R represents radius or the distance between two points, the pythagorean expression will be
r² = Δx² + Δy²
Δ means the change, Δx means the change of x, Δy means the change of y
Given:
(x₁,y₁) = (-5,-1)
(x₂,y₂) = (0,2)
Input the numbers to the expression
r² = Δx² + Δy²
r² = (x₂ - x₁)² + (y₂ - y₁)²
r² = (0 + 5)² + (2 + 1)²
r² = 5² + 3²
r² = 25 + 9
r² = 34
r = √34
The distance is √34 unit length
The answer is 4/16 put the 4 where it’s green and the 16 where it’s red
Huh? What are you saying?
Answer: 78125 ways
Step-by-step explanation:
Given : The number of possible grades = 5
The number of students in the class = 7
Then, the number of ways to assign grades to a class of seven students :_

Hence, there are 78125 ways to assign grades to a class of seven students .
A counter example disproves a statement.
The counter example for : the city of Portland is in Oregon would be : the city of Portland is in Maine.
The city named Portland can be found in both states.
