Answer:
When p is 2, q is 10.
Explanation:
If p and q vary inversely, then their product remains constant. We can set up a proportion to solve the problem:
p * q = k, where k is the constant of variation.
When p is 5 and q is 4, we have:
5 * 4 = k
k = 20
So the equation that relates p and q is:
p * q = 20
To find q when p is 2, we can plug in p = 2 and solve for q:
2 * q = 20
q = 20 / 2
q = 10
Therefore, when p is 2, q is 10.
