Answer:
The distance traveled between 10 minutes and 15 minutes is increasing.
Step-by-step explanation:
Jacob is going on a road trip across the country. He covers 10 miles in 15 minutes.
Therefore, between the 10 minutes and 15 minutes, Jacob was in motion and if he covers 10 miles in 15 minutes with a constant speed, then Jacob will cover miles in that period.
So, the distance traveled between 10 minutes and 15 minutes is increasing.

Answer:
Option B. minimum is correct for the first blank
Option C. 6 is correct for second blank.
Step-by-step explanation:
In order to find the maxima or minima of a function, we have to take the first derivative and then put it equal to zero to find the critical values.
Given function is:
Taking first derivative
Now the first derivative has to be put equal to zero to find the critical value
The function has only one critical value which is 5.
Taking 2nd derivative
As the value of 2nd derivative is positive for the critical value 5, this means that the function has a minimum value at x = 5
The value can be found out by putting x=5 in the function
Hence,
<u>The function y = x 2 - 10x + 31 has a minimum value of 6</u>
Hence,
Option B. minimum is correct for the first blank
Option C. 6 is correct for second blank.
