Answer
No
Step-by-step explanation:
it is not a function because 9 and three are a pair but so are 27 and 3. that makes it not a function

Answer:
32.78
Step-by-step explanation:
Assuming that we have two right triangles joined together, with one having adjacent side a, with a side of 12 ft opposite reference angle 30°, and the other one having adjacent side b, with a side of 12 ft opposite reference angle 45°. Thus, a + b = length of AC.
Let's find a and b.
Finding a:
Reference angle = 30°
Opp = 12 ft
Adj = a
Using trigonometric ratio formula, we have:
tan(30) = 12/a
Multiply both sides by a
a*tan(30) = 12
Divide both sides by tan(30)
a = 12/tan(30)
a = 20.78 (nearest hundredth)
Finding b:
Reference angle = 45°
Opp = 12 ft
Adj = b
Using trigonometric ratio formula, we have:
tan(45) = 12/b
Multiply both sides by a
b*tan(45) = 12
Divide both sides by tan(45)
b = 12/tan(45)
a = 12
Length of AC = 20.78 + 12 = 32.78
Answer:
Let's solve for x.
2x−y=−5
Step 1: Add y to both sides.
2x−y+y=−5+y
2x=y−5
Step 2: Divide both sides by 2.
2x/2=y-5/2
Answer:
x=1/2y+-5/2

<em><u>Solution:</u></em>
Given that,

We have to find whether the above function is odd or even
If a function is: y = f(x)
If f(-x) = f(x), the function is even
If f(-x) = - f(x), the function is odd
Which is,

From given,

Replace x with -x

Therefore,

Thus the function g(x) is even
