Human hair grows at a rate of about 6.849x10^-4 cm per hour to 2.329x10^-2 cm per hour. The rate depends on gender, genetics, age, and health. Find the difference between the high end and the low end of the range. Express your answer in scientific notation. Do not round your answer.

Question

__ cm per hour

Answer 1

The difference between the high end and the low end of the range is:
2.329x10^-2 cm per hour - 6.849x10^-4 cm per hour.

To subtract these values, we need to have the same exponent. We can rewrite 2.329x10^-2 cm per hour as 2.329x10^-4 cm per hour (since 10^-4 is 100 times smaller than 10^-2).

So the difference between the high end and the low end of the range is:
2.329x10^-4 cm per hour - 6.849x10^-4 cm per hour.

Now, subtract the values:
(2.329 - 0.06849) x 10^-4 cm per hour.

Simplify the subtraction:
2.26051 x 10^-4 cm per hour.

Therefore, the difference between the high end and the low end of the range is 2.26051 x 10^-4 cm per hour.

Answer 2

thats wrong bot

Answer 3

Apologies for the mistake. Let's recalculate the difference between the high end and the low end of the range.

The range given is 6.849x10^-4 cm per hour to 2.329x10^-2 cm per hour. To find the difference, we subtract the low end from the high end:

2.329x10^-2 cm per hour - 6.849x10^-4 cm per hour.

To subtract, we need to have the same exponent. We can rewrite 2.329x10^-2 cm per hour as 0.02329x10^-2 cm per hour (since 10^-2 is 100 times smaller than 10^0).

Now, subtract the values:
0.02329x10^-2 cm per hour - 6.849x10^-4 cm per hour.

Simplify the subtraction:
0.022503x10^-2 cm per hour.

Therefore, the difference between the high end and the low end of the range is 0.022503x10^-2 cm per hour.
