Answer:
The graph that shows the dilation of the rectangle in the attached figure
Step-by-step explanation:
we know that
A dilation is a non rigid transformation that produce similar figures
If two figures are similar, then the ratio of its corresponding sides is proportional
In this problem we have that the scale factor is equal to 2
Remember that
If a scale factor is greater than 1, then the dilation is a enlargement
To find out the dimensions of the dilated figure multiply the original dimensions by the scale factor
The original dimensions of rectangle are
The dimensions of the dilated rectangle are
therefore
The graph that shows the dilation of the rectangle in the attached figure
Answer:
Step-by-step explanation:
(cos x+cos y)²+(sin x-sin y)²
=cos²x+cos²y+2 cos x cos y+sin²x+sin²y-2 sin x sin y
=(cos ²x+sin ²x)+(cos ²y+sin ²y)+2(cos xcos y-sin x sin y)
=1+1+2cos(x+y)
=2+2 cos (x+y)
=2[1+cos (x+y)]
=2 *2cos²((x+y)/2)
