Question

if √q is inversely proportional to r and √q=9 when r=4 what is the value of r when q=4​

Answer 1

Answer:

Let's take two quantities, x, and y. If x is directly proportional to the quantity y, we write it as x∝yx∝yor x=kyx=ky, where k is the constant of proportionality. If x is inversly proportional to the quantity y, we write it as x∝1yx∝1y or x=kyx=ky, where k is the constant of proportionality.
