Answer:

Decay, 10%

Explanation:

0.9 < 1

So it's a decay

(1 - 0.9)×100 = 10%

Answer:

decay, 10%

Explanation:

y=.4(.9)^x

The equation is of the form

y =a b^x

b tells us growth or decay

b>1 growth

b<1 decay

This is decay

To find the percent decay take 1-b

1-.9 = .1

Change this to percent

10%
