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 righthand 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 righthand 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^223t8)
t(3t+1)(t 8)
check that.
