Answer: 
Step-by-step explanation:
You need to used the following formula:
Where "V" is the speed, "d" is the distance and "t" is the time.
In this case you know that Kevin traveled at a constant speed on the highway from Hickory Hills to Chicago in 20 minutes (which is 
) and the distance is 17 miles. Then, you can identify that:
Therefore, knowing these values, you can substitute them into the formula. Then, you get:
Answer:
positive
Step-by-step explanation:
The discriminant is positive
If there are 2 real roots ( where it crosses the x axis), then the discriminant is positive
215. If you divide 100,000 by 467 you get 214.132. Since you can’t have .132 of a person you need to round up to 215
Answer:
1,404,928 is the volume of a cube with a side length that measures 112 ft
By definition we have that the average rate of change of the function is given by:
Substituting values we have:
Rewriting we have:
Answer:
If x represents time, the average rate of change of the function f(x) in the first two seconds is 25.
