Question

Will gives best response + fan is someone can answer this!

When a baseball is hit, its height above the playing field is measured by a sensor. Determine an equation to describe the curve of best fit for the data collected by the sensor. This is for a parabola graph!



Time,x(s) Height, y (m)
0.5 14.5
1.0 24.2
1.5 31.4
2.0 35.7
2.5 38.4
3.0 38.2
3.5 35.9
4.0 31.3

Answer 1

is this linear algebra?

Answer 2

that is the only way I know how to do best fit parabolas.

Answer 3

Yes this is linear algebra, Parabolas

Answer 4

use the formula :
y = ax^2 + bx + c
take 3 points above like (1; 24.2),(2; 35.7), (3;38.2)
subtitute that points into equation above then solve for a,b, and c

Answer 5

@RadEn could you give me an example of one? Using the information i provided?

Answer 6

if this is linear algebra they do not want you to do that.

Answer 7

Im trying to find it in my book, its been a year or so....
