1. Rotation by 180° (clockwise or anti-clockwise) about the origin has a rule:
(x,y)→(-x,-y).
Then
(-4,-10)→(4,10).
2. Translation 1 unit to the right has a rule:
(x,y)→(x+1,y).
Then
(4,10)→(5,10).
3. After rotation and translation the image of point (-4,-10) is point (5,10).
Answer: (5,10).
Answer:
For D I believe it would be 6
Step-by-step explanation:
I believe 6 because is you do 108÷18 you get 6 and then it would be 6/108 = 7/18 which is true.
Might not be correct and I don't know the others sorry!
Answer:
r = 3.21
Step-by-step explanation:
250/360 = x/60
x = 41.7 cm
This is because when the whole circle is 250 cm (angle is 360 degrees), 60 degrees means that the arc is 41.7 cm.
The population ten years ago was 6,000.
Because the population doubled you divide 12,000 by 2
12,000 / 2 = 6,000
