If the function 1 in graph is a horizontal line y=3 then it has zero rate of change because y is same along the x axis.
Function 2 has rate of change of 2.
Y=mx+c m represents rate of change

Step-by-step explanation:
∠1 = ∠4 = 57° (vertical angles)
∠6 = 123° (same side interior angles are supplementary)
The circumference of a circle with an area of 50.3 m² is 25.12 m.
<h2>Further Explanation </h2><h3>Area </h3>
- Area is a measure of how much space is occupied by a given shape.
- Area of a substance is determined by the type of shape in question.
For example;
- Area of a rectangle is given by; Length multiplied by width
- Area of a triangle = 1/2 x base x height
- Area of a circle = πr². where r is the radius of a circle,
- Area of a square = S², Where s is the side of the square.etc.
<h3>Perimeter </h3>
- Perimeter is defined as the distance along a two dimension shape. Perimeter of different shapes is given by different formulas
For example;
- The perimeter of a rectangle = 2(length+width)
- The perimeter of a triangle = a+b+c; where a, b and c are the sides of the triangle. etc.
- The Circumference of a circle = 2πr , where r is the radius of the circle
In this case;
The Area of a circle = 50.3 m²
π = 3.14
But; Area of a circle = πr²
Therefore;
3.14r²= 50.3 m²
r² = 50.3/3.14
=16.019
r = √16.019
= 4.0023
≈ 4.00
But;
Circumference of a circle is given by 2πr
Thus;
Circumference = 2 × 3.14 × 4.00
= 25.12 m
