We have that <span>Log3 a/3 </span>Rewrite log3(a/3) using the change of base <span>formula
we know that </span>The change of base rule can be used if a and b are greater than 0 and not equal to 1, and x is greater than 0<span>. </span>so loga(x)=<span>logb(x)/<span>logb<span>(a) </span></span></span>Substitute in values for the variables in the change of base <span>formula </span> in this problem b=10 a=3 x=a/3
If you were making a replica ferris wheel it would be similar to the larger ferris wheel. This means that all the angles would be the same. If the angles were the same, the arc measures would also be the same.
