the diameter of a hydrogen atom is about 5×10^-15 meter. suppose 8.4×10^8 hydrogen atoms were arranged side by side in a straight line. multiply these numbers to find the length of this line of atoms. what is the length in scientific notation?

select one:

a. 4.2×10^−2 meter
b. 0.042 meter
c. 42×10^−3 meter
d. 4.2×10^−3meter

I'm a few years late, lol, but um the answer is 42 x meters

For all the people who still need the answer.

Step-by-step explanation:

5 x and 8.4 x

5 x 8.4 = 42  (multiply like terms)

+ =  (add the exponents)

42 x

the data of the detroit pistons in numerical order from least to greatest is 0.30, 0.37, 0.55, 0.62, 0.69, 0.72, 0.73, 0.75, 0.77, 0.78, 0.80, 0.81, 0.81, 0.83, 0.84, 0.89

the data of the miami heat in numerical order from least to greatest is 0.50, 0.50, 0.56, 0.57, 0.67, 0.72, 0.72, 0.72, 0.75, 0.75, 0.76, 0.81, 0.82, 0.90, 1.00, 1.00

the detroit pistons median : 1.52

the miami heat median: 1.47

the iqr of this data is 0.05
