QuestionWhat function represents the world's population P (in billions) $t$ years after 1975, given a 1.9% growth rate? A) $P(t)=4(1.019)^{t}$ B) $P(t)=4(1.9)^{t}$ C) $P(t)=1.19 t+4$

Studdy Solution
implify the expression inside the parentheses$$(t) =4 \times (1.019)^t$$This function represents the world's population, in billions of people, t years since1975. Therefore, the correct answer is A) $(t)=4(1.019)^{t}$.
