<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)
This is for 2.X=22 so the total angle is 90° and you take away 68° and that leaves you with 22°
Answer:
10 hrs
Step-by-step explanation:
just divide 24 km by 8 hrs to get 3km per hour then
divide 30 by 3 to get 10 hrs
Tan(35)=x/12
x=12*tan(35)=8.40
Answer:
Step-by-step explanation:
Part A
Part B
- 5.50x = 62.50 - 35
- 5.50x = 27.50
- x = 27.50/5.50
- x = 5
