Write an equation in slope-intercept form of the line whose parametric equations are x= (1/2)t + (2/3) and y= t – (3/4).

Question

t = y + 3/4
x = 1/2(y + 3/4) + 2/3
2x = y + 3/4 + 4/3
2x = y + 25/12
y = 2x - 25/12

A force F1 of 35 newtons pulls at an angle of 15 degrees north of due east. A force F2 of 75 newtons pulls at an angle of 55 degrees west of due south. Find the magnitude and direction of the resultant force.

43.8 N, 39.1 degrees west of due south.
