If point \(P\) is located \(\sqrt{0.04}\) units to the right of \(-0.4\), what is the value of \(P\)?

Answer and explanation

Correct answer: -0.2

First, \(\sqrt{0.04}=0.2\). Moving \(0.2\) units to the right on the number line means adding \(0.2\) to \(-0.4\): \(P=-0.4+0.2=-0.2\). Option A results from subtracting \(0.2\), which represents moving left instead. Exam tip: moving right increases the number, while moving left decreases it.
