Not a function.
Step-by-step explanation:
The given function is;
Let 
Interchange x and y;
Solve for y;
Square both sides
The inverse is
is not a function because one x-value maps onto to different y-values.
Answer:
cos r/q is the answer,
Step-by-step explanation:
this can be seen when you elaborate sin=opposite/hypotenus and tan=opposite/adjacent by referring to the right angle triangle .
then, apply values of adjacent dan hypotenuse to cos
Let the numbers be x and y.
by the first statement of the question, we get , x + y = 30.,,..(1)
by the second satement, we get , x = y+ y => x=2y... (2)
from equation (2), let us put the value of x in equation (1),
x + y = 30
=> 2y + y = 30
=> 3y = 30
=> y =30/3
=> y = 10
and x=2y => x = 2*10 = 20
in short, the numbers are 10 and 20
