<PRE><B>Question 818363</B>
The depth of a lake can be calculated by the function y=.2x^2-10x+6 . 
Where x represents the distance from the Western edge. 
b) What is the diameter of the lake? Round to the nearest thousandth. 
--------------------------
Comment:: That quadratic has minimum depth value but no maximum depth.
The maximum depth should be at the middle of the lake and the radius
of the lake could be determined.  Did you post the quadratic correctly?
Cheers,
Stan H.
