Parameter after one SGD step on a linear objective

Consider that for a supervised learning task, the objective function being minimized is fw(x)=wxf_w(x) = wx, where x∈Rx \in \mathbb{R} is the input and w∈Rw \in \mathbb{R} is the parameter. Stochastic Gradient Descent with learning rate of 0.10 is used for parameter updates. Suppose that at the end of iteration ii, the value of ww becomes 10.00. Let x=10.00x = 10.00 be the input for iteration (i+1)(i+1). The value of ww at the end of iteration (i+1)(i+1) is __________ . (Rounded off to two decimal places)

Numerical answer: type the number (no options).

Type your answer and check it.
