<u>Answer: </u>
An audio cable is 15.9 dm long. The length of the audio cable in metre is 159m
<u>Solution: </u>
Given that audio cable is 15.9 dm long. We have to convert 15.9 decimetre to meter.
To convert decimetre(m) to metre(cm) we use the given formula
We know,
1m =10 dm
Therefore to convert any number in decimetre (dm) to metre (m) we multiply the given number by 10.
Here we have to convert 15.9 dm to m. Therefore multiplying 15.9 with 10 we get,
Thus the length of the cable in metre is 159 m.
Answer:
Step-by-step explanation:
The given function is
The range refers to the values of y for which x is defined.
We solve for x to obtain;
This is a polynomial function in y.
x is defined for all values of y.
Therefore the range is all real numbers.
or
The first choice is correct.
