Hello from MrBillDoesMath!
Answer:
Increasing on the interval [-5, -2]
Discussion:
The function value remains unchanged on [-2, 1] and decreases on [1,8]
Thank you,

1 km = 1,000 m....so 322km = 322,000 m
so the falcon can fly 322,000 m per hr
A polygon has the following coordinates: A(3,1), B(5,3), C(2,5), D(-1,5), E(-4,3), F(-2,1). Find the length of DC.

To find the length of a line given two points, we are going to use the distance formula, which is defined below:

(
and
are the two points)
The points in this problem are (2, 5) and (-1, 5). We can find the distance of DC by substituting these values into the distance formula and simplifying, as shown below:

- Substitute values into formula

- Combine like terms and then simplify
to 0

- Compute


- Compute

The length of DC is 3.
I think you are right, it is (1,1).
