Triangle A″B″C″ is formed using the translation (x + 1, y + 1) and the dilation by a scale factor of 3 from the origin. Which eq

FromTheMoon [43]

Answer:

$B''C''=3BC$

Step-by-step explanation:

we know that

The length of segment B''C'' is equal to the length of segment BC multiplied by the scale factor

step 1

Find the length of segment BC

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

we have the points

B(1,-3),C(-3,-3)

substitute the values

$BC=\sqrt{(-3+3)^{2}+(-3-1)^{2}}$

$BC=\sqrt{(0)^{2}+(-4)^{2}}$

$BC=4\ units$

The segment B''C'' is equal to the segment BC multiplied by the scale factor

The scale factor is 3

$B''C''=BC(3)$

$B''C''=3BC$

substitute

$B''C''=3(4)=12\ units$

Two polygons are similar. The perimeter of the larger polygon is 85 meters and the ratio of the corresponding side lengths is $\

Alenkasestr [34]

Answer:

The perimeter of the other polygon is $34\ m$

Step-by-step explanation:

we know that

If two figures are similar, then the ratios of its perimeter is equal to the scale factor

Let

z---> the scale factor

x----> the perimeter of the other polygon

y----> the perimeter of the larger polygon

$z=\frac{x}{y}$

we have

$z=\frac{2}{5}$

$y=85\ m$

substitute and solve for x

$\frac{2}{5}=\frac{x}{85}$

$y=85*(2/5)=34\ m$
