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>
You can use substitution here. First, get y alone:
14x + y = -4
subtract 14x from each side
y = -4 - 14x
Then, plug y into the second equation
-4 - 14x = 3x² - 11x - 4
then solve from there
