Answer 1

Answer:

see explanation

Step-by-step explanation:

The statements tells us that w is inversely proportional to v and the equation relating them is

v = $\frac{k}{w}$ ← k is the constant of proportion

To find k use the condition v = 9, w = 5, that is

9 = $\frac{k}{5}$ ( multiply both sides by 5 )

45 = k

v = $\frac{45}{w}$ ← equation of proportion

When w = 4 , then

v = $\frac{45}{4}$ = 11.25
