Question 906984: Urgent I have tried everything I am not good with logarithms Please help.
This is question about Photic Zone.
The exponential function is I=Isub0e^-kx Isub0= 1000 foot candles so I=1000+%282.718282%5E%28-2.5%28x%29%29%29
depth of the water is x= depth in feet
What is the intensity of light at the depth of 10 feet? Round answer to one decimal place.

The exponential function is I=Isub0e^-kx Isub0= 1000 foot candles so I=1000+%282.718282%5E%28-2.5%28x%29%29%29
depth of the water is x= depth in feet
What is the intensity of light at the depth of 10 feet? Round answer to one decimal place.
------------------
I=1000+%282.718282%5E%28-2.5%28x%29%29%29
Sub 20 for x
I=1000+%28e%5E%28-25%29%29
I+=+1.4%2A10%5E-8
= 0.000000014 FC
