Given your answer is say x<3, "x is less than 3", that means that 3 is not included in your solution set. The interval (-∞, 3); note the use of parenthesis. If the interval is [-3,6), this means that in your solution 3 is included but not 6. That is to say, 3≤x<6. [3,6]; both are included. (3,6) none is included.
<u>Answer:</u>
D) R0 , 360°
<u>Explanation:</u>
<u>We are given that the rotation is:</u>
(x,y) --------> (x,y)
This means that the point is rotated back into its original position.
This means that full rotation occurred.
Since the full rotation is 360°, therefore, the correct answer is D
<u>For the other options:</u>
<u>Rotation 90° gives:</u>
(x,y) ----------> (-y,x)
<u>Rotation 180° gives:</u>
(x,y) ----------> (-x,-y)
<u>Rotation 270° gives:</u>
(x,y) ---------> (y,-x)
Hope this helps :)
In a right angled triangle 'efg' cos a = 3/5
From Pythagoras theorem the third side will be 4
cos a =3/5
sin a =4/5
sin 2a =2 x 4/5
sin 2a= 8/5
