Determine the domain of the function.

f(x)=√1·x
a. all real numbers
b. x> 1
c. x≤1
d. all real numbers except 1

answer: you need to organize this better it does not make sense.

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

      2

  2 is to go somewhat to the top right of a because it is squared    

v= a h/3
