What is the difference between the Argand Diagram/Plane and the Coordinate Plane?

Argand diagram refers to a geometric plot of complex numbers as points z=x+iy using the x-axis as the real axis and y-axis as the imaginary axis.The complex plane (also called the Argand plane or Gauss plane) is a way to represent complex numbers geometrically. It is basically a modified Cartesian plane, with the real part of a complex number represented by a displacement along the x-axis, and the imaginary part by a displacement along the y-axis.

Step-by-step explanation:

number one is the correct answer

step-by-step explanation: dogs and cats are mentioned, no other animals

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
