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.
Answer:
ray UV and ray UT
Step-by-step explanation:
The sides are the rays that make up the angle
ray UV and ray UT make up the angle VUT
Answer: 24^p
Step-by-step explanation:
8 ^p x 3
To simplify the above, multiply the whole numbers
8 x 3 = 24
24^p
Answer:
20%
Step-by-step explanation:
Use the formula:
The "|" symbol represents absolute value and the dashed line represents a division line.
| Theoretical Value - Actual Value |
Percent Error = -------------------------------------------------- × 100
| Theoretical value |
- 100 students is the theoretical value
- 120 students is the actual value
100 - 120 = -20
-20 / 100 = -0.2
|-0.2| = 0.2
0.2 × 100 = 20
The answer is 20%
