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

n(t)=-3t^+23t^2=8t Rewrite the formula by factoring the right-hand side

completely.

b) Use the factored version of the formula to find N(3) maximum number of components assembled

-3t^3 + 23t^2+8t

-t(3t^2-23t-8)

-t(3t+1)(t -8)

check that.
