The equation can be used to find other combinations of b and c will be b = 50√c. Then the correct option is B.
What are ratio and proportion?
A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.
The variable b varies directly as the square root of c.
b ∝ √c
If the proportionality sign is removed with the equal sign, then a constant (k) is introduced.
b = k√c
If b = 100 when c = 4.
Then the value of k will be
100 = k√4
100 = 2k
100 / 2 = k
k = 50
Substitute the value of k in equation, then the equation will be
b = 50√c
The equation can be used to find other combinations of b and c will be b = 50√c.
Then the correct option is B.
