For this case we have a direct variation of the form:

Where,
- <em>k: proportionality constant
</em>
We must find the value of k.
For this, we use the following data:

Therefore, replacing values we have:

Rewriting:

Clearing the value of k we have:

Therefore, the direct variation equation is given by:

Answer:
The quadratic variation equation for the relatonship is:

Answer:
I think it 1 but I may be wrong
