That θ−x is actually 180+2θ−x<span> with respect to x-axis
</span>When it emerges out, it should be 180−2θ+x<span> with respect to x.
</span>Considering our original x, the deviation is 180−2θ ... since it is in opposite direction, we should add 180 to it which makes <span>360−2θ
</span>
we take succesive images of every image on its opposite mirror till the image finally ends to the other side of the opposite mirror...
u should end up getting a arithmetic series for the angle for the image formed first 1 and i.this angle should not exceed 180 degree as the image will go behind the mirror..then the total no will be added for both to get the formula.
3×2+14=20
20×3+18=78
78×4+22=334
334×5+26=1696
1696×6+30=10206
Hence, the question mark should be replaced by 10206
Answer: D
Step-by-step explanation:
Find 10% by moving the decimal point one place to the left, so 10% of 18.75 would be 1.875 then half of that would be 5%
15% would be about 1.88 + 0.94 = 2.82
The tip was really a little over 15% so you can say it is reasonable.
Our current list has 11!/2!11!/2! arrangements which we must divide into equivalence classes just as before, only this time the classes contain arrangements where only the two As are arranged, following this logic requires us to divide by arrangement of the 2 As giving (11!/2!)/2!=11!/(2!2)(11!/2!)/2!=11!/(2!2).
Repeating the process one last time for equivalence classes for arrangements of only T's leads us to divide the list once again by 2
