4. A team searching for ship wrecks in Lake Superior has used sonar to map the depth of the lake floor and has developed the model D = 250 + 30x + 50 sin 7,0 x 2,0 y 2 where D is depth in feet and x and y are distances in miles. a. What is the depth of the ship if it is located at (1,0.5)? b. Determine the steepness of the ocean floor in the positive x direction from the position of the ship. C. Determine the steepness of the ocean floor in the positive y direction from the position of the ship. d. If you sent a diver to the bottom, from which direction would they not want to walk towards the ship (find the direction that will have the steepest approach)? 4.
