Answer: 25%
20 divided by 80= .25x 100= 25%
10% i believe because it went up by 10 sorry if wrong

9×9=81 hope that this helps you and have a great day :)
Answer:
I cant see if there is a image or not
Step-by-step explanation:
Answer:
(4.0x - 12)i . (5/3)i
Step-by-step explanation:
Potential energy = Workdone
Workdone = Force x distance
Force = F = (4.0x - 12)i N
Workdone = 20J
At x= 0
F = -12i
/F/= 12
Workdone = Force x distance
20 = 12 x distance
Distance = 20/12
= 5/3
In the vector form distance is written as (5/3)i
Since Workdone/ Energy is scalar, U can be expressed as a dot product of the vectors of Force and distance :
(4.0 x - 12)i . (5/3)i
