1. ## I need HELP FAST!!!

questions are on attachment!

2. #1) Using the given info, $y=kz$ and $y=\frac{k}{\sqrt{r}}$ for some constant k. The question said that the constant of proportionality is the same for both and that this value is 10. Thus $y=10z$ and $y=\frac{10}{\sqrt{r}}$. You can solve each question using basic algebra from here.

I think the question is trying to say:

$
y=k\frac{z}{\sqrt{r}}
$

and that $k=10$.
