Concept explainers
(Modeling) Measuring Rainfall Suppose that
V= |R · A|.
This formula calculates the volume of water collected even if the wind is blowing the rain in a slanted direction or the rain gauge is not exactly vertical. Let R = i - 2j and A = 0.5i + j.
(a) Find | R | and | A | to the nearest tenth. Interpret the results.
(b) Calculate V to the nearest tenth, and interpret this result.
