Aforce of 8 n makes an angle of π/4 radian with the y-axis, pointing to the right. the force acts against the movement of an object along the straight line connecting (1, 3) to (4, 5).
a. find a formula for the force vector f
b. find the angle θ between the displacement direction d = (4 − 1)i + (5 − 3)j and the force direction f. (round your answer to one decimal place.)
c. the work done is f · d or, equivalently, ||fd||cos(θ). compute the work from both formulas and compare

Three numbers x, y, and z are in the ratio 2: 7: 8. if 12 is subtracted from y, then three numbers form a geometric sequence (in the order x, y–12, z). find x, y, and z. there are 2 sets.
