Human hair grows at a rate of about 6.849 x 104 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 of the range. Express your answer in scientific notation. Do not round your answer.
The difference between the high end and the low end of the range can be calculated by subtracting the low end from the high end of the range.
High end: 6.849 x 10^4 cm per hour
Low end: 2.329 x 10^-2 cm per hour
Difference = High end - Low end
= (6.849 x 10^4) - (2.329 x 10^-2)
To subtract these values, we need to express them with the same exponent.
6.849 x 10^4 = 68490 x 10^0 = 68490
2.329 x 10^-2 = 0.02329 x 10^0 = 0.02329
Now we can subtract:
Difference = 68490 - 0.02329
Expressing this in scientific notation:
Difference = 6.849 x 10^4 - 2.329 x 10^-2
= 6.849 x 10^4 - 2.329 x 10^4 x 10^-2
= (6.849 - 2.329 x 10^4) x 10^4
= 4.520 x 10^4
Therefore, the difference between the high end and the low end of the range is 4.520 x 10^4.
To find the difference between the high end and the low end of the range, we subtract the low end value from the high end value.
High end of the range = 6.849 x 10^4 cm per hour
Low end of the range = 2.329 x 10^-2 cm per hour
Difference = High end - Low end
Difference = (6.849 x 10^4) - (2.329 x 10^-2)
To subtract these values, we can put them in the same scientific notation format:
Difference = (6.849 x 10^4) - (0.02329 x 10^4)
Now, we can subtract the coefficients:
Difference = (6.849 - 0.02329) x 10^4
Difference = 6.82571 x 10^4
Therefore, the difference between the high end and the low end of the range is 6.82571 x 10^4 cm per hour.
To find the difference between the high end and the low end of the range, we subtract the low end from the high end.
High end of the range: 6.849 x 10^4 cm per hour
Low end of the range: 2.329 x 10^-2 cm per hour
Subtracting the low end from the high end:
(6.849 x 10^4) - (2.329 x 10^-2)
In scientific notation, we need to adjust the numbers so that they have the same exponent. We can do this by converting the low end to scientific notation with the same exponent as the high end:
(6.849 x 10^4) - (2.329 x 10^-2 x 10^4)
Simplifying:
(6.849 x 10^4) - (2.329 x 10^2)
Now, we can subtract:
6.849 x 10^4 - 2.329 x 10^2
The difference is:
6.849 x 10^4 - 2.329 x 10^2 = 6.846671 x 10^4
