Question

human hair grows at a rate of about 6.849 times 10^-4 cm per hour to 2.329 times 10^-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 is scientific notation. do not round your answer

Answer 1

The low end of the range is 6.849 × 10^-4 cm per hour and the high end of the range is 2.329 × 10^-2 cm per hour.

To find the difference between the high end and the low end, we subtract the low end from the high end:

(2.329 × 10^-2) - (6.849 × 10^-4) = 2.329 × 10^-2 - 6.849 × 10^-4

In scientific notation, the difference between the high end and the low end of the range is 2.329 × 10^-2 - 6.849 × 10^-4.
