Answer:
C ≈ 11.71 cm
Step-by-step explanation:
using the ratio arc AC : circumference C = angle at centre of sector : 360°
= 
, that is
= ( cross- multiply )
123 × C = 4 × 360 = 1440 ( divide both sides by 123 )
C = 
≈ 11.71 cm ( to the nearest hundredth )
Answer:wo consecutive integers would be 13 and 14 because 13 x 13 = 169 and 14 x 14 = 196 and the inequality fits inbetween perfectly.
Step-by-step explanation:
Answer:
Translate ABCD down 1, then reflect it over the y-axis
and
Reflect ABCD over the y-axis, then translate down 1
Step-by-step explanation:
First of all, the two steps are the same, just in a different order
Second, if you look at the instructions you can see what would happen to the quadrilateral. Reflecting over the y-axis would make the shape flip horizontally (left to right), as shown in the image. This means the points on the left move to the right, and the points on the right move to the left. Top and bottom points stay the same. And the "translation" just means to slide. In both the answers, it says "translate 1 unit down", which just means "move 1 unit down", which is exactly what happens in the image
