Question

2 math questions? Algebra I?

Answer 1

A newly made car will have a model number, a parts number, and a serial number. A model number is assigned by the manufacturer to identify each type of car. A parts number identifies one part of the smaller parts that make up the car. A serial number is unique to each car produced and identifies it.

Which relation is a function?

(parts number, serial number)

(model number, parts number)

(serial number, model number)

(serial number, part number)

Answer 2

Consider the two groups listed below. Which statement describes the sets?


the length of a swimming pool
the liquid volume of the pool
The relation (length, volume) is a function, but the relation (volume, length) is not.

The relation (volume, length) is a function, but the relation (length, volume) is not.

Both the relation (length, volume) and the relation (volume, length) are functions.

Neither the relation (length, volume) nor the relation (volume, length) is a function.

Answer 3

Help? @Chineseboy15 @zimmah

Answer 4

i don't really understand the questions myself very well either, but for the second one i assume it is neither, because you would need to know more than just the length of a swimming pool to know the volume (you need to know the depth and the width as well).

Answer 5

But it's asking if it is a function

Answer 6

well, i assume they mean "can you write a function of volume in terms of length" and the answer to that question would be no, because you are missing information. But i'm not 100% sure i interpret the question correctly.

Answer 7

Oh, okay.

Answer 8

Thanks, it was the right answer.

Answer 9

The answer to the first one is C. And the answer to the last one is D.

Answer 10

The problem is that I do not know what are model number, parts number, and serial number of a newly made car. Can you explain them to me.
