A geometry app shows lengths that add up to 27.4 units.
The Pythagorean theorem can be used to find the lengths of the segments. Each length is the square root of the sum of squares of the difference in x-coordinates and the difference in y-coordinates.
segment AB: length = √(3²+8²) = √73 ≈ 8.544
segment BC: length = √(7²+4²) = √65 ≈ 8.062
segment CA: length = √(10²+4²) = √116 ≈ 10.770
Then the total perimeter is the sum of these lengths:
... 8.544 +8.062 +10.770 = 27.376 ≈ 27.4 . . . . units
Answer:
k=3
Step-by-step explanation:
+ we note f(p)= 
+ Because of "p-1 is a factor of f(p)", that means f(p)= (p-1)* g(p)
Then we have f(1)= (1-1)*g(1)= 0* g(1)= 0
+ We replace p=1 in f(p) and we have:
f(1)=0
that means: 
then 1+1+1-k = 0, 3-k=0 or k=3
Hope that useful for you.
Answer:
Following are the responses to these questions:
Step-by-step explanation:
In point a:
Please find the graph file in the attachment.
In point b:
This information is interesting for us, because we inform us about an important disease outbreak in such days and how the pandemic impacts major global communities like London as well as how the pattern in the recorded cases is increasing and decreasing.
In point c:
The data are sorted: 551, 1683, 3194, 4053, 4079, 5842, 5868
Mean
Median proves middle value or class so if ascending data is arranged = 4th term = 4053
A mode is of max 
Range It is also the difference between max and min values which indicates the overall distribution range 
The standard deviation
