Suppose the numbers are n, (n+1) and (n+2) where n is an integer
Then, , therefore

so it is not possible as n an integer
You can also see this by considering the sequences:
55, 56, 57 whose sum is 168
56, 57, 58 whose sum is 171
so there are no three consecutive numbers with sum 170.

Use the formula x+x+1+x+2 or 3x+3=170 to find x. x is the first number. Then add x+1 to find the second number. Then add x+2 to find the third final number.
x will equal 167/3 which is a decimal, so just plug it in to the 3 equations I mentioned above to find your 3 consecutive numbers. More questions? Just ask me!

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:

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

Add three data values to the following data set so the mean increases by 10 but the median does not change. The numbers are 42 3

777dan777 [17]

In order the numbers are 20, 29, 32, 37, 42.
So that means the median is 32. In order for the median to stay the same one of the three data values must be 32 as well as adding a number to each side of the ends. One 32 or less another 32or more.
The mean right now is: 20+29+32+37+42=160 and there are 5 values.
Mean: 160/5=32
For it to increase by 10 it has to be 42.
extra 3 numbers I used were 31, 32, & 113 (those are your answer)

The product of a binomial and trinomial is x^3+3x^2-x+2x^2+6x-2 which expression is equivalent to this product after it has been

Debora [2.8K]

Answer: First option.

Step-by-step explanation:

You know that the product obtained by multiplying a binomial and a trinomial is:

$x^3+3x^2-x+2x^2+6x-2$

Then, in order to simplify this product, it is necessary to add the like terms.

Therefore, the expression that is equivalent to this product after it has been fully simplified is:

$=x^3+(3x^2+2x^2)+(6x-x)-2\\\\=x^3+5x^2+5x-2$

You can observe that this matches with the first option.
