Kathy and Jake are purchasing a house and are financing $465,000. The mortgage is a 20-year 5/1 ARM at 3.5% with a 2/7 cap structure. What will the remaining balance be after the first 5 years?

what are ur choices?

you can't solve x because it is 2 linear equation and you only have one equation

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
