Hilary and dale leave camp and go for a long hike. after going 7 km due east, they turn and go another 8 km in the direction 60 degrees north of east. they plan to return along a straight path. how far from camp are they at this point? use an angle to describe the direction that hilary and dale should follow to reach their camp.

Step-by-step explanation:

Given

First they travel 7 km east , then they go 8 km in direction 60^{\circ} north of east

Position vector of first point

Position vector of w.r.t to origin

magnitude of will give the distance they are from original point

direction

North of east

step-by-step explanation:

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
