The earth revolves around the sun in exactly 365 1/4 days which is equivalent to 1 year. To make up for the loss of 1/4 day, the calendar was adjusted so that we have a leap year for every 4 years. If the earth were to speed in its motion slightly so that a year would be completed in exactly 365 days and 6 hours, how often would we need to have a leap year?
What would be the duration of the year,
if the distance between the earth and the sun
gets doubled ?
(a) 129 days
(b) 365 days
(c) 556 days
(d) 1032 dayş
The number of hours of daylight in Boston is given by y=3sin [2π(x - 79)/365] + 12, where x is the number of days after January 1. Solve, Within a year, when does Boston have 13.5 hours of daylight? Give your answer in days after January 1 and round to the nearest day.
