Answer:
i dont think you can simplify it any more
Step-by-step explanation:
Reorder 2 cos (2y) and sin (2y)
= sin (2y)(2 cos(2y))
Remove parenthesis
= sin (2y) * 2 cos (2y)
Reorder sin (2y) and 2
= 2 * sin (2y) cos (2y)
Apply the sine double-angle identity
= sin (2(2y))
Now multiply 2 by 2
<u>= sin (4y) </u>
Answer:
13.4
Step-by-step explanation:
1/3 * 3x + 5.2y
1/3 * 3(3) + 5.2(2)
1/27 + 10.4
[(21-13)+(32-24)] x 4
[(8)+(8)] x 4
16 x 4
= 64
