The quantity y is partly constant and partly varies inversely as the square of x. With P and Q as constants, a possible relationship between x and y is
A
y = Q + \(\frac{P}{x^2}\)
B
y = Q + px
C
y = \(\frac{PQ}{x^2}\)
D
y = Q - \(\frac{P}{x^2}\)
Verified Correct Answer: A.
Step-by-Step Mathematical Solution
Given the above statement,
\(y = Q + \frac{P}{x^{2}}\)
