5.2.8. Suppose K1 and K2 are positive definite n × n matrices. Suppose that, for i = 1, 2, the minimizer of pi (x) = xTKix − 2xT fi + ci , is x i . Is the minimizer of p(x) = p1 (x) + p2 (x) given by x = x 1 + x 2 ? Prove or give a counterexample.

Q7 if you multiplying matrix K1 and K2.The number of items on the row of K1 must be equal to the number of items on the columns of matrix K2 if not it's not applicable.

Step-by-step explanation:

answer: he is 272195

step-by-step explanation: all you have to do is multiple 3535 and 77 and it equals 272195

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
