Answer 1

Answer:

1) A

2) A

3) C

4) D

Step-by-step explanation:

Exponential decay is for 1) because as the years pass, the depth decreases.

2) if it decreases by 2%, this means 100%-2%= 98%=0.98.

3) same as 2).

4) The equation for this situation can be represented with y=30(0.98)^x. when x is between 5 and 6, the depth of the lake is approximately 26.7 meters. So, it takes around 5 to 6 years for the depth of the lake to decrease to 26.7 meters.
