Question 1148896
<br>
I don't know how you can get the right answer for the second question without having the right answer for the first....<br>
(1) 5-day growth factor:
{{{15.1655/9}}}<br>
(2) 1-day growth factor:
5-day growth factor, to the (1/5) power.<br>
(3) 7-day growth factor:
1-day growth factor, to the 7th power, or 5-day growth factor, to the (7/5) power.<br>
Note your answer to the first question is reasonable, and close to the correct answer.  Maybe you punched in the wrong numbers on your calculator?<br>
Your answer to the third question is not reasonable.  If it grows from 9 inches to about 15 inches in 5 days, a growth factor of about 1.6, it's not going to grow by a factor of 11 in 7 days.  The answer should be something close to 2.<br>
