A dolphin is swimming with her friend. The dolphin jumps to a height of 4.5 meters above the surface of the
water as her friend swims 9.8 meters directly below her.
What is the position of the dolphin's friend relative to the surface of the water?

14.3 meters

Step-by-step explanation: Since her friend is 9.8 meters below her, and she is 4.5 meters below the surface of the water, add up the two depths. 9.8+4.5=14.3.

The answer for this equation is -5.3

Step-by-step explanation: The question states that a dolphin is swimming with her friend. The dolphin jumps to a height of 4.5 meters above the surface of the water as her friend swims 9.8 meters directly below her.

The surface of the water is 0 and the dolphin jumped to a height of 4.5 meters above the surface of the water. Making 4.5 a positive, and her friend swam 9.8 meters directly below her making 9.8 a negative.

So the equation of this would be 4.5 + (-9.8) or 4.5 - 9.8
