Which transformation was performed on PQRS to form P'QʻR'S'? (1 point)

REY [17]

Given:

A transformation was performed on PQRS to form P'QʻR'S'.

To find:

The transformation.

Solution:

The given graph shows two similar polygons. It means, dilation was performed.

From the given graph it is clear that,

$PS=2$ units

$P'S'=1$ units

Now,

$\text{Scale factor}=\dfrac{P'S'}{PS}$

$\text{Scale factor}=\dfrac{1}{2}$

A dilation factor of $\dfrac{1}{2}$ was performed on PQRS to form P'QʻR'S'.

Therefore, the correct option is (3).

The lines graphed below are parallel.the slope of the slope of red line is 2/5 .what is the slope of the green line

Yuliya22 [10]

Answer:

$\large\boxed{\text{the sloe}\ m=\dfrac{2}{3}}$

Step-by-step explanation:

$\text{Let}\\\\k:y=m_1x+b_1\\\\l:y=m_2x+b_2\\\\l\ \parallel\ k\iff m_1=m_2\\\\l\ \perp\ k\iff m_1m_2=-1\to m_2=-\dfrac{1}{m_1}$

$\text{We have the slope}\ m_1=\dfrac{2}{5}.\\\\\text{The slope of parallel line is the same:}\ m_2=\dfrac{2}{5}$
