The number of research articles in a prominent journal that were written by researchers in Europe can be modeled by P(t) P 7r 6 5 4 3 2 1 0 0 10 t = Graph of P 20 30 x X t 40 What does the point of inflection tell you about science articles? From the graph of P' we see that P' has a maximum at around t = X P 0.20 x 0.15 0.10 0.05 0.00 0 10 Graph of P 20 = 30 7.0 1 + 5.4(1.2) 1/2' t 40 Ⓡ where t is time in years. The graphs of P, P', and P" are shown here. p" 0.010 Determine to the nearest whole number the values of t for which the graph of P is concave up and where it is concave down, and locate any points of inflection. concave up 0 concave down <t< <t< point of inflection 0.005 0.000 -0.005 -0.010¹ 10 Graph of P" 20 30 x, meaning that the number of articles written by researchers in Europe was increasing most rapidly at around t = t 40 Enter a number.
