Y is inversely proportional to V1+x.<br> When x = 8, y = 2.<br> Find y when x = 15.
murzikaleks [220]

Answer:

y = 1.5

Step-by-step explanation:

Given x is inversely proportional to \sqrt{1+x} , then the equation relating them is

y = \frac{k}{\sqrt{1+x} } ← k is the constant of proportion

To find k use the condition when x = 8, y = 2

2 = \frac{k}{\sqrt{1+8} } = \frac{k}{\sqrt{9} } = \frac{k}{3} ( multiply both sides by 3 )

6 = k

y = \frac{6}{\sqrt{1+x} } ← equation of proportion

When x = 15 , then

y = \frac{6}{\sqrt{1+15} } = \frac{6}{\sqrt{16} } = \frac{6}{4} = \frac{3}{2} = 1.5
