Answer:
3.5 mph
Step-by-step explanation:
Average rate of speed

There isn't a factor that isn't prime or composite.
Part A:
I have attached the graph of this system of inequalities.
Part B:
Plug in (8,10) into both equations
10 > 3(8) + 10
10 > 24 + 10
10 > 34
This is false!
10 < (-3/4)(8) - 1
10 < (-3)(2) - 1
10 < -6 - 1
10 < -7
This is also false!
So,
(8,10) is not included in the solution area for the system.
-6 is the rate of change.
Cos(x) is infinitely differentiable, can be expanded using Taylor's series.
The series about c can be expressed as

Substituting cos(x), c= π /4,we have

and since




we can simplify the expansion to

Note that the sign pattern is - - + + - - + + - - ..... following the sign pattern of the derivatives of cos(x).
