Answer:
1. Send me the chart and ill get you the answer.
2. unit cost is $0.30
Step-by-step explanation:
<h3>Answer: C) none of the equations are identities</h3>
If you plugged theta = 0 into the first equation, then you would have
sin(45) + cos(45) = sin(0) + cos(0)
sqrt(2) = 1
which is a false equation. We don't have an identity here.
The same story happens with the second equation. Plug in theta = 0 and it becomes
cos(60) - sin(60) = cos^2(0) + tan(0)
1/2 - sqrt(3)/2 = 1 + 0
-0.37 = 1
which is false.
The answer I believe is the third choice.
3, -2, -7, -12
These all fit into f(n)-5=f(n+1)
The missing blank is 2 because 7+2=9.
A ) P=6n+18 where N is the number of triangles. There's always two '9's and the 6 is based on how many triangles there are.
