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 of the range. Express your answer in scientific notation. Do not round your answer
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 = 2.329 x 10^-2 cm per hour
Low end of the range = 6.849 x 10^-4 cm per hour
To subtract these numbers, we subtract the coefficients and keep the same exponent:
(2.329 - 6.849) x 10^-2 cm per hour
Subtracting the coefficients gives: -4.520 x 10^-2 cm per hour
Therefore, the difference between the high end and the low end of the range is -4.520 x 10^-2 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: 2.329 x 10^-2 cm per hour
Low end: 6.849 x 10^-4 cm per hour
Difference = (2.329 x 10^-2) - (6.849 x 10^-4)
Difference = 2.329 x 10^-2 - 6.849 x 10^-4
To subtract numbers in scientific notation, we must have the same power of 10. In this case, we can convert the low end into scientific notation by multiplying it by 100:
Difference = 2.329 x 10^-2 - (6.849 x 10^-4 x 100)
Difference = 2.329 x 10^-2 - 6.849 x 10^-2
Now we can subtract the numbers:
Difference = 2.329 x 10^-2 - 6.849 x 10^-2
Difference = (2.329 - 6.849) x 10^-2
Difference = -4.52 x 10^-2
The difference between the high end and the low end of the range is -4.52 x 10^-2 cm per hour.
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 of the range = 2.329 x 10^-2 cm per hour
Low end of the range = 6.849 x 10^-4 cm per hour
Difference = High end - Low end
= (2.329 x 10^-2) - (6.849 x 10^-4)
= 2.329 x 10^-2 - 6.849 x 10^-4
To subtract the numbers in scientific notation, the exponents must be the same. Here, we can rewrite 6.849 x 10^-4 as 6.849 x 10^-2.
Difference = 2.329 x 10^-2 - 6.849 x 10^-2
= (2.329 - 6.849) x 10^-2
= -4.52 x 10^-2
Therefore, the difference between the high end and low end of the range is -4.52 x 10^-2 cm per hour.
