Answer:
Step-by-step explanation:
The other root is 5 + 7i
So the distance between two points formula is :
c= the square root of (x1-x2)^2 + (y1-y2)^2
Therefore ...
(8-2)^2 + (2-9)^2
6^2 + (-7)^2
36+49= 85
Square root of 85= 9.22 approx.
Hence, the distance between the two points is 9.22
5 7/32 = 167/32
5/32 + 5/32 (2 wall thicknesses of the pipe) =10/32
167/32 - 10/32 = 157/32
= 4 29/32
