Step-by-step explanation:
The distance between the points is the magnitude of their difference.
|(-2-3i) -(3+9i)| = |-5 -12i| = √(5² +12²) = 13
The distance between the point is 13 units.
The value of the constant k when the value of x and y is 7 and 3 respectively in the equation xy=k is 21.
<h3>What is an equation?</h3>
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The value of the constant k when the value of x and y is 7 and 3 respectively in the equation xy=k can be written as,
![xy=k\\\\(7) \times (3 ) =k\\\\k= 21](https://tex.z-dn.net/?f=xy%3Dk%5C%5C%5C%5C%287%29%20%5Ctimes%20%283%20%29%20%3Dk%5C%5C%5C%5Ck%3D%2021)
Hence, the value of the constant k when the value of x and y is 7 and 3 respectively in the equation xy=k is 21.
