Answer:
The value 4.5 is rational and the value 15−−√ is irrational. The sum of 4.5 and 15−−√ has a non-repeating and non-terminating decimal expansion. Therefore, the sum of 4.5 and 15−−√ is irrational. I can't explan but that's the correct Answer
Note:xy means x times y and x(y) means the same thing
so
first we get rid of square root then
make the equation equal to zero becaues if
xy=0 then x or/and y=0
squareroot(y-1)+3=y
isolate the squareroot
subtrac 3 from boht sides
squareroot(y-1)=y-3
square both sides (since they are equal, you should be able to square both sides and still make it true)
(squareroot(y-1))^2=(y-3)^2
(y-1)=(y-3)(y-3)
y-1=y^2-6y+9
subtrac y from both sides
-1=y^2-7y+9
add 1 to both sides
0=y^2-7y+10
find what two number multiply to make 10 and add to get -7
the answer is -2 and -5
0=(y-5)(y-2)
therfore
y-5=0
and/or
y-2=0
therefor
y=5 or/and 2 might work
let's try out 2
square root(2-1)+3=2
square root(1)+3=2
1+3=2
false
so 2 doesn't work
let's try 5
squareroot(5-1)+3=5
squareroot(4)+3=5
2+3=5
5=5
true
y=5
Answer : YES!
Explanation : An OSHA inspection when was being conducted at Raul's workplace; He has full right to know about the results and can also ask/question his employer about the actions that they will be taking to fix if any issues are identified during the inspection.
As per the guidelines of OSHA which stands for The Occupational Safety and Health Act, employers are responsible for providing a safe and healthful workplace for their workers, also it gives full right to the employees to know what are the safety measures taken by their organization. OSHA is a federal law that was established in 1970 to ensure that America's workforce has a safe environment in which to work. The Occupational Safety and Health Administration (OSHA), the federal agency that enforces the OSH law was established by the law and was formed in 1971.

<h3>1. Are exponential function one to one. How can you tell?</h3>
- A function
is one-to-one if each value of 
corresponds to exactly one value of 
.
To demonstrate this, we take the Horizontal Line Test that states:
<em>A function has an inverse function if and only if there is no any horizontal line that intersects the graph of at more than one point.</em>
As you can see in the first figure, the horizontal line 
(the green one) intersects the graph of the exponential function 
(the red one) in just one point. If you take every horizontal line 
with 
any real number, you will find that every line intersects the exponential function in just one point. Therefore, this function is one-to-one
<h3>2. What does this tell you about their inverses?</h3>
Another important thing is that:
- A function has an inverse function if and only if is one-to-one.
As we have demonstrated that exponential functions are one-to-one by Horizontal Line Test, then we conclude exponential functions have inverse functions. The domain of the inverse function is the range of the original one and the range of the inverse function is the domain of the original one. The inverse of is 
whose graph is the second figure below.
