simplify : the exact value of sin 240
Explanation: sin(240)=sin(60+180)=-sin60

Final answer: the required vaalue of the sin 240 is -0.87
Answer:
see explanation
Step-by-step explanation:
The translation represented by ![\left[\begin{array}{ccc}1\\4\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%5C%5C4%5C%5C%5Cend%7Barray%7D%5Cright%5D)
interprets as a shift of 1 unit to the right ( add 1 to x- coordinate ) and a
shift of 4 units down ( subtract 4 from the y- coordinate ), then
(1, 4 ) → (1 + 1, 4 - 4 ) → (2, 0 )
(4, 4 ) → (4 + 1, 4 - 4 ) → (5, 0 )
(6, 2 ) → (6 + 1, 2 - 4 ) → (7, - 2 )
(1, 2 ) → (1 + 1, 2 - 4 ) → (2, - 2 )

logₐaˣ=x
logₐa=1
log(ab)=loga+logb
logₐx=y means a^y=x
3log₃6=log₃216=log₃(2³ times 3³)=log₃(2³)+log₃(3³)=log₃(8)+3
answer is log₃(8)+3 or 3(log₃(3)+1)
Given:
The center of the circle = (-2,1).
Circle passes through the point (-5,3).
To find:
The equation of the circle.
Solution:
Radius is the distance between the center of the circle and any point on the circle. So, radius of the circle is the distance between the points (-2,1) and (-5,3).




On further simplification, we get


The standard form of a circle is:

Where, (h,k) is the center of the circle and r is the radius of the circle.
Substitute h=-2, k=1 and
.


Therefore, the equation of the circle is
.
