the relationship between the relative size of an earthquake, S, and the measure of the earthquake on the Richter scale, R, is gi

omeli [17]

Answer:

Relative Size, S, is 1584.89

Step-by-step explanation:

The equation is $R=log_{10}(S)$

Where,

R is the measurement in Richter Scale
S is the relative size of the earthquare

<u>It is given that in Richter Scale, an earthquake measured 3.2, so $R=3.2$ .</u>

<em>They want to know relative size, S, so we put given information in equation and solve for S:</em>

$R=log_{10}(S)\\3.2=log_{10}(S)$

<em>Converting to exponential form, we have:</em>

$3.2=log_{10}(S)\\S=10^{3.2}\\S=1584.8932$

<em>Rounding to nearest hundredth, we have:</em>

$S=1584.89$
