- A helicopter pilot needs to travel to a regional airport 25 miles away. She flies at an actual heading of N16.26°E with an airspeed of 110 mph, and there is a wind blowing directly east at 20 mph. (a) Determine the compass heading that the pilot needs to reach her destination. (b) How long will it take her to reach her destination?arrow_forwardhelp me with ab please. please handwrite if possible. please don't use AI tools to answerarrow_forwardQuestion 3. the given integral is convergent or divergent: Use the comparison test to determine whether or not * sin*(x + 1) 7x3 (a) |. d.x g8 + x4 + 1 -dx (b) 2.x4 + x + 1arrow_forward
