Answer:even,neither,odd,neither
Step-by-step explanation:I’m not explaining I just gave you the answers
1. [tex]f(x) = \sqrt{x^2 - 9}[/tex] is even.
2. g(x) = |x - 3| is neither even nor odd.
3. f(x) = 1/2 is neither even nor odd.
4. [tex]f(x) = x / (x^2 - 1)[/tex] is odd.
5. [tex]g(x) = x + x^2[/tex] is neither even nor odd.
To determine whether each function is even, odd, or neither, we need to apply the definitions of even and odd functions:
1. An even function satisfies f(x) = f(-x) for all x in its domain.
2. An odd function satisfies f(x) = -f(-x) for all x in its domain.
Let's analyze each function:
1. [tex]f(x) = \sqrt{x^2 - 9}[/tex]
To determine if this function is even or odd, we need to check f(x) and f(-x):
[tex]f(x) = \sqrt{x^2 - 9}\\f(-x) = \sqrt{(-x)^2 - 9} = \sqrt{x^2 - 9}[/tex]
Since f(x) = f(-x), the function is even.
2. g(x) = |x - 3|
To determine if this function is even or odd, we need to check g(x) and g(-x):
g(x) = |x - 3|
g(-x) = |-x - 3|
Since |-x - 3| is not equal to |x - 3|, the function is neither even nor odd.
3. f(x) = 1/2
Since this is a constant function (not dependent on x), it is neither even nor odd.
4. [tex]f(x) = x / (x^2 - 1)[/tex]
To determine if this function is even or odd, we need to check f(x) and f(-x):
[tex]f(x) = x / (x^2 - 1)\\f(-x) = (-x) / ((-x)^2 - 1) = -x / (x^2 - 1)[/tex]
Since f(x) = -f(-x), the function is odd.
5. [tex]g(x) = x + x^2[/tex]
To determine if this function is even or odd, we need to check g(x) and g(-x):
[tex]g(x) = x + x^2\\g(-x) = -x + (-x)^2 = -x + x^2[/tex]
Since g(x) is not equal to g(-x), the function is neither even nor odd.

PLEASEEE HELPPPP IF CORDINATES PF G ARE (3,8) WHAT ARE THE CORDINATES OF G’’
Answer: B, (4.5 , 12)
Step-by-step explanation:
This ellipse is centered at the origin. Find it’s equation. Verticles: (0,-6) (0,6) Foci: (0,-2) (0,2)
The equation of the ellipse will be x² / 36 – y² / 32 = 1.
What is an ellipse?An ellipse is a locus of a point that moves in a plane such that the sum of its distances from the two points called foci adds up to a constant. It is taken from the cone by cutting it at an angle.
This ellipse is centered at the origin.
Vertices: (0,-6) (0,6)
Foci: (0,-2) (0,2)
Then the equation of the ellipse will be given as
x² / a² – y² / b² = 1
Let c be the distance between the origin to foci.
Then we have
c = 2
And the value of a will be
a = 6
Then the value of a² will be
a² = 6² = 36
The value of b is the distance from center to one of the Co-vertices. Then the value of b² will be
a² – b² = c²
36 – b² = 2²
b² = 36 – 4
b² = 32
Then the equation of the ellipse will be x² / 36 – y² / 32 = 1.

7. f(x) = 2x + 5 What is the value of x if f(x) = 25 ?
Answer:
x=10
Step-by-step explanation:
set the 2 equations equal to each other
25=2x+5 -> subtract 5
20=2x -> divide by 2
10=x ->answer!
Hope that helps!
Answer:
x = 10
Step-by-step explanation:
f(x) equals both 25 and 2x + 5, so set the equations equal to one another and solve for x.
2x + 5 = 25
2x = 20
x = 10
Plug in what you got for x to check if it is right
2(10) + 5 = 25
20 + 5 = 25
25 = 25

The shape is made from a triangle and a

AD = 21 cm
Angle AOD = 140°
Angle OAD = 24°
Total marks: 5
9514 1404 393
Answer:
59.8 cm
Step-by-step explanation:
The length of arc ABC is ...
s = rθ
s = (9 cm)(220/180π) = 11π cm ≈ 34.558 cm
The length of segment CD is 9 cm less than the length of segment OD. OD can be found using the law of sines.
OD/sin(A) = AD/sin(O)
OD = AD·sin(A)/sin(O) = (21 cm)sin(24°)/sin(140°) ≈ 13.288 cm
Then the length of CD is ...
CD = OD -9 cm = (13.288 cm) -(9 cm) = 4.288 cm
The perimeter is the sum of the segment and arc lengths:
P = ABC + CD +AD
P = 34.558 cm + 4.288 cm + 21 cm = 59.846 cm
The perimeter of the shape is about 59.8 cm.

Wo groups are hiking at about the same speed. Mario's group hikes for 2.5 hours. Seema's group hikes for 4.7 hours and covers 8.8 more miles. How fast are the hikers going? Solve the equation below to find out. 4.7x = 2.5x + 8.8
Answer:
x = 4 miles per hour
Step-by-step explanation:
4.7x = 2.5x + 8.8
Collecting like terms
4.7x - 2.5x = 8.8
2.2x = 8.8
x = 8.8 / 2.2
x = 4 miles per hour

You spin the spinner and flip a coin. Find the probability of the compound event.
The probability of spinning a prime number and not flipping heads is...
Answer:
3/10 or 0.3
Step-by-step explanation:
The numbers in the spinners are given to be:
{1,2,3,4,5}
Total number of outcomes are: 5
On spinning the spinner, the outcomes which are prime are:
{2,3,5}
Hence, the probability that a prime number is obtained is:
3/5
Also, the probability that a head is not obtained i.e. a tail is obtained is:
1/2
Hence, the compound probability of spinning a prime number and not flipping head is:
3/10 or 0.3
