Introdução ao estudo das máquinas térmicas

A eficiência do motor de um automóvel é igual a 30%. Se o combustível que consome tem uma energia de 35.000 \text{ KJ/kg}, qual é a quantidade de energia mecânica (trabalho útil) que o motor transforma com 1 \text{ kg} de combustível?

Divide el polinomio p(x) = 3x^4 + 4x^3 + x^2 entre el polinomio q(x) = 2+x. Como el polinomio divisor, q(x), es de grado 2, debemos encontrar dos polinomios, un polinomio cociente (c(x)) y un polinomio resto (r(x)) de grado 1 o 0, tales que p(x) = q(x) * c(x) + r(x).

El polinomio p(x) es de grado 4.

El polinomio q(x) es de grado 1.

El polinomio cociente c(x) es de grado 2.

El polinomio resto r(x) es de grado 1 o 0.
