Answer:
1.083
Step-by-step explanation:
Exact form: 13/12
Decimal form: 1.083 (put a line above the 3)
Mixed number form: 1 1/12
After 24 hours, 35.4% of the initial dosage remains on the body.
<h3>What percentage of the last dosage remains?</h3>
The exponential decay is written as:

Where A is the initial value, in this case 2.8mg.
k is the constant of decay, given by the logarithm of 2 over the half life, in this case, is:

Replacing all that in the above formula, and evaluating in x = 24 hours we get:

The percentage of the initial dosage that remains is:

13 and 14 becuase 13 being the third largest and 14 being the second largest
3(3) - (-8)/4 = 9 + 2 = 11 so (3,-8) is solution
3(4) - 4/4 = 12 - 1 = 11 so (4,4) is solution
answer
C. both ordered airs are solutions
