Answer:
2πx3
Step-by-step explanation:
Answer:
Make sure the mode is on degree and not radian! Common mistake
Answer:
D
Step-by-step explanation:
Lengths:
WX: 2
XY: 2
WY: sqrt[(4-2)² + (2-4)²]
sqrt(4+4)
4sqrt(2)
W'(8, 16), X'(8, 8), Y'(16, 8)
W'X': 8 --> 4 × 2
X'Y': 8 --> 4 × 2
W'Y': sqrt[(16-8)² + (8-16)²]
sqrt(64 + 64)
8sqrt(2) --> 4 × 2sqrt(2)
D is a dilation with factor 4
first you do 7100 times 10=71,000
