Answer: Vertex (5 ,-9)
Step-by-step explanation:
Given : Function f(x) = (x – 8)(x – 2).
To find : What is the vertex of the quadratic function .
Solution : We have given that f(x) = (x – 8)(x – 2).
On removing parenthesis
f(x) = x²-2x -8x +16.
f(x) = x²-10x +16.
We need to find vertex of this function ,
Vertex: (h, k)
h = -.
Plugging values
h = -.
h = 5 this is the x- coordinate,
Now , we will plug x= 5 in quadratic function .
k = (5)²-10(5)+16.
k = 25-50 + 16
k= -9.
Vertex (5 ,-9)
Therefore, Vertex (5 ,-9).

Step-by-step explanation:
we know that
The<u><em> Triangle Inequality Theorem</em></u> states that the sum of any 2 sides of a triangle must be greater than the measure of the third side
Applying the triangle inequality theorem
Let
c ----> the measure of the length of the third side
1) 

2) 

so
The solution for the length of the third side is the interval (2,22)
All real numbers greater than 2 centimeters and less than 22 centimeters
Answer:
A
Step-by-step explanation:
With way one, we can easily count the tally marks, but with way 2 it becomes much harder for us to count the tallies when we are done.
