For the inverse variation equation p=8/V what is the value of Vwhen p=1/2?

NISA [10]

Answer:

v = 16

Step-by-step explanation:

p = 8/v and p = 1/2. Equating these two, we get 8/v = 1/2.

Inverting both sides, we get v/8 = 2.

Find the vaue of v by multiplying both sides by 8: v = 16

faltersainse [42]

$nPr = \frac{n!}{(n - r)!}$

$5P2 = \frac{5!}{(5 - 2)!} = \frac{5 \times 4 \times 3 \times 2 \times 1}{3 \times 2 \times 1} = 20$
