QUESTION 38 "Mediocre economists often consider only the immediate apparent effects of a change, whereas a good economist will also consider effects that may only become observable over time." This statement most clearly emphasizes a. the fallacy of composition. b. economizing behavior. c. the importance of secondary effects. d. the fact that association is not causation.

One aspect of digital transformation is adopting Artificial Intelligence (AI) in business processes. However, AI is not without problems. Discuss ANY THREE (3) organisational risks as well as ANY TWO (2) customer risks associated with AI.

Esercizio 17.2 Sia \( F \) l'endomorfismo di \( \mathbb{R}^{3} \) associato alla matrice \( A=\left(\begin{array}{ccc}1 & -3 & 1 \\ -3 & -2 & 0 \\ 1 & 0 & -2\end{array}\right) \) rispetto alla base canonica. (4) Scrivere l'espressione generale di \( F \). (i) Usando la definizione data, verificare che \( F \) è un endomorfismo simmetrico. (iii) Diagonalizzare \( F \) rispetto ad una base ortonormale di \( \mathbb{R}^{2} \) di autovettori per \( F \).

Topological space. Let \( X=\{a, b, c, d, e\} \) and \( T=\{\phi, X,(a),\{b\},\{a, b\},(c),(a, b, c),\{a, c),\{b, c)\} \), Let \( E=(a, b \) (s). Find the closure and interior of \( E \)

Problema A.1. Dadas las matrices cuadradas \[ I=\left(\begin{array}{lll}1 & 0 & 0 \\ 0 & 1 & 0 \\ 0 & 0 & 1\end{array}\right) \quad \text { y } \quad A=\left(\begin{array}{rrr}2 & 1 & 1 \\ 2 & 3 & 2 \\ -3 & -3 & -2\end{array}\right) \text {, } \] se pide: a) Calcular las matrices \( (A-I)^{2} \) y \( A(A-2 I) \). (4 puntos). b) Justificar razonadamente que b.1) Existen las matrices inversas de las matrices \( A \) y \( A-2 I .(2 \) puntos). b.2) No existe matriz inversa de la matriz \( A-I \). (2 puntos). c) Determinar el valor del parámetro real \( \lambda \) para el que se verifica \( A^{-1}=\lambda(A-2 I) \quad(2 \) punt
