Answer:
y = 4 sin( 0.5t - 
) - 2
y = a sin ( 2t - 
) + 2
Step-by-step explanation:
In the first question,
amplitude = 4
Period = 
phase shift = 
Vertical shift = -2
Angular velocity , w = 
Here, w = 
= 0.5
The general equation of a wave is
y = a sin( wt + ∅ )
Putting above values in the equation,
y = 4 sin( 0.5t - ) - 2
In the second question,
Amplitude is not given so we will take it as a.
time period = 
w = 2
Phase shift =
Vertical shift = 2
The equation is
y = a sin ( 2t - ) + 2

3/4 is bigger than 2/5. Hope that helps
Answer:
Step-by-step explanation:
the information we have is:
- the radius of the circle in the base:
(u for units)
- and the height of the cone:
to find the volume we need the formula for the volume of a cone:
where r is the radius and h is the height.
Substituting the known values to find the volume:
the volume in terms of is 
and if we substitute the value of pi: 
we get:
