Question

The diagram shows a dilation of line AB
about the origin O. Determine the scale
factor of the dilation by following these
steps.

1.measure these lengths
OA=_______units
OA’=_______units

Answer 1

Answer:

For e-2020 OA=2 units and Oa' = 3 units

Step-by-step explanation:

Ob=3.0 units

OB'= 4.5 units

Ab=2.2 units

AB'=3.3 units

Oa'/OA=1.5 units

Ob'/Ob=1.5 units

A'B'/AB= 1.5 units

Answer 2

Following are the calculation to the length:

Given:

Please find the given question.

To find:

length=?

Solution:

Any correct equation in the form concept any parameter for r:

$\bold{A(2,-1)}\\\\\bold{B(3,1)}\\\\\bold{AB=\sqrt{(1-1)^2+(1+1)^2} =\sqrt{(0)^2+(2)^2}=\sqrt{4}=2}$

Calculating the convert scalar product:

$\bold{2 \longrightarrow 4}$

So,

$\bold{A'(3,-2)}\\\\\bold{B'(4,2)}$

over down of equation their scalar product to zero:  

$\bold{OA=\sqrt{4+(-1)^2}=\sqrt{4+1}= \sqrt{5}\ units}\\\\\bold{OA'=\sqrt{3^2+(-2)^2}=\sqrt{9+4}= \sqrt{13}\ units}$
