algebra
posted by samuala on .
can someone please help me with my algebra i got this as a answer and i don't know if its right.
N(t)= 3t^3 + 23t^2 + 8t
a. Rewrite the formula by factoring the righthand side completely.
N(t)= 3t^3 + 23t^2 + 8t
N(t)= (t)(3t^2  23t  8)
N(t)= (t)(3t+1)(t8)
b. Use the factored version of the formula to find N(3).
N(t)= (t)(3t+1)(t8)
N(3)= (3)(3(3)+1)(38)
N(3)= (3)(9+1)(5)
N(3)= (3)(10)(5)
N(3)= (15)(10)
N(3)= 150
C .the workers are most efficient in about 5 and a half hours because they make almost 250 components
d. The maximum number of components assembled per hour during a 8 hour shift is 1115 components.

a and b are correct, but I have no idea what you are talking about for c an d.
