Pre-image point N (6,-3) was dilated to point N(2,-1) What was the scale factor used?
tangare [24]
Answer:
The scale factor is 1/3

Explanation:
Given that the original point is has coordinates (x,y) and that the dilated point has coordinates (x',y'), we can see that:
x' = k * x
y' = k * y
where k is the scale factor

Now, for the given point we have:
original point = (6 , -3)
dilated point = (2 , -1)
Now, applying the above formula, we will find that:
For x-coordinate:
2 = k * 6
k = 2/6
k = 1/3
Check using the y-coordinate:
-1 = k * -3
k = -1 / -3
k = 1/3

From the above, we can confirm that:
k = 1/3

Hope this helps :)

Determine en donde la funcion dada es creciente,concava hacia riba y concava hacia abajo. y= x3–3x–1
Minchanka [31]

Answer:

Es creciente en los siguientes intervalos: [-\infty,-1] U [1,\infty]

Es concavo hacia abajo en el intervalo: [-\infty,0)

Es concavo hacia arriba en el intervalo: (0,\infty]

Step-by-step explanation:

Sea la función:

f(x)=x^{3}-3x-1

Para determinar el intervalo de crecimeinto debes determinar la primer derivada de la función (f'(x)). El intervalo donde f'(x) > 0 es creciente.

La derivada de f(x) es:

f'(x)=3x^{2}-3

Entonces es creciente en los siguientes intervalos:

[-\infty,-1] U [1,\infty]    

Ahora para determinar la concavidad debemos determinar la segunda derivada de la función (f''(x)). Si f''(x) > 0 la función es concava hacia arriba, si f''(x) < 0 la funcion es concava hacia abajo.

La segunda derivada de f(x) es:

f''(x)=6x        

Por lo tanto:

Es concavo hacia abajo en el intervalo: [-\infty,0)

Es concavo hacia arriba en el intervalo: (0,\infty]

Espero te haya ayudado!

What equation can be used?
Kryger [21]

Answer:

f(x)=89x+1800

Step-by-step explanation:

$1800 is spent on a washing machine. This number never changes, so we just need to add that to our annual total

$89 is spent every year. This means that this number needs to be with our variable, x, as it is dependent on the number of years that occur. When we put these two things together, we get the following equation:

f(x)=89x+1800

Elena read three times as many pages as Noah. She read 27 pages. How many pages did Noah read?
Jobisdone [24]

1. Noah reads 9 pages.

2. The price of one pizza is $9.

3. Lin shares her stickers is 9.

1.Given,

Elena read three times as many pages as Noah.

and, She read 27 pages.

Now, According to the question:

3x = 27

x = 27/3

x = 9

Hence, Noah reads 9 pages.

2. Given,

Diego paid $27 to have 3 pizzas delivered

and, $35 to have 4 pizzas delivered

In the question, In place of $ 35 should be $36

So, we take the $36

Now, Diego paid $27 to have 3 pizzas delivered

$36 to have 4 pizzas delivered

Let x be the price of 1 pizza

then, 4x = 36

x = 36/4

x = $9

Hence, The price of one pizza is $9.

3. Given,

Lin has 27 stickers.

and, She gives 3 stickers to each of her friends.

Now, 27 is divided by 3  = 9

Hence, Lin shares her stickers is 9.
