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:
15
Step-by-step explanation:
1/8 times 120= 15
Answer:
Perimeter = 10x + 8 units.
Area = 6x^2 + 13x - 5 units^2.
Step-by-step explanation:
The perimeter is 2*length + 2*breadth
= 2(2x + 5) + 2(3x - 1)
= 4x + 10 + 6x - 2
= 10x + 8 units.
The area = length * breadth
= (2x + 5)(3x - 1)
= 6x^2 - 2x + 15x - 5
= 6x^2 + 13x - 5 units^2.
$33,075 = 0.05S + S
$33,075 = 1.05S
$33,075/1.05 = 1.05S/1.05
S= $31,500
Check
$31,500 * 5% = $1575 + $31,500 =$33,075
we have

Convert to vertex form

we know that
the equation of a vertical parabola in vertex form is equal to

where
(h,k) is the vertex

Group terms that contain the same variable, and move the constant to the opposite side of the equation

Complete the square. Remember to balance the equation by adding the same constants to each side


Rewrite as perfect squares


the vertex is the point 
therefore
<u>the answer is </u>
The y-value of the vertex is
