4) From A, B lies 11 km away on a bearing of 0410 and C lies 8 km away on a bearing of 3410. Find

a) The distance between B and C.

b) The bearing of B from C.

F(x)=3x+3y+sinxy+cosxy

A car drives 15 km on a bearing of 114 degrees from P to Q. It then changes direction and drives 18 km on a bearing of 329 degrees from Q to R.find the distance between P to R

David and Emily are climbing El Capitan, a big cliff wall in Yosemite National Park. David is on the ground holding the rope attached to a carabiner (a rope “pulley” that is on the wall) above Emily as she climbs. When Emily stops to rest, David wonders how high she has climbed. The rope is attached to his waist, about 3 feet off the ground, and he has let out 48 feet of rope which goes up to the carabiner and then back down the wall to Emily’s harness. The rope at David’s waist makes a 55° angle with the ground and he is standing 20 feet away from the base of the wall.
Assuming that the rope is taut (pulled tight), approximately how long is the rope between David and the carabiner above Emily?

How high up the wall has Emily climbed? Describe your method.
