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.

Answer:

P(t) = 282.2(1.009)^t

Step-by-step explanation:

Look at the attached image.

Hope you can read my handwriting. the image cut off the right side, b = 1.009213324... but question asks to round to nearest thousandth so it's 1.009

For the second part just use the equation to find P when t = -1 and see if P is less than (underpredicts) the number from the question or greater than (overpredicts) the number. I haven't calculated it but I think it will be smaller and thus underpredicts just from looking at the numbers when t = -1
