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

Answer: 1 yes 2 no
YOU PROMISED BRAINLIEST
Step-by-step explanation:
Answer:
the answer is 12. hoped this helped
Step-by-step explanation:
first find out what 5* 12 is. 5* 12= 60
then 12* 4. 12* 4=48
finally subtract 60 and 48 witch is 12
5x + 18y = 23
x + 3y = 2 .....multiply by -5
----------------
5x + 18y = 23
-5x - 15y = -10 (result of multiplying by -5)
----------------add
3y = 13 <=== the resulting equation
