Step-by-step explanation:
The food and drink( orginally carbon compunds) we take in are broken down into carbon compounds and most simplest being glucose (C6H12O6). When this glucose reacts with oxygen it forms carbon dioxide and water. So, this where CO2 comes from in the body. Energy is also released in the reaction which why we feel energetic after having food. This process is called cellular oxidation.

Answer:
Population standard deviation (σ) = 0.3 in
Step-by-step explanation:
Sample mean = 3.07 in
Sample standard deviation (s) = 0.21 in
Sample size (n) = 62 cups
Population standard deviation (σ) = ?
The point estimate for the population standard deviation is given by sample standard deviation divided by the square root of the sample size:
13pi/12 lies between pi and 2pi, which means sin(13pi/12) < 0
Recall the double angle identity,
sin^2(x) = (1 - cos(2x))/2
If we let x = 13pi/12, then
sin(13pi/12) = - sqrt[(1 - cos(13pi/6))/2]
where we took the negative square root because we expect a negative value.
Now, because cosine has a period of 2pi, we have
cos(13pi/6) = cos(2pi + pi/6) = cos(pi/6) = sqrt[3]/2
Then
sin(13pi/12) = - sqrt[(1 - sqrt[3]/2)/2]
sin(13pi/12) = - sqrt[2 - sqrt[3]]/2
Answer:
BC = 17.2.
Step-by-step explanation:
Since CAB = 90º, this is a right triangle.
The triangle format is given below:
C
A B
We have that AB = 8.6, and angle B measures 60º.
Length of BC:
BC is the hypotenyse.
Side AB is adjacent to angle B = 60º.
In a right triangle, angle 
, it's adjacent side with length s and the hypotenuse h are related by the cosine of the angle, that is:
In this question, we have an angle of 60º, with has cosine 0.5. We also have that side AB = s = 8.6, and the hypotenuse h is side BC. So
BC = 17.2.
