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.
Answer:
4628
Step-by-step explanation:
We are given that
In 2000
The population of a small industrial town in 2000=12910
Depreciation rate, r=5% per year
We have to find the population in the year 2020.
Time from 2000 to 2020=20 years
Where FV=Future value
PV=Present value
Using the formula
FV=4628
Hence, the population in 2020 =4628
