Answer:
60
Step-by-step explanation:
<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 :)
Answer:
what the heck is this
Step-by-step explanation:
48 ÷ 12 + 7 x 2 ÷ 2 - 1

F(x) = 8 - 10xg(x) = 5x + 4
(fg)(x) = (8 - 10x)(5x + 4)
(fg)(x) = 40x + 32 - 50x^2 - 40x
(fg)(x) = 32 - 50x^2
(fg)(-2) = 32 - 50(-2)^2
(fg)(-2) = 32 - 200
(fg)(-2) = -168
