Question
If interstellar dust makes an RR Lyrae variable star look 7 magnitudes fainter than the star should, by how much will you over- or underestimate its distance? (*Hint: Use the magnitude-distance formula \( d = 10^{(m_V - M_V + 5)/5} \).) \[ \frac{d_{\text{estimate}}}{d_{\text{actual}}} = \text{[input box]} \] Is your calculated value an over- or underestimate? - ○ overestimate - ○ underestimate
