Answer:
-19 1/9
Step-by-step explanation:
Given:
The initial mass of an element is 800 grams.
Decay rate = 8.2% per day
Number of days = 15
To find:
The remaining element after 15 days.
Solution:
The exponential decay model is

Where, a is the initial value r is the rate of interest and t is time period.
Putting
in the above formula, we get




Therefore, the mass of the remaining element is 221.7 grams.
U have to solve it then right the equation down
(-1, -9) go 3 to the right and three down from the midpoint <3 pls mark brainliest
