -3
The first quadratic equation is:
(-3/4)*x^2 - 3*x = y.
Now, to find the second let's use a different value of c.
c = 1
b = 4*a
a*(-2)^2 + b*-2 + 1 = 3
Let's solve in the same way as before:
a*4 + (4*a)*-2 + 1 = 3
-4*a = 2
a = 2/-4 = -1/2
b = 4*-1/2 = -2.
Then our equation is:
(-1/2)*x^2 - 2*x + 1 = y
For the last equation, let's use c = 2.
then our equations are:
b = 4*a
a*(-2)^2 + b*-2 + 2 = 3
Same as before, replace the first equation in the second.
a*4 + (4*a)*-2 + 2 = 3
-4*a + 2 = 3
-4*a = 1
a = -1/4
Then:
b = 4*(-1/4) = -1
Our third equation is:
(-1/4)*x^2 - 1*x + 2 = y
Now, below you can see all of them graphed.
Where red is the first one, blue the second and green the third one. (and as you can see, all of them share the vertex (-2,3) )

Conocido popularmente como el Lanzón, es una escultura elaborada por la cultura Chavín de Perú. Este gran monolito data, aproximadamente, del año 1000 a. C. y está situado en el Viejo Templo del centro religioso y ceremonial de Huantar.
Cierto día en una visita cultural, Pedro decide representar el Lanzón Monolítico con una escala de 1:103 cuya medida es de 4,41 cm.
Teniendo en cuenta los datos de la situación. ¿Cuánto mide la altura real exacta del Lanzón en metros?
Answers
Answer:
La altura real del Lanzón Monolítico es de 453.23 centímetros, o 4.53 metros.
Step-by-step explanation:
Dado que la representación a escala del Lanzón Monolítico mide 4,41 centímetros, y que dicha escala tiene un valor de 1:103 respecto de la medida real de la escultura, para representar la altura real de la misma se requiere realizar el siguiente cálculo:
1 = 4,41
103 = X
(103 x 4,41) / 1 = X
454.23 = X
Por lo tanto, la altura real del Lanzón Monolítico es de 453.23 centímetros, o 4.53 metros.

Out of 100 people, 40 paid with cash, 55 paid with a credit card and 5 used a gift card. Based on this information, what is a reasonable prediction of the number of people paying with cash if they had 600 customers?
Answers
Answer:
Cash = 240, Credit = 330, Gift = 30
Step-by-step explanation:
We know from this the precentage of people using different payment methods
Cash = 40/100 = 40%
Credit card = 55/100 = 55%
Gift card = 5%
We can then find the number of people using each method regardless of total amount of people
Cash = 40% * 600 = 240
Credit = 55% * 600 = 330
Gift card = 5% * 600 = 30
Total = 240 + 30 + 330= 600
Answer:
240
Step-by-step explanation:
Set up a proportion. Out of 100 people, 40 people paid with cash. Out of 600 people, x people paid with cash.
[tex]\frac{40}{100} =\frac{x}{600}[/tex]
Cross multiply and solve for x.
[tex]24000 = 100x\\24000/100=100x/100\\240 =x\\x=240[/tex]
240 customers paid with cash.
