any one can solve my quetion

A neuron k receives input from other five neurons, as 0.5, 1, 0.25, -1.25 and -2. The corresponding synaptic weights are -0.7, 0.2, -0.4, -0.2 and 2.1. Assume the bias as -1.

Draw the computational model of neuron k.

Calculate the linear output of the neuron.

Find the output using Mc-Culloch Pitts model in activation function.

Find the output using Sigmoid function, whereas the slope parameter is 2.
