Question

Answer gets BRAINLIEST If q varies inversely as r, and g = 10 when r = 2.5, find the equation that connects a

Answer 1

Answer:

D.

Step-by-step explanation:

In direct variations, we would have:

$q=kr$

Where k is some constant.

Since this is indirect variation, instead of that, we would have:

$q=\frac{k}{r}$

To determine the equation, find k by putting in the values for q and r:

$10=\frac{k}{2.5}\\k=2.5(10)=25$

Now plug this back into the variation:

$q=\frac{25}{r}$

The answer is D.
