Dave and Sandy Hartranft are frequent flyers with a particular airline. They often fly from City A to City B, a distance of 828
miles. On one particular trip, they fly into the wind, and the flight takes 2 hours. The return trip, with the wind behind them, only takes 1 and 1/2 hours. If the wind speed is the same on each trip, find the speed of the wind and find the speed of the plane in still air.
After
using a calculator to find sin 21 degrees and rounding it to four decimal places,
I got 0.3584. The correct answer between all the
choices given is the first choice. I am hoping that this answer has satisfied
your query and it will be able to help you in your endeavor, and if you would
like, feel free to ask another question.
as the function is polynomial domain exist for all real number ie (-infinity to + infinity) but range exist (0 to +infinity ) due to modulus negetive range do not exist
