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.
Point-Slope:
y+16=-1/26*(x-19)
Finding the regular slope:
m=1/-26=0.03846
$281 = 5%
The total amount would be $5,620
Answer:
The correct answer for this problem is the 2nd one because all you have to do is count how far each one is from -1 and -2
Step-by-step explanation:
area = length times width, so length = area / width
5 1/5 mi^2 5.2 mi^2
Here, length = ------------------- = --------------- = 2.66666... mi = 2 2/3 mi (answer)
1 19/20 mi 1.95 mi
