The distance around a triangle, better noun as de "perimeter of a triangle"
is the total distance around the outside, which can be found by adding together the length of each side.
Perimeter (P) = Length A + Length B + Lenght C
In this case, we know that each side measure 2 \frac{1}{8}81 feet, 3 \frac{1}{2}21 feet, and 2 \frac{1}{2}21feet but we have to rewrite each one of this mixed fractions as improper fractions:
2 \frac{1}{8}81 = \frac{16 + 1}{8}816+1 = \frac{17}{8}817
3 \frac{1}{2}21 = \frac{6 + 1}{2}26+1 = \frac{7}{2}27
2 \frac{1}{2}21 = \frac{4 + 1}{2}24+1 = \frac{5}{2}25
Then we just add all of them to find the perimeter:
 = \frac{17 + 28 + 20}{8}817+28+20 = \frac{65}{8}865
A: The distance around a triangle is \frac{65}{8}865feet
If you are reffering to this dot plot, it would be 13 trees being studied.
Answer:
13 1/3 and 6 2/3.
Step-by-step explanation:
Let the 2 parts be x and (20 - x).
So x^2(20 - x) must be a maximum.
y = x^2(20 - x)
y = 20x^2 - x^3
Finding the derivative):
y' = 40x - 3x^2 = 0 for maxm/minm value.
x( 40 - 3x) = 0
40 - 3x = 0
3x = 40
x = 40/3.
This is a maximum because the second derivative y" = 40 - 6x = 40 - 6(40/3)) is negative.
So the 2 numbers are 13 1/3 and 6 2/3.
If the traslation is T(x,y)=(x-1,y+1) then:
Therefore A'=( -7,3).
