$3\mathrm{.}2$ Given a simple artificial neural network that does not have a hidden layer,

compute the output value given the following information:

There are $3$ inputs $(x1=30,x2=18,x3=-40)$ and the value of the bias $(b)$ is

$3$

The weights of the $3$ inputs are $+0\mathrm{.}35,+0\mathrm{.}21$ and $-0\mathrm{.}25$ respectively

$(10)$
