Answer:
2.24
Step-by-step explanation:
when there are the lines outside of it, it will always become positive.
Answer:
from least to greatest
1.25, -(-2). 3, 4
Step-by-step explanation:
it's just from least to greatest and to negatives cancel out leading 2 to become a positive number. The difference between 1.25 and 2 is 0.75 so you would have them 0.75 distance a part and the rest with 1 distance apart.
The motion can be modeled as

where
x = the position below the equilibrium position
T = the period of the motion
t = time
The weight returns to its equilibrium position when x = 0.
This occurs when

That is,

Because the weight returns to the equilibrium position when t = 3 s, therefore
T = 12 s
The motion is

When t = 1 s, the position of the weight from equilibrium is

Answer:
Speed / velocity (that's a slash) are always distance over time. divide 54 by 45
Given:
total = 750
ratio = 7 : 8
We need to get the ratio of the number to its total
7 + 8 = 15 ; 7/15 and 8/15 is the ratio of the number to its total.
We multiply these ratio to the total of 750
7/15 * 750 = 350
8/15 * 750 = 400
7:8 is equal to 350:400
