Answer:
The dilation is an enlargement
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its corresponding sides is equal and this ratio is called the scale factor
In this problem Triangles A'B'C' and ABC are similar by AA Similarity Postulate
Let
z------> the scale factor
so
substitute the values
The scale factor is greater than 1
therefore
The dilation is an enlargement
21 because 9+10 is actually 21
Answer:
-6
Step-by-step explanation:
Formula for mid point.
(x1/2+x2/2 , y1/2+ y2/2)
Mid point=
(1/2+ (-3)/2 , 4/2+ 7/2)
(-2/2 , 11/2)
(-1, 5.5)
Answer:
4.5 cm.
Step-by-step explanation:
We have been given that circle O has a circumference of approximately 28.3 cm.
We will use circumference formula to solve for the radius of our given circle.
Upon substituting the measure of circumference in above formula we will get,
Therefore, the radius of circle O is 4.5 cm.
