Año de introducción:
1. Tener la especialidad de Habilidad matemática III
2. Presentar un informe bibliográfico con por lo menos cinco personalidades que contribuyeron al desarrollo de la matemática a lo largo de la historia de la humanidad.
3. Desarrollar y presentar los cálculos de las siguientes ecuaciones:
- a. 5x² - 3x - 2 = 0
- b. 3x² + 55 = 0
- c. x² - 10x + 25 = 0
4. Presentar y desarrollar los cálculos de porcentaje de los siguientes problemas:
- a. 3% of 450
- b. 25% of 1440
- c. 30% of 2500
5. Present three practical situations, in written form, of situations in which we use percentages in our daily routine.
6. Present and develop three practical situations of everyday problems in which we use the quadratic equation.
7. Solve and present the development of the following functions, assuming that f(x) = x - 3 and g(x) = -3x + 4.
- a. f(f(0))
- b. f(f(1)) + g(f(3))
8. Represent the following functions in a Cartesian graph:
- a. y = 3x-1
- b. f(x) = 2x + 3
9. Demonstrate the ability to solve problems with circles; how to calculate the circumference and area using the formula for each. Present two examples of each.
10. Present the ability to calculate the area of regular polygons, such as a hexagon inscribed in a circle, area of a cylinder surface, volume of a prism, and the volume of a pyramid.
11. In our daily routine, we have to deal with all prices of tax rates. Demonstrate the ability to solve the two most common situations of interest.
- a. Luciana made an investment of $100 at 2% simple interest a month. How much will she have in total after 8 months of investing?
- b. David asked for a bank loan of $3000 and will pay in 6 months a composite interest rate of 1.5% a month. Calculate the total to be paid to the bank after 6 months.
