Answer:
1.6 * 10^{-8}
Step-by-step explanation:
Given the following data;
Time = 0.000000016 nanoseconds
To express in standard scientific notation;
Scientific notation is a standard way of expressing very large numbers in powers of 10.
0.000000016 nanoseconds = 1.6 * 10^{-8} nanoseconds.
Note: count the number of zeros (0s) before 1 and write it to the power of 10.
3) For Zach, if his heart beats 15 times in 10 seconds, his heart beats 1.5 times in 1 second. Multiply this by 25 to get the number of times his heart will beat in 25 seconds → 1.5 * 25 = 27.5 times per 25 seconds. 1.5 * 60 = 90 times per minute. 1.5 * 120 = 180 times per two minutes. Do the same for your heart beats. 14 beats per 10 seconds is 1.4 beats per second. 1.4 * 25 = 35 times per 25 seconds. 1.4 * 60 = 84 times a minute. 1.4 * 120 = 168 times per two minutes.
4) Zach's equation would be H = 1.5n and yours would be H = 1.4n
5) Your heat beats just a little bit slower than Zachs. Everyone is different and there are many different things that can affect heart rate. Maybe he walked a little more than you did or maybe he was stressing about something which made his heart beat a little faster.
I hope this helps you!
