- Let f(.) be a twice differentiable function from \(\R^2\rightarrow\R\). If p, x0 ∈ \(\R^2\) where ||p|| is sufficiently small (here ||. || is the Euclidean norm or distance function), then \(f(x_0 + p) =f(x_0) + \triangledown f(x_0)^Tp+\frac{1}{2}p^T\triangledown^2f(\psi)p\) where \(\psi\isin\R^2\) is a point on the line segment joining x0 and x0 + p. If x0 is a strict local minimum of f(x), then which one of the following statements is TRUE?

- A 2m × 2m tank of 3 m height has inflow, outflow and stirring mechanisms. Initially, the tank was half-filled with fresh water. At t = 0, an inflow of a salt solution of concentration 5 g/m3 at the rate of 2 litre/s and an outflow of the well stirred mixture at the rate of 1 litre/s are initiated. This process can be modelled using the following differential equation:
\(\frac {dm}{dt}+\frac {m}{6000+t}=0.01\)
where m is the mass (grams) of the salt at time t (seconds). The mass of the salt (in grams) in the tank at 75% of its capacity is _____ (rounded off to 2 decimal places).- GATE CE - 2024
