Question 1128143
<br>
I assume the last "^" is not supposed to be there....<br>
And you DO need parentheses.  The logistic equation is NOT<br>
{{{P(t) = 1700/1 + 9e^-0.8t}}}<br>
The equation is (I assume!)<br>
{{{P(t) = 1700/(1 + 9e^-0.8t)}}}<br>
As for finding the answer, YOU need to use YOUR graphing calculator.  Graph the logistic function and the constant function 900 and find the x value where they intersect.
