human hair grows at a rate of about 6.849 times 10^-4 cm per hour to 2.329 times 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 is scientific notation. do not round your answer
The low end of the range is 6.849 × 10^-4 cm per hour and the high end of the range is 2.329 × 10^-2 cm per hour.
To find the difference between the high end and the low end, we subtract the low end from the high end:
(2.329 × 10^-2) - (6.849 × 10^-4) = 2.329 × 10^-2 - 6.849 × 10^-4
In scientific notation, the difference between the high end and the low end of the range is 2.329 × 10^-2 - 6.849 × 10^-4.
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 of the growth rate.
The low end of the range is 6.849 × 10^(-4) cm per hour.
The high end of the range is 2.329 × 10^(-2) cm per hour.
To subtract these two values, we subtract the low end from the high end:
(2.329 × 10^(-2)) - (6.849 × 10^(-4))
To subtract two numbers in scientific notation, their exponents need to be the same. In this case, we can convert 6.849 × 10^(-4) to scientific notation with the same exponent as 2.329 × 10^(-2). Since they both have negative exponents, we can rewrite 6.849 × 10^(-4) as 6.849 × 10^(-2) × 10^(-2).
Now we can perform the subtraction:
(2.329 × 10^(-2)) - (6.849 × 10^(-2) × 10^(-2))
To subtract, we subtract the coefficients and keep the same exponent:
2.329 - 6.849 = -4.52
Now we express the result in scientific notation. The exponent is still -2, and the coefficient is -4.52. Since the coefficient is negative, we adjust the sign to negative:
-4.52 × 10^(-2)
Therefore, the difference between the high end and the low end of the range is -4.52 × 10^(-2) cm per hour in scientific notation.
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 value: 2.329 × 10^-2 cm per hour
Low end value: 6.849 × 10^-4 cm per hour
Difference = High end value - Low end value
= (2.329 × 10^-2) - (6.849 × 10^-4)
Since we are subtracting numbers in scientific notation, we should have both numbers in the same power of 10. To do this, we can rewrite the low end value as:
Low end value = 6.849 × 10^-4 cm per hour
= 6.849 × 10^-4 * 10^0 cm per hour
= 6.849 × 10^-4 * 1 cm per hour
= 6.849 × 10^-4 cm per hour
Now we can calculate the difference:
Difference = (2.329 × 10^-2) - (6.849 × 10^-4)
= 2.329 × 10^-2 - 6.849 × 10^-4
To subtract these numbers, we keep the base (2.329) and subtract the exponent (-2) from the exponent (-4):
Difference = 2.329 × 10^(-2-(-4))
= 2.329 × 10^(-2+4)
= 2.329 × 10^2
The difference between the high and low end of the range is 2.329 × 10^2 cm per hour.
