The rate (per foot) at which light is absorbed as it passes through water is proportional to the intensity, or brightness, at that point. A) Find the intensity as a function of the distance the light has traveled through the water. l is intensity, s is the distance traveled through the water, k>0 is the proportionality constant, and A represents the initial intensity of the light. l(s)=?B) If 20% of the light is absorbed in 10 feet, how much is absorbed in 20 feet? and 25%?round answer to 1 decimal place.

(01.03 mc) which of the following is a step in simplifying the expression x multiplied by y to the power of 2 over x to the power of negative 3 multiplied by y to the power of 3, the whole to the power of negative 4. select one: a. x to the power of negative 4 multiplied by y to the power of negative 2, the whole over x to the power of negative 7 multiplied by y to the power of negative 1. b. x to the power of negative 4 multiplied by y to the power of negative 8, the whole over x to the power of 12 multiplied by y to the power of negative 12. c. x to the power of negative 4 multiplied by y to the power of negative 8, the whole over x to the power of negative 3 multiplied by y to the power of 3. d. x to the power of negative 4 multiplied by y to the power of negative 2, the whole over x to the power of negative 3 multiplied by y to the power of 3.
