Question 57760: 104. 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).
please help thank you

N(t)= - 3t^3 + 23t^2 + 8t
a. Rewrite the formula by factoring the right hand side completely.
N(t)=t(-3t^2+23t+8)
----------------------------
b. Use the factored version of the formula to find N(3).
N(3)=3(-3(3^2)+23(3)+8)
N(3)=3(-27+69+8)
N(3)=3(50)
N(3)=150
