Answer:
Exterior angles (in a regular polygon) add to 360°. So you would do 360/40 to get an answer of 9. That is not the fastest solution, but your (n−2)×180∘ is the sum of the interior angles. Since the polygon is regular, each interior angle is therefore n−2n×180∘
Step-by-step explanation:
(5,6) and (3,4)
x₁ y₁ x₂ y₂
y₂ - y₁ 4 - 6 -2
------------- = --------- = ------- = 1
x₂ - x₁ 3 - 5 -2
Equation: y = x
The relation that is a function is that represented in the fourth graph. y = 2IxI
You must know that for a relation to be a function, there can not be two different values of f (x) for the same value of x.
In other words, if we have two sets P and M.
A function "f" between them is a relation that assigns to each value of the set P a single value of the set M.
To quickly verify when observing a graph it draws vertical lines and if they cut the graph in two points then the relation is not a function because it assigns two different values of f (x) for the same value of x.
By doing this test you will verify that only the fourth image represents the graph of a function.
1 yard=36 inches
First find the number of centimeters is to multiply 36 (the number of inches per year) by 2.54 (the number of centimeters in an inch). Therefore there are 91.44cm in 1 yard.
