Suppose , varies jointly with g and v, and j = 2 when g = 4 and v= 3. Find j when g = 8 and v= 11.

j = 44/3

Step-by-step explanation:

j varies jointly as g and v. This can be represented mathematically as:

.............(1)

Where k is a constant of proportionality

j = 2 when g = 4 and v = 3

Substitute these values into equation (1)

2 = k * 4 * 3

2 = 12 k

k = 1/6

when g = 8 and v = 11:

j = (1/6) * 8 * 11

j = 44/3

answer: c.  

step-by-step explanation:

mixtures containing substances that get attracted to magnet can be separated using a magnet. we can separate iron from a mixture of sand and iron, as only iron attracts to the magnet.
