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
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:
John ski down the mountain is 1285.37 feet.
Step-by-step explanation:
Given : John is skiing on a mountain with an altitude of 1200 feet. The angle of depression is 21.
To find : About how far does John ski down the mountain ?
Solution :
We draw a rough image of the question for easier understanding.
Refer the attached figure below.
According to question,
Let AB be the height of mountain i.e. AB=1200 feet
The angle of depression is 21 i.e.
We have to find how far does John ski down the mountain i.e. AC = ?
Using trigonometric,
Therefore, John ski down the mountain is 1285.37 feet.
