I believe the answer is C
Divide both sides by pir^2
h = v / pir^2 Answe
Answer:
b) x^4 varies directly as y
is the right answer
Step-by-step explanation:
Given that x and y are related by the equation
This can be rewritten as
If x^4 =z is substituted we have
z=7y
i.e. Z directly varies as y and constant of proportionality is 7.
Hence we can write
x^4 varies directly as y
Option b is right
Neutrons= Atomic Mass Number- Atomic Mass Number
So 85-25= 60
