# Linear Algebra - drying time

The drying time of varnish depends on the amount of certain chemical that s added.

a. Determine a best (least-squares) ft parabola of the form:

T(m) = x1 + x2m + x3m^2 to the data provided n the table below

b) Also, estimate the drying time of the varnish when 3.5 grams of the chemical are added.

Mass (m) of Additive (Grams) Drying Time (T) (Hours)

1 8.5

2 8.0

3 6.0

4 5.0

5 6.0

6 5.5

7 6.5

8 7.0
