Rectangle QRST is dilated with the origin as the center of dilation to create rectangle Q'R'S'T'.

scoundrel [369]

Answer:

Rule: dilation about the origin by a scale factor of 2

Step-by-step explanation:

Given

See attachment for QRST and Q'R'S'T

Required

The dilation rule

First, we calculate the scale factor (k)

From the attachment, we have:

$QR = 4$

$Q'R' = 8$

k, is then calculated as:

$k = \frac{Q'R'}{QR}$

$k = \frac{8}{4}$

$k =2$

<em>Hence, QRST is dilated by a factor of 2</em>

Find all integers $n$ for which $\frac{n^2+n+1}{n-1}$ is an integer.

Grace [21]

$\dfrac{n^2+n+1}{n-1}=\dfrac{(n-1)^2+3(n-1)+3}{n-1}=n-2+\dfrac3{n-1}$

The remainder term $\dfrac3{n-1}$ will never vanish, and will always be rational as long as the denominator is not 1, 3, or -3.

$n-1=1\implies n=2$
$n-1=3\implies n=4$
$n-1=-3\implies n=-2$
