Question

Let p(x)=90/9+50e^-x What is p(3)

Answer 1

Answer:

p (3) = 7.83

Step-by-step explanation:

We are given the following expression and we are to evaluate it given that the value of $p = 3$:

$p ( x ) = \frac { 9 0 } { 9 + 5 0 e^ { - x } }$

Substituting the given value of $p$ to get:

$p ( 3 ) = \frac { 9 0 } { 9 + 5 0 e^ { - 3 } }$

$p ( 3 ) = \frac { 9 0 } { 11.489 }$

$p ( 3 ) = 7.83$

Answer 2

Answer:

If it is $p(x)=\frac{90}{(9+50e^{-x})}$, then: $p(3)=7.83$

If it is $p(x)=\frac{90}{9}+50e^{-x}$, then: $p(3)=12.48$

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 $p(x)=\frac{90}{(9+50e^{-x})}$, you obtain:

$p(3)=\frac{90}{(9+50e^{-(3)})}$

$p(3)=7.83$

2) If the expression is $p(x)=\frac{90}{9}+50e^{-x}$, you obtain:

$p(3)=\frac{90}{9}+50e^{-(3)}\\p(3)=12.48$
