a) You put the scientific notation in expanded form, 671,000,000. From there just divide it by 60. 11,183,333.333 miles per minute.
b) Take the miles/minute rate and multiply it by 8.3; 92821666.6667 miles per 8.3 minutes.
Hope this helps :)

The true statement, regarding the signal of the graphed function, is given by:
F(x) > 0 over the interval (–∞, –4).
<h3>When a function is positive and when it is negative?</h3>
Looking at it's graph, we have that:
- The function is positive when it is above the x-axis.
- The function is negative when it is below the x-axis.
Researching this problem on the internet and looking at the graph of the function, the function is negative for <u>all values to the right of x = -4</u>, and positive to the left, hence the correct statement is given by:
F(x) > 0 over the interval (–∞, –4).
