Re-write it properly first, in all-algebraic language:

'

7 + 8j + 7 -2j

'

Now put like terms together:

'

7 + 7 +8j - 2j

'

Then simplify by doing the arithmetic:

'

14 + 6j.

'

And there you are!

What 8j-18 equals 14?

To solve for "j" in the equation 8j - 18 = 14, you can isolate the variable by adding 18 to both sides of the equation. This will give you 8j = 32. Then, divide both sides of the equation by 8 to find that j = 4.

A particle of mass 3kg moves under a force of 4i plus 8j plus 10k . if the particles start from rest and was at the origin initially its new coordinATE AFTER 3 SEC will be?

To find the new coordinates of the particle after 3 seconds, we need to integrate the acceleration function twice. Given the force function F = 4i + 8j + 10k, we can find the acceleration using Newton's second law (F = ma) and then integrate it twice to find the position function. The final position coordinates can be determined by plugging in t=3 seconds into the position function.

What is 8j cubed k minus 4 jk cubed minus 7?

That completely depends on what numbers 'j' and 'k' are, and it changes immediately if either of those changes.


A particle moves so that its position in m. as a function of time in sec is r equals i plus 4Tsqj plus tk. write expressions for a. its velocity and b. its acceleration as functions of time?

a. The velocity of the particle is the derivative of its position function with respect to time. In this case, the velocity would be v = 4t^2j + k. b. The acceleration of the particle is the derivative of its velocity function with respect to time. So, the acceleration would be a = 8tj.
