Answer:
Step-by-step explanation:
Considering a person peak blood is 0.07
It decrease by 4% every hour
a) Using exponential function

where,
a = 1 + r
r = -0.40%
Here,
C = 0.07,
a = 1 - 0.04 = 0.06

<h3>Therefore, hourly decay factor is 0.6</h3>
b)
Here the hourly decay factor is 0.6

c) Evaluate

0.0252g or 100mL
<h3>Thus, after 2 hours the blood is 0.0252g or 100mL</h3>
The answer is D cuz it cross the x
