Answer:
C. 98.0%
Step-by-step explanation:
If t represents 35 days, then in order to find the daily decay rate we will have to input 1/35 as the value of t.
100(0.5)^ = 98.039
The daily decay rate is 98.0%

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
