Answer:
C
Step-by-step explanation:
When you move the decimal either to the right or the left, you change the value. To divide any number by 10, move the decimal point one place to the left. For example:
0.7
7
70
700
7,000
So, for any decimal, when you move the decimal point one place to the right, you multiply that number by 10.

Answer:
General solution is

Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given cos x - sin x = √2 cos (3 x)
Dividing '√2' on both sides , we get

we will use trigonometry formulas
a) Cos ( A + B) = Cos A Cos B - sin A sin B
b) 
<u><em>Step(ii):-</em></u>
<u><em></em></u>
<u><em></em></u>


<u><em>Step(iii):-</em></u>
<u><em>General solution of cos x = cos ∝ is x = 2 nπ+∝</em></u>
<u><em>we have </em></u> 
The general solution of
is
⇒ 
⇒ 

<em><u>final answer</u></em>:-
General solution is
