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>
Answer:
Area = 22.3 m^2
Perimeter 27.4 m^2
Step-by-step explanation:
Perimeter = __ m
Area __ m^2
The area of the triangle is about 4.2,
The area of the square is 4,
The area of the semicircle is 14.1,
14.1 + 4.2 + 4 = 22.3
Area = 22.3 m^2
9.4 + 6 + 4 + 4 + 4 = 27.4
Perimeter = 27.4 m^2
Therefore the area of the shape is about 22.3 m^2 and the perimeter is about 27.4 m^2.
The multiply choice were worth 4 points.
Gretchen= 18x+19
Ezia= 15x+31
So basically you can enter any number. At first I picked 3 and then I did the math and I got 73 points for Gretchen and 76 points for Ezia.
Then I pick four and then I got 91 points for them both. This is how I got the answer:
18x+19=15x+31
18(4)+19=15(4)+31
72+19=60+31
91=91
I think the remaining number is x
28 units cubed I believe to be the right answer
