An optimization specialist studied a factory's existing processes and work-flow to implemented new equipment and updated production processes. After the new equipment and processes were in place, he studied the production and modeled the productivity with the following function: P(t) = − 4t³ + 108t² + t, where t is the number of hours worked in a 10-hour shift. Find the point of diminishing returns for this factory. The point of diminishing returns is at t =

An optimization specialist studied a factory's existing processes and work-flow to implement new equipment and updated production processes. After the new equipment and processes were in place, he studied the production and modeled the productivity with the following function:

\[ P(t) = -4t^3 + 108t^2 + t \]

where \( t \) is the number of hours worked in a 10-hour shift. Find the point of diminishing returns for this factory.

The point of diminishing returns is at \( t = \) [ ]
