Answer:
3.28 x 10^-4
Step-by-step explanation:
0.000328 = 3.28 x 10^-4
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:
x nth term =6–3(n-1)
Step-by-step explanation:
Since they start at 6 its X nth term n=6- but since the since one is 6 its 3(n-1) so x nth term=6-3(n-1)
Answer:
$9257.5
Step-by-step explanation:
plug into the equation known variables
4a + 3 = 15
- 3
4a = 12
÷ 4
a = 3
I hope this helps!
