Question

The variables x and y satisfy the equation y n = ax3 , where n and a are constants. It is given that y = 2.58 when x = 1.20, and y = 9.49 when x = 2.51.

Answer 1

Answer:

n/a = 67/100 , 167/100

Step-by-step explanation:

yn = ax³ --- given

Therefore, n/a = x³/y

Case 1:

When  y = 2.58 when x = 1.20

n/a = 1.2³/2.58 = 1.728/2.58 = 0.669 = 67/100

Case 2:

When y = 9.49 when x = 2.51.

n/a = 2.51³/9.48 = 1.668 = 167/100
