Answer:
y(0) = 0.25 feet
Step-by-step explanation:
We are given the following information in the question:
The displacement from equilibrium of an oscillating weight suspended by a spring =
where y is the displacement in feet and t is the time in seconds.
Here, cos is in radians.
1) t = 0
y(0) = 0.25 feet
2) t = 
3) t = 
The negative sign indicates the opposite direction of displacement.
I suggest reading them over and over again to remember them. I know it sounds annoying, but trust me, it'll pay off.

Answer: 4258.33
Step-by-step explanation: 365 x 35= 12775/3= 4258.33
Hi there!
x - 3y = 9
x = 9 + 3y
-4x + y = 8
-4(9+3y) + y = 8
-36 - 12y + y = 8
-36 - 11y = 8
-11y = 44
-y = 4
y = -4
x - 3y = 9
x - 3(-4) = 9
x + 12 = 9
x = 21
So, your answers are y = -4 and x = 21.
Hope this helps!
