<PRE><B>Question 383249</B>
The intensity of a radio signal from the radio station varies inversely as the square of the distance from the station. 
-----
I = k/d^2
Solve for &quot;k&quot; using the following:
--------------------------

Suppose the intensity is 8000 units at a distance of 2 miles. 
8000 = k/2^2
k = 32000
----
Equation for this radio station:
I = 32000/d^2
======================

What will the intensity be at a distance of 8 miles?
I = 32000/8^2
I = 500
===================
Cheers,
Stan H.
