Este é um problema de juros simples, que é calculado pela fórmula: I = Prt onde I são os juros, P é o principal, r é a taxa e t é o tempo. Seja P o capital inicial er a taxa anual. Então, de acordo com as informações fornecidas, temos: 6600 = P + P \vezes r \vezes \frac{27}{12} e 6600 + 0,0075P = P + P \vezes r \vezes \frac{28}{12} Resolvendo essas duas equações simultaneamente, obtemos: P = 5488.56548 e r = 0,9 Portanto, o capital inicial foi de 5.488,57 um e a taxa anual foi de 9%.

A company is wondering whether to invest £18,000 in a project which would make extra profits of £10,009 in the first year, £8,000 in the second year and £6,000 in the third year. It’s cost of capital is 10% (in other words, it would require a return of at least 10% on its investment). You are required to evaluate the project.

User One of the applications of the derivative of a function is its use in Physics, where a function that at every instant t associates the number s(t), this function s is called the clockwise function of the movement. By deriving the time function we obtain the velocity function at time t, denoted by v(t). A body has a time function that determines its position in meters at time t as S(t)=t.³√t+2.t . Present the speed of this body at time t = 8 s.
