Monday: 43.9 miles per hour. 5 hours.
Tuesday: 47.5 miles per hour. 3 hours.
We need to multiply each unit rate by the number of hours traveled per day.
Monday: 43.9 mph * 5 hours = 219.50 miles
Tuesday: 47.5mph * 3 hours = 142.50 miles
Total number of miles: 219.50 miles + 142.50 miles = 362 miles.
One 10 80 in 10 Is your answer for that question
Answer:
n=-1
Step-by-step explanation:
-8n+4(1+5n)=-6n-14
-8n+4+20n=-6n-14
12n+4=-6n-14
12n+6n=-14-4
18n=-18
I guess you could count by hand, but it would take a while.
C and D
<h3>Answers:</h3>
- (a) The function is increasing on the interval (0, infinity)
- (b) The function is decreasing on the interval (-infinity, 0)
=======================================================
Explanation:
You should find that the derivative is entirely negative whenever x < 0. This suggests that the function f(x) is decreasing on this interval. So that takes care of part (b).
The interval x < 0 is the same as -infinity < x < 0 which then translates to the interval notation (-infinity, 0)
Similarly, you should find that the derivative is positive when x > 0. So the function is increasing on the interval (0, infinity)
