2. The pressure P of sound waves on a person's eardrum can be modeled by (2ar P = cos ( – 1100t) where a is the maximum sound pressure (in pounds per square foot) at the source, r is the distance (in feet) from the source, I is the length (in feet) of the sound wave, andt is the time (in seconds). Simplify this formula when r = 16 feet, I = 4 feet, and a = 0.4 pound per square foot.
