A bird flies from tree P to another tree Q which is 50m on a bearing of 030 degrees from P from Q the bird flies 80m due west to another tree R and finally flies due south to another tree S which is on a bearing of 120 degrees from P. (A) Using the scale 1cm=10m, construct an accurate scale drawing showing the positions of P, Q,R and S.
(B)By measurement from your scale drawing determine
(i)The distance and bearing of R and Q
(ii) The distance from S and P

Which graph has a rate of change of zero

Common binomial factor of 6x(3x+7)+5(3x+7)

I've been working on this for a few days and i just don't understand, it's due in a few hours. you.the direction of a vector is defined as the angle of the vector in relation to a horizontal line. as a standard, this angle is measured counterclockwise from the positive x-axis. the direction or angle of v in the diagram is α.part a: how can you use trigonometric ratios to calculate the direction α of a general vector v = < x, y> similar to the diagram? part bsuppose that vector v lies in quadrant ii, quadrant iii, or quadrant iv. how can you use trigonometric ratios to calculate the direction (i.e., angle) of the vector in each of these quadrants with respect to the positive x-axis? the angle between the vector and the positive x-axis will be greater than 90 degrees in each case.part cnow try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
