A creep test is done at room temperature on a material on a metal alloy wire comprising of 30% Tin, 25% lead and a solid core copper of 40%. The test measures the increase in strain (Pa) over time (hr) while a constant load is applied to the test specimen wire. Fit the following data using quadratic regression and determine the strain for the duration time t= 5.625 hrs. (note use the rounded off coefficient values in calculating the function).
