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)
The expert examines linear algebra for drying time.
