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>
 
        
                    
             
        
        
        
180 times 4/100= 7.20- Sales tax
180+7.20= $187.20 is the total cost

Hello there,
The <em>answer is </em>A' (-3,2).
<h3>Step-by-step explanation:-</h3>
From the image shown on the xy-plane, the coordinate of point A is at (3,-2).
The rule for rotation by 180° about the origin is (x,y)→(-x, -y), where (x,y) is the coordinate of image and (-x, -y) is the coordinate of the resulting pre-image.
Given the coordinate point A(3,-2), if this coordinate is rotated 180°, the resulting point A' will be located at (-3,-(-2)) = (-3,2).
Therefore, the answer will be <u>A'(-3,2)</u>

Answer:
   20/81
Step-by-step explanation:
Without parentheses, it is hard to tell what you are dividing. We assume you want ...
   (4/9)/(9/5)
Then ...

_____
As written (without parentheses), your expression is evaluated left to right, so evaluates to ...
   4/(9·9·5) = 4/405
 
        
             
        
        
        
Answer:
B. 
Step-by-step explanation:
Converting 60 hours to days:
24 hours = 1 day
60 hours = x day
Cross multiply

Divide both sides by 24 hours 

Thus,

The expression that shows how to convert 60 hours to days is:
