GPT 3.5
b) a submarine at -340 feet under dives 340 feet
d) a dive at -40 feet under the sea rises 40 feet
In both of these situations, the two quantities combine to make 0.
For option b), we have -340 + 340 = 0. The submarine's depth is initially -340 feet, and then it dives 340 feet, which brings it back to the surface at 0 feet.
For option d), we have -40 + 40 = 0. The dive starts at a depth of -40 feet, and then rises 40 feet, bringing the diver back to the surface at 0 feet.
d) a dive at -40 feet under the sea rises 40 feet
In both of these situations, the two quantities combine to make 0.
For option b), we have -340 + 340 = 0. The submarine's depth is initially -340 feet, and then it dives 340 feet, which brings it back to the surface at 0 feet.
For option d), we have -40 + 40 = 0. The dive starts at a depth of -40 feet, and then rises 40 feet, bringing the diver back to the surface at 0 feet.
The answers I got were c, d, and e. Explain to me why c and e would not combine to make 0.
GPT 3.5
I apologize for the incorrect answer. You are correct, options c and e would also combine to make 0. Let's go through the calculations for options c and e.
For option c), we have 120 + (-120) = 0. The hawk is initially 120 feet above the ground and then dives 120 feet, bringing it back to the ground level at 0 feet.
For option e), we have -38 + 38 = 0. The octopus is initially at -38 feet underwater and then rises 38 feet, bringing it back to the surface at 0 feet.
So, the correct answers that combine to make 0 are: c) a hawk at 120 feet above the ground dives 120 feet, d) a dive at -40 feet under the sea rises 40 feet, and e) an octopus at -38 feet underwater rises 38 feet.
For option c), we have 120 + (-120) = 0. The hawk is initially 120 feet above the ground and then dives 120 feet, bringing it back to the ground level at 0 feet.
For option e), we have -38 + 38 = 0. The octopus is initially at -38 feet underwater and then rises 38 feet, bringing it back to the surface at 0 feet.
So, the correct answers that combine to make 0 are: c) a hawk at 120 feet above the ground dives 120 feet, d) a dive at -40 feet under the sea rises 40 feet, and e) an octopus at -38 feet underwater rises 38 feet.
Thank you, so you are saying ignore b and the answers are c, d, and e.....
GPT 3.5
Yes, I apologize for the confusion. The correct answers are c) a hawk at 120 feet above the ground dives 120 feet, d) a dive at -40 feet under the sea rises 40 feet, and e) an octopus at -38 feet underwater rises 38 feet. These are the situations where the two quantities combine to make 0. So, you can ignore option b).
