Question

The height of a ball when it is thrown into the air is shown by equation h = −16t2 + 20t + 3, where h is the height of the ball and t is time in seconds since the ball was released.
A or B?
A.
linear model
B.
nonlinear model

Answer 1

Hello,

a quadratic equation is not a linear model.

Answer 2

From

h = -16t² + 20t + 3

This is a quadratic equation, it is degree 2 equation.

A degree 1 equation is a linear equation or model.

Any degree greater than 1, as 2 is a non linear.

So  h = -16t² + 20t + 3, is a non linear model.

It is B.

I hope this helped.
