Answer:
25
Step-by-step explanation:
The distance is the magnitude of the difference:
|(2 -3i) -(9 +21i)| = |-7 +24i| = √((-7)² +24²) = √625 = 25
The distance between the two points in the complex plane is 25 units.

To find the midpoint of line FG, we have to use the following midpoint formula , which is

In the given question,
x1= -5, y1= -3 , x2=-3, y2=3
Substituting the values of x1,y1,x2 and y2 in the formula of the midpoint, we will get

So the midpoint of the given line is (-4,0) and hence the correct option is the first option .

Answer:
the square root of 105 lies between 10 and 11
Step-by-step explanation:
Which perfect squares "box" 105 in? 10^2 = 100 and 11^2 = 121.
The square roots of 100 and 121 are 10 and 11.
Thus, the square root of 105 lies between 10 and 11.
