Step-by-step explanation:
Answer:
cos (30 deg) = sqrt (3) /2
Step-by-step explanation:
COS = Adjacent / Hypotenuse
CosZ = 24/30
We conclude that the quotient as written as a simplified fraction is:
(3/10)/3.8 = 3/38
<h3>
How to find the quotient?</h3>
Here we want to find the quotient between a fraction and a number in decimal form:
(3/10)/3.8
To do that, we can write the quotient as a fraction by multiplying and dividing by 10, we will get:
3.8 = 3.8*(10/10) = 38/10
Then we can rewrite our quotient as:
(3/10)/3.8 = (3/10)/(38/10) = (3/10)*(10/38) = 30/380 = 3/38
And we can't simplify that fraction anymore, as 3 is not a factor of 38.
We conclude that the quotient as written as a simplified fraction is:
(3/10)/3.8 = 3/38

The substance's half-life is 5.5 days if the 11-gram sample of a substance that’s used to treat thyroid disorders has a k- the value of 0.125
<h3>What is exponential decay?</h3>
During exponential decay, a quantity falls slowly at first before rapidly decreasing. The exponential decay formula is used to calculate population decline and can also be used to calculate half-life.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
We have an exponential function:
Plug N = N⁰/2
Solving for t:
t = 5.54 ≈ 5.5 days
Thus, the substance's half-life is 5.5 days if the 11-gram sample of a substance that’s used to treat thyroid disorders has a k- the value of 0.125
