## anonymous one year ago is this an example of nonlinear or linear?

1. jim_thompson5910

linear = straight line

2. jim_thompson5910

each piece looks linear, but overall it's not linear since it's not a full straight line

3. jim_thompson5910

I'd have to see the full problem myself (eg: screenshot)

4. zzr0ck3r

also, if this is for higher order class, linear must also go through the origin. So y=mx+b is linear iff b=0

the distance in y centimeters of an ant from a hole in the tree for a certain amount of time x in seconds is shown in the graph:|dw:1443325550906:dw| is the graph linear or nonlinear?

6. DanJS

no curvature

7. DanJS

or accellerations

8. anonymous

?

9. DanJS

The ant moves at a constant velocity. F = m*a = m* dv/dt = m* 0 = 0 does not accelerate ,

10. DanJS

The ants velocity is the slope at any point on the position V. time graph The slope is constant, and is the Velocity,

11. anonymous

ok but what want to know is it linear or nonlinear?

12. DanJS

non-linear position vs time graphs will have a continuously changing slope , when the ant changes velocity

13. DanJS

ha forget all that if you want, they are lines

14. DanJS

The slopes of A , B, and C line segments, are all constant values

15. DanJS

The ant moves out to 12 at a uniform speed, stops and waits at rest for some time, then moves 12 in the other direction back at another uniform speed,

16. marcelie

when its a linear its usually the odd exponents curve its usually the even exponent
