Financial Calculations Exercises
1 .- Telefónica bought shares late last year to 15.85 euros. Today, two and a half months later, is trading at 14.14 euros. What is the compound annual percentage rate on my investment?
a) -10.79%
b) -2.35%
C) -42.19%
d) -51.79%
We just have to replace the formula under the composite type, expressing the time in years:
14.14 = 15.85 * (1 + i) ^ (2.5/12), and therefore po, i = (14.14/15.85) ^ (12/2.5) -1 =- 0.42188
2 .- A commercial paper maturing in 175 days, with a nominal value of 1500 euros,

Econometrics: Models, Variables, and Parameters
Econometrics
Econometrics combines mathematical and economic theory to build econometric models.
Model Theory
1. Models
A model is a simplified representation of economic reality, expressed in mathematical terms.
2. Requirements of Models
- Represent economic reality
- Have supporting theoretical content
- Be a simplified representation
- Be expressed mathematically
3. Elements of a Model
A model consists of three elements:
Where:
- Y = Endogenous variable
- x = Predetermined variable
- a = Intercept parameter
- b = Slope parameter
- ε
Understanding Social Networks: A Comprehensive Overview
1. Definition of Social Networks
Social networks are forms of social interaction, defined as a dynamic exchange between individuals, groups, and institutions in complex contexts.
2. Social Networking Features
Social networks are open and continuously evolving, involving groups with shared needs and problems, organized to leverage their resources. Their purposes are varied but non-profit, ranging from connecting with classmates, friends, and relatives to fostering professional relationships and business

Understanding Mathematical Functions and Their Properties
Functions
A function, as defined by Laplace, is a law that associates each value of the independent variable x with a value of the dependent variable y. This correspondence can be written as:
A function is said to be injective if each element of the domain (set A, represented by x) maps to a unique element of the codomain (set B, represented by y). This is also known as a one-to-one correspondence.
A function is surjective if every element of the codomain (B) is an image of an element in the domain
