Um automóvel está a uma velocidade 2c em uma rodovia. Sabendo que 2c é metade da velocidade máxima permitida nessa rodovia, assinale a alternativa: * 2 pontos A. Como velocidade e tempo gasto no percurso são grandezas diretamente proporcionais, se a velocidade do automóvel for 4c, ele gastará o dobro do tempo no percurso. B. Se a velocidade do carro for igual à velocidade máxima permitida na rodovia, o automóvel percorrerá o dobro da distância que seria capaz de percorrer na velocidade inicial. C. Quando a velocidade do automóvel for igual a c, sua velocidade será igual à velocidade máxima da rodovia. D. As grandezas velocidade e distância percorrida são inversamente proporcionais. E. As grandezas velocidade e tempo gasto no percurso são diretamente proporcionais.

Evaluate 8x2 + 9x − 1 2x3 + 3x2 − 2x dx. solution since the degree of the numerator is less than the degree of the denominator, we don't need to divide. we factor the denominator as 2x3 + 3x2 − 2x = x(2x2 + 3x − 2) = x(2x − 1)(x + 2). since the denominator has three distinct linear factors, the partial fraction decomposition of the integrand has the form† 8x2 + 9x − 1 x(2x − 1)(x + 2) = correct: your answer is correct. to determine the values of a, b, and c, we multiply both sides of this equation by the product of the denominators, x(2x − 1)(x + 2), obtaining 8x2 + 9x − 1 = a correct: your answer is correct. (x + 2) + bx(x + 2) + cx(2x − 1).
