Assignment:
Worker efficiency. In a study of worker efficiency at Wong Laboratories it was found that the number of components assembled per hour by the average worker t hours after starting work could be modeled by the formula N(t) = 3t^3 + 23t^2 +8t.
a) Rewrite the formula by factoring the right-hand side completely.
b) Use the factored version of the formula to find N(3).
Provide complete and step by step solution for the question and show calculations and use formulas.
