Answer:
Area of octagon = 100 - 2 = 98 cm²
Step-by-step explanation:
Area of octagon = area of square - area of 4 triangles that are formed in four corners
Area of square:
Side = Width of the octagon = 10 cm
Area = side * side
= 10 * 10
= 100 cm²
Area of triangle:
Base = 2cm
height = 2 cm
Area =
=
= 2 cm²
Area of octagon = 100 - 2 = 98 cm²

Range= {6, 0, 6, -1, 3)
It is a function
Step-by-step explanation:
It is a function because there is only one y value for each x value
Answer:
20 dollars back
Step-by-step explanation:
The answer is D, y - 4 = -2(x - 1).
Point Slope Form: y - y₁ = m(x - x₁)
Info Given:
Coordinates - (1,4)
Slope: -2
(1,4)
x₁ y₁
Plug slope and point into formula: y - 4 = -2(x -1)
Answer:
0.25
Step-by-step explanation:
simplify 4/16 to 1/4.
multiply 1/4 by 25/25.
then you get 25/100, which equals to 0.25
