On the grid, graph a line to represent the total cost, y, of a
Brand C bottle with sounces. Graph a second line to
represent the total cost of a Brand S bottle. Use the Line
tool.

answer: i think it is (1,-2)

i saw this question before, dont know the asnwer srry

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
