4. Sig Figs State how many significant figures are proper in the results of the following calculations: (106.7) (98.2) a. (46.210) (1.01) b. (18.7) 2 c. (1.60 x 10 19) (3712) 5. Geometric Vector Manipulation For the vectors given in the figure below, use a graphical method (use ruler and protractor to earn full credit) to find the following resultants and double check your work using algebraic expressions for the vectors. A - 8.661 + 5.003, B - 3.017 + 3.993. C - 6.002 -10.43, D - -16.02 + 12.03, F --17.32 10.03 a. A + B 60 b. C + B C = 120 A A -10.0 C. D - F 30 d. C - 2D + 3F 30 F = 20.0 F B = 5.0 D D = 20.0 37"
