Hi! Can you check my answers please? Thanks! And, can you help me with 3 please? I have tried and tried but I cannot solve it can you explain how? Thanks!
1.
Given a scale factor of 2, find the coordinates for the dilation of the line segment with endpoints (–1, 2) and (3, –3). (1 point)
(–2, 4) and (6, 6)
(2, 4) and (6, 6)
(–2, 4) and (6, –6)
(2, –1) and (–3, 3)
2.
Given a scale factor of 1 over 2 , find the coordinates for the dilation of the triangle with vertices at (0, 0), (0, 2) and (4, 0). (1 point)
(0, 0), (0, 4), (8, 0)
(0, 0), (0, 1), (2, 0)
(1/2, 1/2), (1/2, 1), (2, 1/2)
(2, 2), (2, 4), (8, 2)
3.
Gina uses a magnifying glass to look at bugs. A caterpillar that is 2 inches long appears 4.5 inches long through the glass. What is the scale factor? (1 point)
2.25
0.4
9
2.5
My answers:
1.(–2, 4) and (6, –6)
2.(0, 0), (0, 1), (2, 0)
3. ?????
I don't know. Sorry.
1.(-2,4) and (6,-6)
2. (0,0),(0,4),(0,8)
Noth sure what 3 is sorry. Hope this helped though.
i have the same questions
r u sure they are right
Sure, I can help you with question 3.
To find the scale factor, you can use the formula:
Scale factor = Dilated length / Original length
In this case, the dilated length is 4.5 inches (how the caterpillar appears through the magnifying glass) and the original length is 2 inches (the actual length of the caterpillar).
So, the scale factor is:
Scale factor = 4.5 inches / 2 inches = 2.25
Therefore, the correct answer is 2.25.
