Write a method called dangerousDescent that determines whether there is a downhill section in the hiking trail with a gradient of more than -5%. The gradient is calculated by the rise in elevation over the run in distance. For example, the last kilometer section has a gradient of -1% because the rise in elevation is 40 - 50 = -10 meters. The distance covered in 1000 meters. -10 / 1000 = -1%.

Your method should return true if there exists a dangerous descent in the given array, false otherwise.

Working on this program in python 3.7: a year in the modern gregorian calendar consists of 365 days. in reality, the earth takes longer to rotate around the sun. to account for the difference in time, every 4 years, a leap year takes place. a leap year is when a year has 366 days: an extra day, february 29th. the requirements for a given year to be a leap year are: 1) the year must be divisible by 42) if the year is a century year (1700, 1800, the year must be evenly divisible by 400some example leap years are 1600, 1712, and 2016.write a program that takes in a year and determines whether that year is a leap year.ex: if the input is 1712, the output is: 1712 is a leap year. ex: if the input is 1913, the output is: 1913 is not a leap year. your program must define and call the function isleapyear(useryear). the function should return true if the input year is a leap year and false otherwise.
