D=546m. r=1.3m/sec. 546m=1.3m/sec(t).
546m divided by 1.3m/sec = t = 420 sec (the meters will cancel out, leaving the answer to just seconds).
420 seconds divided by 60sec/min = 7 minutes.
Answer:
4
Step-by-step explanation: i guessed and got it right
sorry if youre looking for an actual education!!
The complex solutions come in pairs and the only difference between them is the sign between the real and imaginary part, so one of the other two solutions is

. The third solution can be easily found using the rational root theorem, and it's equal to -1.
