Answer:
In bold.
Step-by-step explanation:
6/6 = 9/a
So a = 9.
6/c = a/4.5
6/c = 9/4.5 = 2
So c = 3.
By similar triangles:
d/5 = 6/ (6+6+3)
d/5 = 6/15 = 2/5
So d = 2.
Also by similar triangles
b/5 = 12/15 = 4/5
So b = 4.
Answer:
The integral diverges
Step-by-step explanation:
Consider the integral from 0 to infinity of

We can do this in parts

When we substitute limits infinity we find that the values become infinity
Hence the integral diverges
The given improper integral diverges
