B. 08.2
C. 02.8
D. 2.80
Step-by-step explanation:
For a wave:
y = A sin (2π/T x − φ) + B
A is the amplitude,
T is the period,
φ is the phase shift,
and B is the offset.
The given wave is:
f(x) = -5 sin(x + 2π) − 4
So the amplitude is -5, the period is 2π, and the phase shift is -2π.
Answer:You round 1 1/8 to 1 and 9/10 to 1 (since you are estimating) and then you add 1+1+1+1, which is 4 because to find perimeter you add the lengths and the widths.
y= 3/4x-7
4x- 6y=50
5/6 7/9 -4/5
