The answer is Radical 6.
This is because if you use Cosine and the angle measured 30. You would put adjacent over hypotenuse, which is
Cos (30) = X/radical 8
Put this into your calculator to get Radical 6
Answer:
domain: [-3,2]
range: [-3,2]
Step-by-step explanation:
domain: all possible x values *maximum values of x
range: all possible y values *maximum values of x
brackets means the max while parenthesis mean infinite

and also

now, we know that V varies directly to T and inversely to P simultaneously
thus

so
6z-7z/5=3
(30z-7z)/5=3
30z-7z=15
23z=15
z=15/23
