Answer

The distance between Venus and the sun is $ 0.7 $ astronomical unit.

Work Step by Step

The given formula is $ d=\frac{3(2^{n-2})+4}{10} $ Where, $ d $ is measured in astronomical units and $ n $ is the number of planet from the sun. Sustitute $ n=2 $ into the formula. $ d=\frac{3(2^{2-2})+4}{10} $ $ d=\frac{3(2^{0})+4}{10} $ $ d=\frac{3 \cdot 1+4}{10} $ $ d=\frac{ 3+4}{10} $ $ d=\frac{ 7}{10} $ $ d=0.7 $.
