Answer:
middle one
Step-by-step explanation:
What's the difference between A) and C)??
There should be an E) because the correct answer would be in either of these forms:
Hello :
sin(x) + cos(x) = √2(1/√2 sin(x) +1/√2 cos(x))
but : 1/√2 = cos(π/4) = sin(<span> π/4)
</span>sin(x) + cos(x) = √2( cos(π/4)sin(x) + sin( π/4) cos(x)) =√2<span>sin(x + π/4)
</span>because : cos(π/4)sin(x) + sin( π/4) cos(x)=sin(x + π/4) by identity :
sin(a+b) = sina cosb +cosa sinb
Pat attention to the ending of the numbers. If there are an odd amount of odds, it's going to be odd. If there is an even amount of odds, it's going to be even. If there's only evens, it's only going to stay even.
1 cm = 10 mm
1 cm^2 = 100 mm^2
0.6 cm^2 = 0.6 * 100 mm^2 = 60 mm^2
