Step-by-step explanation:
THE DIVISION of the hour into 60 minutes and of the minute into 60 seconds comes from the Babylonians who used a sexagesimal (counting in 60s) system for mathematics and astronomy. They derived their number system from the Sumerians who were using it as early as 3500 BC.
B. This quadratic is a negative on the y axis
11:32 pm + 5 hours= 4:32pm
4:32 pm + 45 minutes = 5:17 pm
3/4 hour = 45 min
Answer: The discriminant is the part of the quadratic formula underneath the square root symbol: b²-4ac. The discriminant tells us whether there are two solutions, one solution, or no solutions.
