Step-by-step explanation:
Find the range of the following piecewise function.
[0,11)
(-4,6]
(0,11]
[-4,6)
Given:
The piecewise function is
[tex]f(x)=\begin{cases}x+4 & \text{ if } -4\leq x<3 \\ 2x-1 & \text{ if } 3\leq x<6 \end{cases}[/tex]
To find:
The range of given piecewise function.
Solution:
Range is the set of output values.
Both functions [tex]f(x)=x+4[/tex] and [tex]f(x)=2x-1[/tex] as linear functions.
Starting value of [tex]f(x)=x+4[/tex] is at x=-4 and end value is at x=3.
Starting value: [tex]f(-4)=-4+4=0[/tex]
End value: [tex]f(3)=3+4=7[/tex]
Starting value of [tex]f(x)=2x-1[/tex] is at x=3 and end value is at x=6.
Starting value: [tex]f(3)=2(3)-1=5[/tex]
End value: [tex]f(6)=2(6)-1=11[/tex]
Least range value is 0 at x=-4 and 0 is included in the range because -4 is included in the domain.
Largest range value is 11 at x=6 and 11 is not included in the range because 6 is not included in the domain.
So, the range of the given piecewise function is [0,11).
Therefore, the correct option is A.

If the binomial (x−7) is a factor of the polynomial function f(x), which statement must be true?
If the binomial (x−7) is a factor of the polynomial function f(x), then the true statement is f(7) = 0
How to determine the true statement?The given parameters are
The binomial (x−7) is a factor of the polynomial function f(x)
The above means that
When the function f(x) is divided by x - 7, it has no remainder
So, we have
x - 7
Set to 0
x - 7 = 0
Add 7 to both sides
x = 7
Substitute x = 7 in f(x) = 0
f(7) = 0
Hence, if the binomial (x−7) is a factor of the polynomial function f(x), then the true statement is f(7) = 0

Determine whether the following statement is true or false. Explain.
The graph of y = |x-2|- 2 is a translation two units to the right and two units upward of the graph of y = |x|.
Choose the correct answer below.
A. True, because the graph of y = f(x - h) + k is the translation of the graph of y = f(X) |k| units upward if k= 0 or downward if k < 0, and h units to the right if h> 0 or to the
left if h < 0.
B. True, because the graph of y = f(x- h) + k is the translation of the graph of y = f(x) In| units upward if h = 0 or downward if h < 0, and k units to the right if k> O or to the
left if k < O
C. False, because the graph of y = f(x- h) + k is the translation of the graph of y = f(x) |k| units to the right if k>0 or to the left if k < 0, and h units upward if h downward if h < 0.

A seal went 25 feet below sea level to catch a fish. A sea lion dove 10 feet less than three times as deep as the seal to catch a larger fish. What is the sea lion's position in relation to sea level?
Answer:
65 feet below sea level.
Step-by-step explanation:
With the information provided, we can create the following equation for the position of the sea lion (p)
p = 3x - 10
In this equation, x would be the final position of the seal when it caught the fish. Since we are told that the seal's position is 25 feet below sea level then we can plug in this value as x and solve for p...
p = (3 * 25) - 10
p = 75 - 10
p = 65
Finally, we can see that the sea lion's position is 65 feet below sea level.

If a rotation takes triangle CAT to C′A′T′, what is C′T′?
triangle CAT with vertex A at negative 2 comma 1, vertex T at negative 1 comma 4 and vertex C at 0 comma 0, side AT has a measure of square root of 10 units, side TC has a measure of square root of 17 units, and side AC has a measure of square root of 5 units
3
square root of 17
5
Cannot be determined
The measure of C'T' is √17 units after the rotation .
Rotation of a graph is a transformation in which the figure is rotated around a fixed point.
The rotation can be clockwise or anti-clockwise.A complete rotation of 360 degrees puts the graph back into its original position.Rotation does not change the side length of the figure that is rotated.When a polygon is rotated about a fixed point then the transformed figure is congruent to the original figure.The given triangle is CAT and it has the coordinates as C(0,0) , A(-2,1) and T(-1,4).
So when the figure is rotated about a fixed point the side lengths will remain same as the original figure.
C'T' = CT = √17 (the value of CT is given)
Hence the length of C′T′ is √17 units .

What is the domain of the function f(x) = + 5?
f(x) ≥ –9
f(x) ≥ –5
f(x) ≥ 5
f(x) ≥ 9
Answer:
The domain of the function is:
[tex]\mathrm{Domain\:of\:}\:\sqrt{x+5}\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\ge \:-5\:\\ \:\mathrm{Interval\:Notation:}&\:[-5,\:\infty \:)\end{bmatrix}[/tex]
Step-by-step explanation:
Given the function
[tex]f\left(x\right)\:=\sqrt{x+5}[/tex]
We know that the domain of a function is the set of input or argument values for which the function is real and defined.
From the function, it is clear that for the values x<-5, the function becomes undefined.
For example, for x=-6
√x+5 = √-6+5 = √-1 which is undefined
and for x=-5
√x+5 = √5+5 = √0 which is defined
Thus, the domain of the function is:
[tex]\mathrm{Domain\:of\:}\:\sqrt{x+5}\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\ge \:-5\:\\ \:\mathrm{Interval\:Notation:}&\:[-5,\:\infty \:)\end{bmatrix}[/tex]

A contractor bought 8.2 ft^2 of sheet metal. He had used 4.9ft^2 so far and has $ 59.40 worth of sheet metal remaining. The equation 8.2x-4.9x=59.4 represents how much sheet metal is remaining and the cost of the remaining amount. How much does sheet metal cost per square foot?
Answer: Each square foot of metal costs $14.97
Step-by-step explanation:
He initially had 8.2 ft^2 of metal.
He used 4.9ft^2 of metal, then he now has:
8.2 ft^2 - 4.9 ft^2 = 3.3 ft^2
And this 3.3 ft^2 is whort $49.40
Then if X is the cost per square foot, we have the equation:
3.3ft^2*X = $49.40
We can solve it for X as:
X = ($49.40/3.3ft^2) = $14.97 ft^-2
This means that each square foot costs $14.97

I could have given up, but I thought about my grandmother. She always told me that "people who believe that science is the answer to everything are missing out on everything else." With her words in mind, I searched some more. There were many facts that hinted that dragons may not be fictional. I noticed that cultures across the world all described dragons in similar ways. This was odd because they had no way to communicate with each other. I found dragons mentioned in more than just stories. They appeared in old legal papers, in the travel logs of Marco Polo, and in the Bible. I saw that the Chinese calendar uses a different animal each year. Dragons are included along with eleven real animals. I began to believe it was a real possibility that all of these people were talking about a creature that actually existed.
The text discusses the Chinese calendar by writing, "Dragons are included along with eleven real animals."
What does that imply? (5 points)
Dragons are the only fake animal on the Chinese calendar.
Dragons are not the only fake animal on the Chinese calendar.
Dragons are real because all the other animals on the calendar are fake.
Dragons are real because all the other animals on the calendar are real.
Answer:
Dragons are real because all the other animals on the calendar for real.

Answer:

Step-by-step explanation:
triangles always = 180 degrees
we know there is a 90 degree angle so 180-90=90
we know the other angle is 20 degrees so you do 90-20 which equals 70
now we know that the angle with x equals 70
so then you do 70-16 which equals 54
now just divide 54 by 6 and you get 9
so x=9

Raymond's bank account was overdrawn by $32.55. He makes two deposits of $100 each and then makes a purchase of $86.72. What is his account balance?
Raymond's account balance after depositing two deposits of $100 , purchase of $86.72 with overdrawn amount $32.55 is equal to $80.73.
As given in the question,
Raymond's bank account has:
Overdrawn amount in bank = $32.55
Deposits amounts by Raymond's = 2 × ( $100 )
= $200
Purchase amount = $86.72
Account balance in Raymond's account = ( $200 - $32.55 - $86.72 )
= ( $200 - $119.27 )
= $80.73
Therefore, Raymond's account balance after depositing two deposits of $100 , purchase of $86.72 with overdrawn amount $32.55 is equal to $80.73.
