Answer:
Step-by-step explanation:
You already highlighted the term coordinate ratio in purple.
I belive your actually right and the letter answer is H (im really not sure)
Answer:
A: true
B: true
C: false
D: true
E: true
Step-by-step explanation:
A: always true, m is the slope, and b is the y-intercept (starting value)
B: always true, m is always constant within the equation
C: false, initial value can be 0, e.g. in the equation y=5x, the initial value is 0
D: always true, being a line is part of the definition of linear
E: true, if the equation is in the form x = [a number], it is a vertical line where the x value is always the given number

πr2 is an example of a (D) model.
<h3>What exactly is a model?</h3>
- A mathematical model is a system description that makes use of mathematical concepts and language.
- The process of developing a mathematical model is known as mathematical modeling.
- Natural sciences (physics, biology, earth science, chemistry), engineering disciplines (computer science, electrical engineering), and non-physical structures such as the social sciences all use mathematical models (such as economics, psychology, sociology, and political science).
- The use of statistical equations to solve problems in business or military operations is a large part of the field of operations research.
- Mathematical models are used in music, linguistics, and philosophy (for example, intensively in analytic philosophy).
- A model is, for example, the πr2 method for calculating the area of a circle.
Therefore, πr2 is an example of a (D) model.
