They could be rational, irrational, whole, or an integer.
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
Answer:
I believe it should be; 1/3, 0.85, 5/4
Answer:
2x² + 3x + 4
Step-by-step explanation:
Using synthetic division to divide by x - 1
1 | 2 1 1 - 4
↓ 2 3 4
---------------------
2 3 4 0 ← remainder = 0
-----------
↑ quotient
quotient = 2x² + 3x + 4
