Remember the pythagorean theorem.
a^2 + b^2 = c^2
The complex number is a+bi, the absolute value is 'c'
a^2 + b^2 = c^2
The complex number is a+bi, the absolute value is 'c'
Answer:
-0.25
Step-by-step explanation:
Coordinates of C =
Coordinates of D =
Let Coordinates of A= (x,y)
Since A point is located 1/4 the distance from C to D
So the remaining distance from point A to D is 3/4
Thus the ratio of CA : AD = m:n=1:3
Now to find points of A we will use section formula i.e.
Substituting the values:
Thus Find the x value for the point that is 1 over 4 the distance from point C to point D is -0.25
Hence option a is correct
