The amplitude of 
is the absolute value of 
. So first you need to condense the given function into one sine expression.
Recall that
so you need to choose 
and 
accordingly.
If we line up the terms of the given function with the expanded one above, we should have
Now, using the Pythagorean identity,
so the amplitude is √29.
Just for completeness, we also get
where 
is any integer.
Answer:
son 1000 metros en un kilometro
Step-by-step explanation:
The diameter is 6. Explanation:
radius: 3.14r^2
28.26=3.14r^2
28.26/3.14=r^2
r^2=9
r=3
and we know that diameter is two times the radius so:
3*2=6
diameter equals 6.
if you want to check it plug back in:
3^2 * 3.14 = 28.26
hope this helped :)
