Plzz help 1. Use a power function to describe the relationship between the planets' orbital period around the sun and the half major axis??

I have made the power function.

2. Use the power function to calculate the half major axis of the asteroid Vesta, which has an orbital period around the sun of 3.63 years??

Some tings i wrote down:

I have to use keplers law: Kepler's laws say that: T^2 / a^3 = constant

y=1.00027*x^1.499

1.499 same as 1.5 same as 3 halfs

y = t is that year depends on the radius of AE

We use an AE on the ground which is 1 and a 1 year on the ground is 1
