Answer:
v = 99
Step-by-step explanation:
Given v varies directly as g then the equation relating them is
v = kg ← k is the constant of variation
To find k use the condition v = 36 when g = 4 , then
36 = 4k ( divide both sides by 4 )
9 = k
v = 9g ← equation of variation
When g = 11 , then
v = 9 × 11 = 99
Is that just the question? I can help you out but it doesn’t make any sense.
