<span>x = 10 or x = -4. It's one of those 2, there's 2 solutions for what I solved.</span>
Answer:
x 0.27
Step-by-step explanation:
if they are both decreasing then just add the two percentages together then divide by 100 to give you your decimal answer
Set up a proportion like this

=
So your proportion would be:

We put x for offices because they are asking for the number o offices a crew can paint in 12 hours, and also we don't know the number of offices they can paint in 12 hours
so we cross multiply and we get
6x=60, we got 60 by multiplying 12 and 5
Now we divide both sides by 6 and we get
x=10
S the crew can paint 10 offices in 12 hours.

Answer:
Step-by-step explanation:
I believe that what you want to do here is to "differentiate" cos (2x - 1).
We must use the rule for differentiating cos x and also the chain rule, since the input to cos x here is (2x - 1).
(d/dx) is the derivative operator.
(d/dx) (cos x) = -sin x
(d/dx) cos (2x - 1) = - sin (2x - 1) * (d/dx) (2x -1) = -sin (2x - 1)(2) = -2sin (2x - 1)
