What is one difference between fixed-rate mortgages and variable-rate mortgages?

One difference between fixed-rate mortgages and variable-rate mortgages is that the interest rate can vary. A fixed-rate mortgage carries less risk because the rate cannot change. A variable-rate mortgage can seem cheaper in the beginning, but is often more expensive over the life of the loan.

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
