So the answer would be A = πr 2 because we are talking about area
log₉(<em>x</em> - 7) + log₉(<em>x</em> - 7) = 1
2 log₉(<em>x</em> - 7) = 1
log₉(<em>x</em> - 7) = 1/2
Take the base-9 antilogarithm of both sides; in other words, make both sides powers of 9:
can also be written as √9 = 3, and , so the equation reduces to
<em>x</em> - 7 = 3
Solve for <em>x</em> :
<em>x</em> = 10
I think it’s between 100-200 like 150 cause it’s near a 100 and more then a 100 too.
It means that the data is more self centered to a certain side.
