The population of the United States since the year 1960 can be approximated by f ( t ) = 0.009 t 2 + 2.10 t + 182 where f ( t ) is the population in millions and t represents the number of years since 1960. a. Find the average rate of change in U.S. population between 1960 and 1970. Round to 1 decimal place. b. Find the average rate of change in U.D. population between 1960 and 1970. Round to 1 decimal place. c. Based on the answers from parts (a) and (b), does it appear that the rate at which U.S. population increases is increasing or decreasing with time?

I want to learn this topic l dont know anything about it
Solve the linear system of equations attached using Gaussian elimination (not Gauss-Jordan) and back subsitution.
Remember that:
A matrix is in row echelon form if
Any row that consists only of zeros is at the bottom of the matrix.
The first non-zero entry in each other row is 1. This entry is called aleading 1.
The leading 1 of each row, after the first row, lies to the right of the leading 1 of the previous row.
