question 20 of 24
perform an experiment in which you roll a ball 43,700 cm before it comes to a stop. write this measurement in scientific notation.
a. 4.37 x 10^(-4) cm
b. 4.37 x 10^4 cm
c. 4.37 x 10^3 cm
d. 4.37 x 10^5 cm

Explanation:

Step1: Recall scientific - notation form

Scientific notation is $a\times10^{n}$, where $1\leqslant a<10$ and $n$ is an integer.

Step2: Convert 43700 to scientific notation

Move the decimal point 4 places to the left to get $a = 4.37$. Since we moved the decimal point 4 places to the left, $n = 4$. So, $43700=4.37\times10^{4}$.

Answer:

B. $4.37\times 10^{4}\text{ cm}$
