    no, it is just -k t/m (unless m is a function of t, which would make it more complicated)

    yes, that is why they are called constants. (if i didn't know any better, i could swear maskall has hacked into your account....., you're starting to sound like him)

    it depends on if the variable is dependent on the w.r.t, or if it is independent (which is otherwise known as a constant).

    e^(-kt ln m)=(e^ln m)^-kt=m^-kt
