Answer:
1.97 ounces
Step-by-step explanation:
-The exponential decay function is given by the formula:

Given that the half-life is 4 days, we can substitute in the formula to solve the rate of decay for a single half-life:

#Since, 1 week has 7 days, 3 weeks is a 21-day period, thus, t=21.
#We substitute and solve for the amount remaining after 21days of decay:

Hence, the amount remaining after 3 weeks of decays is approximately 1.97 ounces
If each of the branches has half the area of the aorta, its linear scale factor is the square root of 1/2, or (√2)/2.
The diameter of one of the branches is (da×√2)/2.
3x+15 , this expression correctly combines the like terms
Answer: 28.84
Step-by-step explanation:
7/100 = 0.07
