<u>Answer:</u>
0 ≤ x ≤ π
<u>Step-by-step explanation:</u>
In order to define the inverse cosine functions, the domains of the cosine functions are restricted.
One major condition to define an inverse of a function is that the original function must be one‐to‐one which means that one value from the domain should correspond to only one value in the range.
So we have a restriction that is placed on the values of the domain of the cosine function which is the following:
0 ≤ x ≤ π
Answer:
20 units
Step-by-step explanation:
Initial particle concentration = 80 units
Particles removed each hour = 50% of the remaining particles
To find:
Particle concentration after 2 hours = ?
Solution:
Particles removed in 1 hour = 50% of remaining particles
i.e. Particles removed in 1 hour = 50% of initial concentration
Particles removed in 1 hour = 50% of 80 = 40
Particles removed in next 1 hour = 50% of remaining particles
i.e. Particles removed in next 1 hour = 50% of concentration after 1 hour
Particles removed in next 1 hour = 50% of 40 = 20
Total particles concentration removed in 2 hours = 40 + 20 = 60 units
Therefore, particle concentration after 2 hours = Initial concentration - Total particle concentration removed in 2 hours
= 80 - 60 = <em>20 units</em>
Answer:
-44
Step-by-step explanation:
We have the expression

We need to find the value of the expression when x = -3 and y = 4
Then we must replace the variable with the number -3 and the variable y with the number 4
This is:



Remember that the absolute value always results in a positive number.
So

the answer is -44
