Given the position function x (t) = t^4 - 8t², find the distance that the particle travels at t = 0 to t = 4. A. 140 C. 130 B. 150 D. 160 26. Planned water depth is considered as follows: (For a ship with draft of 7.5m) A. Standard water depth of berth for the ship (5.5m) + Design low tide (0.55m) = 6.05m B. Standard water depth of berth for the ship (-5.5m) + Design low tide (-0.55m) = -6.05m C. Standard water depth of berth for the ship (-7.5m) + Design low tide (-0.35m) = -7.85m D. Standard water depth of berth for the ship (7.5m) + Design low tide (0.35m) = 7.85m 27. One thousand copper rods have the properties shown in the following table.
