Answer:
d = √149 = 12.2
Step-by-step explanation:
Distance between 2 coordinates: d = √[(x2 − x1)^2 + (y2 - y1)^2]
d = √[(0 - 7)^2 + (2 - -8)^2]
d = √[(-7)^2 + (10)^2]
d = √[49 + 100]
d = √149 = 12.2
Answer:
A
Step-by-step explanation:
calculate the ratios AB/DE BC/EF AND AC/DF。their ratios are 1/2
Answer:
There is no direct relation.
Step-by-step explanation:
8/6 = 4/3
16/8= 2/1
32/24= 4/3
If this were directly related, all of these would simplify to the same thing.
For this case we have the following vector:
v = (- 8, 2)
Using product point we have:
v.v = (-8, 2). (- 8, 2)
v ^ 2 = (-8) * (- 8) + (2) * (2)
v ^ 2 = 64 + 4
v ^ 2 = 68
v = root (68)
v = root (4 * 17)
v = 2 * root (17)
Answer:
v = 2 * root (17)
