I think 1 is your answer  Because 3 points will determine a plane.

frozen [14]

Your distance is 1424 and your rate is 356. As you said, d = r*t. Since you don't have the time you would do 1424 divided by 356. This leaves you with a time of 4 hours. (Don't forget units!)

Find the sum of the geometric series 6Σ3i i=2
topjm [15]

\sum_{3}^{6}2=\sum_{0}^{3}2=2+2+2=\boxed{6}

Or did you mean:

6\times\sum{3i}=6\times\sum{6}=6\times6=\boxed{36}

Since BC is parallel to DE, triangles ABC and ADE are similar. What are the lengths of the unknown sides?
polet [3.4K]

Answer:

Since we have BC ║ DE, we know that:

AB/AD = BC/DE

12/(12 + 4) = BC/12

12/16 = BC/12

BC = (12 · 12)/16 = 9 (in)

Applying the pythagorean, we have:

AB² + BC² = AC²

12² + 9²     = AC²

225           = AC²

AC             = √225 = 15 (in)

Using the information about the parallel lines again, we have:

AC/CE = AB/BD

15/CE = 12/4

CE = (15 · 4)/12 = 5 (in)

So the answer is B
