man hair grows at a rate of about 6.849×10−4cm per hour to 2.329×10−2cm 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 high end of the range is 2.329×10−2 cm per hour and the low end is 6.849×10−4 cm per hour. To find the difference, we subtract the low end from the high end:
2.329×10−2 - 6.849×10−4
= 2.329×10−2 - 0.0006849
= 2.3223151×10−2
Therefore, the difference between the high end and the low end of the range is 2.3223151×10−2 cm per hour.
Find 0.078−(5.2×10−3)
. Express your answer in scientific notation. Do not round your answer.(1 point)
×10−2
To solve 0.078 - (5.2×10^-3), we subtract the second number from the first:
0.078 - (5.2×10^-3)
= 0.078 - 0.0052
= 0.0728
To express the answer in scientific notation, we move the decimal point two places to the left:
0.0728 = 7.28×10^-2
Therefore, the answer is 7.28×10^-2.
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: 2.329×10^(-2) cm/hour
Low end: 6.849×10^(-4) cm/hour
Subtracting the low end from the high end:
2.329×10^(-2) cm/hour - 6.849×10^(-4) cm/hour = 2.2611×10^(-2) cm/hour
Therefore, the difference between the high end and the low end of the range is 2.2611×10^(-2) cm/hour.
To find the difference between the high end and the low end of the hair growth rate range, we need to subtract the low end of the range from the high end.
Given:
Low end of the range = 6.849×10^(-4) cm per hour
High end of the range = 2.329×10^(-2) cm per hour
Subtracting the low end from the high end:
(2.329×10^(-2)) - (6.849×10^(-4))
To subtract numbers in scientific notation, we need to ensure that the exponents are the same. In this case, we need to convert the low end into scientific notation with an exponent of -2.
(2.329×10^(-2)) - (6.849×10^(-4)) = (2.329×10^(-2)) - (6.849×10^(-2) × 10^(-2))
Now, we can subtract the two values:
(2.329×10^(-2)) - (6.849×10^(-2) × 10^(-2)) = 2.329×10^(-2) - 6.849×10^(-2) × 10^(-2)
To subtract the values with the same exponent, we only need to subtract the coefficients:
2.329 - 6.849 = -4.52
Finally, we rewrite the result in scientific notation by adjusting the exponent:
-4.52 × 10^(-2)
Therefore, the difference between the high end and low end of the hair growth rate range is -4.52 × 10^(-2) cm per hour.
