Question

The number of watches for a video in thousands per month is modeled by 5te^((-t^2)/50), where t represents the number of months since the video was first posted. Calculate how many views it would get in thousands during its first 10 months of being posted.

Answer 1

∫[0,10] 5te^((-t^2)/50) dt = -125e^((-t^2)/50) [0,10] = 125(1 - 1/e^2) ≈ 108
