Meghan and Dominic do their math homework together. When they find 7−​(−9​), they get different answers. Meghan claims the difference is 2. Dominic claims the difference is 16. Who is​ correct? What error likely led to the incorrect​ difference? ( ignore the Wattpad and tumblr‍)

c - they will have the same distribution

step-by-step explanation:

this is the only one that could make sense. : )

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
