How does a compare to b a=cos(0+2pi) b=cos(-0)

You can use the double angle formula for A.
Cos(0 + 2pi) = Cos(0)*Cos(2*pi) - Sin(0)*Cos(2*pi)
Cos 0 = 1
Cos (2*pi) = 1
Sin(0) = 0
So you are left with cos(0 + 2pi) = 1 * 1 = 1

there are a couple of ways of handling Cos(-0) 
The First and most obvious way is to put it in your calculator just as you see it. Most calculators would do it like this
Cos(
+/-
0
)
=
The result should be 1
You could try using cos(0-0) You will get the same answer -- 1.

Skew lines(segments) are lines(segments) in 3 dimensions that do not intersect the given segment and are not parallel to it.  ae, bf, eg, and fh are your skew segments.  i hope that : )

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
