Question: Solve the given problems by determinants, set up appropriate systems of equations. All numbers are accurate to at least two significant digits. The increase L

Solve the given problems by determinants, set up appropriate systems of equations. All numbers are accurate to at least two significant digits.

The increase L in length of a long metal rod is a function of the temperature T (in °C) given by L = a + bT + cT² , where a, b, and c are constants. By evaluating a, b, and c, find L = f (T), if L = 6.4 mm for T = 2.0°C, L = 8.6 mm for T = 4.0°C, and V = 11.6 mm for T = 6.0°C.
