Adolphin is 40 feet below the surface of the water she rises 23 feet sinks 17 feet and finally rises another 27 feet if there is no other changes where is the dolphin located

The dolphin is located 7 feet below the surface

Step-by-step explanation:

Step 1

Determine the reference point

The reference point is at water surface=0 feet

Step 2

The location of the dolphin 40 feet below the surface can be expressed as;

Initial location=0-40=-40 feet

Step 3

The location after rising 23 feet, means it is moving towards the surface. This can be expressed as;

Location 1=Initial location+distance of rise

Location 1=-40+23=-17 feet or 17 feet below the surface

Step 4

The location after sinking 17 feet below location 1 can be expressed as;

Location 2=-17-17=-34 or 34 feet below the surface

Step 5

The final location after the dolphin rises another 27 feet can be expressed as;

final location=location 2+27 feet

final location=-34+27=-7 feet or 7 feet below the surface

The dolphin is located 7 feet below the surface

it would be 6xy and -16xy.

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
