4 x e (d) dy dx y tan x. Solve the following ivp problems. (a) dy y dx. 2: it is known that a certain object has constant of proportionality. 0 f, it is placed in a medium whose temperature is changing in time according to tt m. 20: using newton"s law of cooling, determine the temperature of the object at time t, what happens to the temperature of the object as. Is it reasonable: using ero (elementary row operations) to reduce the given matrix to rref (reduced row echelon matrix). Then determine the rank of the matrix: determine the solution set to the give. = - 3. n system of equations: determine all values of the constant k for which the following system has (a) no solution , (b) an infinite number of solutions, and (c) a unique solution. x. 7, k: find (if it exists) the inverse of each of the given matrices by using the gauss-jordan method.
