The addition of technologies to the industrial production system aims to reduce costs and increase productivity. In the first year of operation, a company manufactured 8,000 units of a certain product. The following year, it invested in technology by acquiring new machines and increased production by 50%. It is estimated that this percentage increase will be repeated in the following years, ensuring an annual growth of 50%. Consider P as the annual quantity of products manufactured in year t of the company's operation. If the estimate is reached, what is the expression that determines the number of units produced P as a function of t, for t greater than or equal to 1? A) P(t) = 0.5 · t1 + 8,000 B) P(t) = 50 · t1 + 8,000 C) P(t) = 4,000 · t1 + 8,000 D) P(t) = 8,000 · (0.5)t - 1 E) P(t) = 8,000 · (1.5)t - 1 Matemática Rio is a channel with online math classes, totally free and creative!
