\(P = \frac{Q}{12R}\)
\(P = \frac{12Q}{R}\)
\(P = 12QR\)
\(P = \frac{12}{QR}\)
Correct answer is B
\(P \propto \frac{Q}{R}\)
\(P = K \frac{Q}{R}\)
When Q = 36, R = 16, P = 27
Then substitute into the equation
\(27 = K \frac{36}{16}\)
\(K = \frac{27 \times 16}{36}\)
\(K = 12\)
So the equation connecting P, Q and R is
\(P = \frac{12Q}{R}\)
y varies directly as w2. When y = 8, w = 2. Find y when w = 3
18
12
9
6
Correct answer is A
\(y \propto w^2\)
y = kw2
8 = k(2)2
8 = k(4)
k = 8/4
k = 2
Thus y = 2w2
When w = 3, y = 2(3)2
y = 2 x 9 = 18
