In order to find the value first multiply both sides by 100 to simplify the equation:
0.05w*100=15*100
5w=1500
Next, divide both sides of the equation by 5:
5w/5=1500/5
w=300
The final solution is w=300!
Hope i could help.
have a great day
Answer:

Period is 2π
Horizontal shift = 0
Step-by-step explanation:
We know that
and as
, so, we can write
Therefore, the if
then
(Answer)
Now, the period of
is 2π, hence the period of
is also 2π. (Answer)
Again.
, hence, the horizontal shift of
