Question

A certain mountain has an elevation of 19,257 feet. In 1918 the glacier of the peak covered 8 acres. By 2001 the glacier had melted to only one 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 average A of this glacier T years past 1918.

Answer 1

difference in acres, divided by the difference in years; gives an average yearly rate

Answer 2

so it would be 8-1=7
7 divided by 2001-1918=7/83
am I correct

Answer 3

1 - 8
----------- = -7/83
2001 - 1918

its decreasing at a rate of 7/83 per year, yes

Answer 4

thanks
