human hair grows at a rate of about 6.849 x 10^-4 cm per hour to 2.329 x 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 range. Express your answer in scientific notation. Do not round your answer.
The difference between the high end and the low end range of a human hair growth rate is 2.329 x 10^-2 cm per hour - 6.849 x 10^-4 cm per hour = 2.26051 x 10^-2 cm per hour.
To find the difference between the high end and low end range, we subtract the low end range from the high end range.
High end range = 2.329 x 10^-2 cm/hour
Low end range = 6.849 x 10^-4 cm/hour
Difference = High end range - Low end range
Difference = 2.329 x 10^-2 cm/hour - 6.849 x 10^-4 cm/hour
To subtract the values, we need to express them with the same exponents.
2.329 x 10^-2 cm/hour can be written as 2.329 x 10^-4 x 10^2 cm/hour
6.849 x 10^-4 cm/hour remains the same
Difference = (2.329 x 10^-4 x 10^2 cm/hour) - 6.849 x 10^-4 cm/hour
Difference = 2.329 x 10^-4 x 10^2 cm/hour - 6.849 x 10^-4 cm/hour
Now we can calculate the difference:
Difference = (2.329 x 10^-4 x 10^2 - 6.849 x 10^-4) cm/hour
Since both terms have the same exponent, we can combine them:
Difference = (2.329 x 10^-4 - 6.849 x 10^-4) cm/hour
Subtracting the values:
Difference = -4.52 x 10^-4 cm/hour
Therefore, the difference between the high end and low end range is -4.52 x 10^-4 cm/hour.
To find the difference between the high end and low end range of human hair growth rates, we can subtract the low end rate from the high end rate.
High end rate: 2.329 x 10^-2 cm per hour
Low end rate: 6.849 x 10^-4 cm per hour
Subtracting the low end rate from the high end rate, we get:
(2.329 x 10^-2) - (6.849 x 10^-4)
To subtract these numbers, we need to ensure that the exponent of the scientific notation is the same. In this case, both numbers have the same exponent, which is -2.
Next, we can subtract the coefficients:
2.329 - 6.849 = -4.52
Finally, we express the result in scientific notation:
-4.52 x 10^-2
Therefore, the difference between the high end and low end range of human hair growth rates is approximately -4.52 x 10^-2 cm per hour.
