To approximate the value of √19 on a number line, we can start by finding the nearest whole numbers to 19, which are 4 and 5. We can then estimate the distance between these two whole numbers and divide it into equal parts.
Since 19 is closer to 5 than to 4, we can estimate that the value of √19 is closer to 4.5.
Therefore, the approximate value of 19−−√ is 4.5.
The correct response is:
4.5

To find the approximate value of 19-√, you can start by identifying the square root of 19 on a number line.
First, let's find the perfect square closest to 19, which is 16 (√16 = 4).
Now, we know that the square root of 19 is somewhere between √16 and √25 (which is 5).
Since √19 is closer to √16, we know that the value of 19-√19 will be closer to 4 than to 5.
The provided options are:
- 4.25
- 4.5
- 4.38
- 4.13
From the available options, the closest value to our estimate is 4.25. Therefore, the approximate value of 19-√ is 4.25.
