Answer:
back at it again with the memes i got alot 2 or 1 meme per question
Step-by-step explanation:
<span>-6+14 =12-8x
-6+14 = 8
then
8 = 12 - 8x -12
8-12 = 12 - 12 -8x
8-12 = -4
and
12-12=0
then
-4 = -8x /-8
-4/-8 = -8x/-8
-4/-8 = 1/2
then
1/2 = x
so that: x = 1/2 = 0.5
hope that helps

The diagonal of length 2r forms the hypotenuse of a right angled triangle with one leg ( the width of the rectangle) = x. So by Pythagoras:-
(2r)^2 = h^2 + x^2 where h = height of the rectangle
h^2 = 4r^2 - x^2
h = √ (4r^2 - x^2) answer
Use the execution method or in other words use the substitute method and go from there..
Answer:
1) - 2 / (cos x + sinx)^2.
Step-by-step explanation:
1) I assume you want the derivative of (cos x - sin x) / ( cos x + sin x).
y' = (cosx + sinx)( -sinx - cosx) - (cosx - sinx)(-sinx + cosx)
---------------------------------------------------------------------------
(cosx + sinx)^2
= -sinxcosx - cos^2x - sin^2x - sinxcosx - (-sinxcosx+cos^2x+sin^2x-sinxcosx
-------------------------------------------------------------------------------------------------------
(cosx + sinx)^2
= -2sinxcosx - 1 - ( -2sinxcosx + 1 ) / (cosx + sinx)^2
= -2sinxcosx - 1 - ( -2sinxcosx + 1 ) / (cosx + sinx)^2
= - 2 / (cos x + sinx)^2.
