leaving only x
Answer:
Step-by-step explanation:
Given
The initial lower left corner of the square at:
Required
Its new position after 5 units left and 7 units right translations
When a point is translated to the left by a units, the rule is:
In this case:
So:
<em>So, the new point is: (-5,0)</em>
When a point is translated to the right by b units, the rule is:
In this case:
So:
<u><em>So, the new point is: (2,0)</em></u>
Answer:
Step-by-step explanation:
If you draw a line from the origin (0,0) to L ( the original point ) and a different line from the origin to the image L' you can see the angle of rotation as being
90 degrees and that the rotation is clockwise.
the rule is (x, y) become ( y, -x)
Answer:
31.4 cm
Step-by-step explanation:
se the forumula of the circonference 2r*pi. We aready have the 2 times radius (20 cm) and pi, but we have to divide by 2 the result because it is a semicircle. so 20*3.14/2= 31.4 cm
