Answer

Answer:

A. 0.135

Explanation:

Step1: Recall the value of e

The base of the natural - logarithm, (e\approx2.71828).

Step2: Calculate (e^{- 2})

The formula for (a^{-n}=\frac{1}{a^{n}}), so (e^{-2}=\frac{1}{e^{2}}). Using a calculator, (e^{2}\approx7.38906), then (e^{-2}=\frac{1}{7.38906}\approx0.135).
