There is no logical relationship between the prepositions.
You can put any angle and its cosine there.
You can put, for example:
Cos(90)=0 or Cos(0)=1... Both are correct options...
If your teacher wrote that, he doesn't know to write very good...
Good luck!

Answer:
Depends on what animals ya'll busters are talking about, a good estimate would be a least 10 though.
Put each variable's value in parentheses:
P = 2(2.5) + 2(3 2/5)
Solve and get P = 5 + 6 4/5 which as 11 4/5.
The mixed number answer is 11 4/5
When a point is reflected across the x-axis, it's y value is flipped. Here is a formula for your future reference:
X-axis reflection: (x,-y)
Using your given coordinates, you simply plug the numbers in, resulting in final coordinates of (5,3.5).
Because the problem asks for the distance between the two points, you now have to find the difference between -3.5 and 3.5, which is 7.
There you go; the distance between the points is 7 units.
