Answer:
and 
Step-by-step explanation:
The correct equation is:

To solve by completing the square method.
Solution:
We have:

In order to solve by completing the square method we will carry out the following operations to the given equation to get a perfect square binomial.
We can write as:

[As
]
Adding both sides by 

Taking LCD to add fraction.


Taking square root both sides.


Subtracting both sides by
:


So, we have:
and 
and 
and
(Answer)
Answer: 35.9 degrees
Step-by-step explanation:
Since cosine(x) is adjacent/hypotenuse, cosine(x) = 47/58.
Therefore we can take the arc cosine of 47/58, and we get x is about 35.9

Step-by-step explanation:
Just took the k12 unit test, hope this helps!
The range of the function is {-34, -2, -20}
<h3>How to determine the range?</h3>
The function is given as:
f(x) = -2x^2 - 2
The domain is {-4, 0, 3}
Substitute the domain values in the function.
f(-4) = -2(-4)^2 - 2 = -34
f(0) = -2(0)^2 - 2 = -2
f(3) = -2(3)^2 - 2 = -20
This means that the range of the function is {-34, -2, -20}
