Answer:
If it is [tex]p(x)=\frac{90}{(9+50e^{-x})}[/tex], then: [tex]p(3)=7.83[/tex]
If it is [tex]p(x)=\frac{90}{9}+50e^{-x}[/tex], then: [tex]p(3)=12.48[/tex]
Step-by-step explanation:
To solve this exercise you must substiute x=3 into the expression given in the problem.
1) If the expression is [tex]p(x)=\frac{90}{(9+50e^{-x})}[/tex], you obtain:
[tex]p(3)=\frac{90}{(9+50e^{-(3)})}[/tex]
[tex]p(3)=7.83[/tex]
2) If the expression is [tex]p(x)=\frac{90}{9}+50e^{-x}[/tex], you obtain:
[tex]p(3)=\frac{90}{9}+50e^{-(3)}\\p(3)=12.48[/tex]
