Answer:
3, - 6 )
Step-by-step explanation:
Since the dilatation is centred at the origin , multiply the original coordinates by the scale factor, that is
(6, - 12 ) → ( × 6, × - 12 ) → (3, - 6 )
Answer:
sin 3 θ = 3 sin θ - 4 sin³θ
Step-by-step explanation:
<u><em>Step(i):</em></u>-
Given sin 3 θ
= sin ( 2θ + θ )
apply trigonometric formula
<em> sin ( A + B) = sin A cos B + cos A sin B </em>
<em> sin 2 A = 2 sin A cos B</em>
<em> Cos 2 A = 1 - 2 sin² A </em>
<em> cos ² A - sin ² A = 1</em>
<u><em>Step(ii):</em></u>-
sin 3 θ = sin ( 2θ + θ )
= sin 2θ cosθ + cos2θ sin θ
= 2 sin θ cos θ cos θ +( 1 - 2 sin² θ )sin θ
= 2 sin θ (cos² θ ) + sin θ- 2 sin³ θ
= 2 sin θ ( 1- sin²θ) + sin θ- 2 sin³ θ
= 2 sin θ - 2sin³θ + sin θ- 2 sin³ θ
= 3 sin θ - 4 sin³θ
<u><em>Final answer</em></u> :-
sin 3 θ = 3 sin θ - 4 sin³θ
<u>Solution </u><u>-</u><u>:</u><u> </u>
Let's begin-
solve,,,
Now,,According to BODMAS rule fist we divide ,
Now , we multiple
and this is our final answers

Division → Multiplication → Addition → Subtraction
- B stand bracket
- O stand of
- D stand division
- M stand Multiplication
- A stand for addition
- S stand for subtraction
The correct answer is B
3 is the real solution... and +4i and -4i are the imaginary solutions
1,521 millileters is equal to 15.21 deciliters.
In a deciliter, there are 100 milliliters. So, for this problem you would divide 1,521 by 100 to find the equality of milliliters to decimeters. Solving this, would give you 15.21 decimeters.
I hope this helps!!
