(b) Use a trapezoidal sum with the four subintervals given by the table to approximate the value of - E(t) dt. 8 Jo Using correct units, explain the meaning of E(t) dt in terms of the number of entries. 8 Jo (c) At 8 P.M., volunteers began to process the entries. They processed the entries at a rate modeled by the function P, where P(t) = r³ – 30z² + 298t – 976 hundreds of entries per hour for 8 < t < 12. According to the model, - how many entries had not yet been processed by midnight (t = 12) ? (d) According to the model from part (c), at what time were the entries being processed most quickly? Justify your answer.

A zoo sponsored a one-day contest to name a new baby elephant. Zoo visitors deposited entries in a special box
between noon (t = 0) and 8 P.M. (t = 8). The number of entries in the box t hours after noon is modeled by a
differentiable function E for 0 <t< 8. Values of E(t), in hundreds of entries, at various times t are shown in
the table above.
