Question 907071: Urgent please help!
What is the depth of the photic zone of this lake? SOLVE for x
l/l_0 = 0.01 so,+0.01+=+e%5E%28-0.025%28x%29%29 please round the answer to one decimal place.

You can put this solution on YOUR website!
l/l_0 = 0.01 so,+0.01+=+e%5E%28-0.025%28x%29%29
-------------
+0.01+=+e%5E%28-0.025%28x%29%29
Get the log of both sides
ln(0.01) = -0.025x
x = -ln(0.01)/0.025
x =~ 184.2 feet
