Human hair grows at a rate of about 6.849×10^−4 cm per hour to 2.329×10^−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.(1 point)
To find the difference between the high end and low end of the range, we subtract the low end from the high end.
2.329×10^−2 cm per hour - 6.849×10^−4 cm per hour
This can be simplified by subtracting the exponents:
(2.329-6.849) ×10^−2 cm per hour
= -4.52×10^−2 cm per hour
Thus, the difference between the high end and low end of the range is -4.52×10^−2 cm per hour.
To find the difference between the high end and the low end of the range, we need to subtract the low end from the high end.
High end: 2.329 × 10^(-2) cm per hour
Low end: 6.849 × 10^(-4) cm per hour
Subtracting the low end from the high end:
2.329 × 10^(-2) - 6.849 × 10^(-4)
To subtract the numbers in scientific notation, we need to make sure that the exponents are the same. In this case, we need to convert the low end to match the exponent of the high end.
6.849 × 10^(-4) = 6.849 × 10^(-2 + 2) = 6.849 × 10^(-2)
Now, we can subtract the numbers:
2.329 × 10^(-2) - 6.849 × 10^(-2)
Since the exponents are the same, we can subtract the coefficients:
2.329 - 6.849 = -4.52
The difference between the high end and the low end is -4.52. To express this answer in scientific notation, we need to adjust the number and the exponent:
-4.52 = -4.52 × 10^0
Therefore, the difference between the high end and the low end is -4.52 × 10^0.
To find the difference between the high end and low end of the range, we subtract the low end from the high end.
High end: 2.329 × 10^(-2) cm per hour
Low end: 6.849 × 10^(-4) cm per hour
Taking the difference:
(2.329 × 10^(-2)) - (6.849 × 10^(-4))
= 2.329 × 10^(-2) - 6.849 × 10^(-4)
Since the exponents (powers of 10) are the same, we can subtract the coefficients directly:
= 2.329 - 0.6849
= 1.6441
Therefore, the difference between the high end and the low end of the range is 1.6441. In scientific notation, this is expressed as 1.6441 × 10^0.
