26.18 divided by 77 = 0.34. Therefore the percentage change = 66%
Answer: 9
Step-by-step explanation:
If you put all the numbers in order from least to greatest 9 is in the middle.
Another point on the line is (6,-1)
So there is an identity we'll need to use to solve this:
cos(x+y) = cosxcosy - sinxsiny
replace the numerator with the right hand side of that identity and we get:
(cosxcosy - sinxsiny)/cosxsiny
Separate the numerator into 2 fractions and we get:
cosxcosycosxsiny- sinxsiny/cosxsiny
the cosx's cancel on the left fraction, the siny's cancel on the right fraction and we're left with:
cosy/siny - sinx/cosx
which simplifies to:
coty - tanx
