Suponha que a expressão P = 100 + 20 cos(2π t) descreve de maneira aproximada a pressão sanguínea P, em milímetros de mercúrio, de uma certa pessoa durante um teste. Nessa expressão, t representa o tempo em segundos. A pressão oscila entre 20 milímetros de mercúrio acima e abaixo dos 100 milímetros de mercúrio, indicando que a pressão sanguínea da pessoa é 120 por 80. Como essa função tem um período de 1 segundo, o coração da pessoa bate 60 vezes por minuto durante o teste. Calcule o valor da pressão sanguínea dessa pessoa quando t = 0 seg. 100 mm de Hg
80 mm de Hg
1000 mm de Hg
10 mm de Hg
