Question

Please help me with a-c

Answer 1

A) The negative rate indicates the glacier is getting smaller ( it is melting).

B) Multiply the size by the rate of change then subtract:

58850 x 0.0004 = 23.54 miles.

58,850 - 23.54 = 58,826.54 square miles.

C) A decade is 10 years.

Multiply the rate of change by 10: 0.0004 * 10 = 0.004

(1 - 0.004)^d or (0.996)^d, where d is the number of decades.
