D Question 3 7 pts The Following gives the rate of cost C' (t) where t is measure in weeks. If the initial costs come to $6000 find a function for the cost C(a) (round all values to two decimals) C' (x) = 2t(4t2 - 5)4 O C(x) = 20 (4t2 -5)5 + 6156.25 O C(x) = 2t(4t2 - 5)4 + 6000 O C(z)= (4t2 - 5)5 4 6000 O C(z) = =1? (4t2 - 5)5 + 6000
