Solve the problem.The farther someone is from a light source, the less intense its light. The equation I = approximates the light intensity from a certain light source at a distance of d meters, where I is measured in watts per square meter. Find I for d = 2 meters and interpret the result.

Question

A.  = 6.25; the intensity is 6.25 W/m² at 2 m.
B.  = 25; the intensity is 25 W/m² at 2 m.
C.  = 12.5; the intensity is 12.5 W/m² at 2 m.
D.  = 1.5625; the intensity is 1.5625 W/m² at 2 m.

Answer 1

Answer: D
