The numeric constant of variation is 100
Step-by-step explanation:
Direct proportion means that increase in one variable cause increase in other variable
Here,
It is given that
y varies directly as x
y∝x
when the proportionality symbol is removed a proportionality constant is introduced
[tex]y = kx[/tex]
Given that
y = 100 when x = 4
Putting the values
[tex]400 = k * 4\\k = \frac{400}{4}\\k = 100[/tex]
The numeric constant of variation is 100
