I’m confused there are no numbers ?
The answer is 12.5% this is the correct answer
Answer:
-4 ≤ y ≤ 2 or [-4 , 2]
Step-by-step explanation:
The maximum of the function is +2 while the minimum is -4, the range is
-4 ≤ y ≤ 2 or [-4 , 2]
<edf is 86 vertical angles
< e + <edf + <efd =180 sum of the angles of a triangle
42+ +86 +<efd =180
128 + <efd = 180
subtract 128 from each side
<efd = 52
<efd + <dfg = 180 straight line
52+ <dfg = 180
subtract 52 from each side
<dfg = 128
Answer : 128
Cos2x = (cosx)^2 - (sinx)^2;
sin2x = 2sinxcosx;
Then, (2cos2x)/(sin2x) =2[ (cosx)^2 - (sinx)^2 ] / (2sinxcosx) = [ (cosx)^2 - (sinx)^2 ] / (sinxcosx) = (cosx)^2 / (sinxcosx) - (sinx)^2 / (sinxcosx) = cosx/sinx - sinx/cosx = cotx - tanx;
