A certain mountain has an elevation of 19,273 feet. In 1921, the glacier on this peak covered 4 acres. By 2001 this glacier had melted to only1 acre.(a) Assume that this glacier melted at a constant rate each year. Find this yearly rate.(b) Use your answer from part (a) to write a linear equation that gives the acreage A of this glacier t years past 1921.The yearly rate of change isacres/year.(Type an integer or a decimal. Round to the nearest thousandth.)What is the equation that gives the acreage of the glacier t years after 1921?(Simplify your answer. Type your answer in slope-intercept form. Use integers or decimals for any numbers in the equation.)
