Human hair grows at a rate of about 6.849x10^-4 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.
To find the difference between the high end and low end of the range, we need to know the range itself. Unfortunately, the given information only provides the growth rate of human hair (6.849x10^-4 cm per hour), but it does not specify the range.
Without the range, we cannot calculate the difference between the high end and low end.
Please provide the range data, and we will be able to continue with the calculation.
To find the difference between the high end and the low end of the range, we need to determine the maximum and minimum growth rates.
Since no specific values are given for gender, genetics, age, and health, we can assume that the maximum and minimum growth rates are a result of the combined effects of all these factors.
Let's represent the maximum growth rate as R_max and the minimum growth rate as R_min.
Given:
Rate of hair growth = 6.849 × 10^-4 cm per hour
To find R_max, we need to consider the maximum possible value for the rate of hair growth. Since the given growth rate is already very small, it is unlikely that it can get much smaller. Thus, we assume R_min = 0.
Therefore, R_max = 6.849 × 10^-4 cm per hour.
The difference between the high end and the low end of the range can be calculated as follows:
Difference = R_max - R_min
= 6.849 × 10^-4 cm per hour - 0
= 6.849 × 10^-4 cm per hour
So, the difference between the high end and the low end of the range is 6.849 × 10^-4 cm per hour.
To find the difference between the high end and low end of the range, we need to determine the range of hair growth rates. Unfortunately, the given information does not provide the range directly. However, we can assume that the rate mentioned is either the high end or the low end of the range, and we can use that assumption to find the difference.
Given that the hair growth rate is approximately 6.849x10^-4 cm per hour, we can assume this as the high-end value. To find the low-end value, we need to consider the possible range of the hair growth rate.
Since the information states that hair growth rate depends on factors like gender, genetics, age, and health, we can assume that the low-end value would be significantly lower than the given rate. Considering this, a reasonable assumption for the low-end value would be approximately 0 cm per hour.
Therefore, the difference between the high and low ends of the range would be:
Difference = High-end rate - Low-end rate
Difference = (6.849x10^-4 cm/hr) - (0 cm/hr)
Difference = 6.849x10^-4 cm/hr
So, the difference between the high end and the low end of the range is 6.849x10^-4 cm/hr, expressed in scientific notation.
