Answer:
Step-by-step explanation:
If two variables are directly proportional, it means that an increase in the value of one variable would cause a corresponding increase in the other variable. Also, a decrease in the value of one variable would cause a corresponding decrease in the other variable.
Given that v varies directly with g, if we introduce a constant of proportionality, k, the expression becomes
v = kg
If v = 36 when g = 4, then
36 = 4k
k = 36/4 = 9
Therefore, the direct variation equation is
v = 9g
when g = 11, then
v = 9 × 11
v = 99
