    Does Differentiating e^(-x) and e^(3x+4) Follow Standard Rules?

    1. d(e^-x)/dx = -e^-x, use the chain rule to solve it. 2. Again, use the chain rule, take the derivative of e first then 3x+4

    Velocity & Distance of Long Jumper on the Moon

    Ok, this is how I did it step by step. First I found the time it toke from the ground to the maximum height using: Vertical direction: d = v1 + a(t)^2 / 2 0.82 = 0 + 9.81(t)^2 / 2 0.82 / 4.905 = t^2 t = 0.41 t(total) = 0.82 Then I multiply that by 2 to get the time it takes for him...

    Velocity & Distance of Long Jumper on the Moon

    Homework Statement Long jumper jumps 8.12 m, reaching a height of 0.84 m half way through his jump. What was his velocity as he left the ground? Also, how far would he be able to jump on the moon (g = 1.63 m/s^2) and how much time would be spend off the lunar surface.Homework Equations d = v1...
