The weight of a piece of wire is directly proportional to its length. a piece of wire is 25 cm long and has a weight of 6 grams. another piece of the same wire is 30 cm long. calculate the weight of the 30 cm piece of wire p is inversely proportional to m. p = 48 when m = 9. calculate the value of p when m = 12

Let w be the weight of the wire and l be the length of the wire.

Now, we have been given that  weight of a piece of wire is directly proportional to its length. Thus, we have

, where k is constant.

Now, given that a piece of wire is 25 cm long and has a weight of 6 grams.

l= 25, w=6

Now, the length of the wire is 30 cm. Hence, we have

Second question:

Given that p is inversely proportional to m.

Now, p = 48 when m = 9

Now, we calculate the value of p when m = 12

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.

answer: your correct answer is b. d.
