Describe the vector as an ordered pair. Round the coordinates to the nearest tenth. Diagram is not drawn to scale. a. <-1.1, -4.9> b. <5.1, -22.2> c. <-4.9, -1.1> d. <22.2, -5.1>

b

step-by-step explanation:

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92

you could deduce the conclusion directly using the facts pertaining to the specific situation.

hope this .
