Answer:
(03.01) The domain of a relation is the output (y) values of the relation the input (x) values of the relation a set of points that pair input values with output values x and y values written in the form (x, y)
{-2, -1, 0, 1, 2, 3} representing the domain of the relation.
What is a function?A relation is a function if it has only One y-value for each x-value.
To determine the domain of a relation, we need to identify all possible values for the input or independent variable.
In this case, without any further information, we can look for the set of numbers provided in the answer choices and determine which set includes all possible values for the input.
Looking at the given answer choices:
A. {-1, 0, 1, 3}
B. {-2, 0, 1, 3}
C. {-2, -1, 0, 1, 2, 3}
D. {0, 1, 2, 3}
Since there is no specific information or restrictions mentioned, the most inclusive set that covers all possible values for the input variable is {-2, -1, 0, 1, 2, 3}.
Therefore, {-2, -1, 0, 1, 2, 3}, representing the domain of the relation.

Carlos drives 161 kilometers at a speed of 70 kilometers per hour. For how many hours does he drive?
Answer:
2.3 hours
Step-by-step explanation:
161 divided by 70 = 2.3
if Carlos drives 161 kilometers at a speed of 70 kilometers per hour then it takes 2.3 hours to drive.
What is Speed?Speed is the time rate at which an object is moving along a path,
Given,
Carlos drives 161 kilometers at a speed of 70 kilometers per hour
From the given data distance=161 kilometers
Distance is one hundred sixty one kilometers
Speed=70km/hr.
Speed is seventy kilometer per hour.
Speed=Distance/time
70=161/time
Now cross multiply
time=161/70
Time=2.3hrs
Hence, if Carlos drives 161 kilometers at a speed of 70 kilometers per hour then it takes 2.3 hours to drive.

Based on the graph below, which sequence of transformations is needed to carry ABCD onto its image A'B'CD?
Answer:
The third is correct.
Step-by-step explanation:
Preimage: A(2,3), B(5,6), C(8,6), D(8,3)
Image: A'(-2, 6); B'(-5,3); C'(-8,3); D'(-8,6)
Option 3.
Translation Rotation 180° Clockwise
(x, y-9) (-x,-y)
A(2,3) (2,-6) A' (-2,-6)
B(5,6) (5,-3) B' (-5,3)
C(8,6) (8,-3) C' (-8,3)
D(8,3) (8,-6) D' (-8,6)
Transformation involves changing the position of a shape.
The sequence of transformation is: (d) A translation rule by [tex]\mathbf{(x,y) \to (x, y - 9)}[/tex] and then a 180 degrees clockwise rotation about the origin
The coordinates of the pre-image is:
[tex]\mathbf{A = (2,3)}[/tex]
[tex]\mathbf{B = (5,6)}[/tex]
[tex]\mathbf{C = (8,6)}[/tex]
[tex]\mathbf{D = (8,3)}[/tex]
Of the given sequence of transformations, option (d) is correct.
The proof is as follows.
First, translate ABCD by (x, y - 9)
So, we have:
[tex]\mathbf{(x,y) \to (x, y - 9)}[/tex]
[tex]\mathbf{(2,3) \to (2, -6)}[/tex]
[tex]\mathbf{(5,6) \to (5, -3)}[/tex]
[tex]\mathbf{(8,6) \to (8, -3)}[/tex]
[tex]\mathbf{(8,3) \to (8, -6)}[/tex]
Next, rotate by 180 degrees.
The rule of this transformation is:
[tex]\mathbf{(x,y) \to (-x,-y)}[/tex]
So, we have:
[tex]\mathbf{(2,-6) \to (-2,6)}[/tex]
[tex]\mathbf{(5,-3) \to (-5,3)}[/tex]
[tex]\mathbf{(8,-3) \to (-8,3)}[/tex]
[tex]\mathbf{(8,-6) \to (-8,6)}[/tex]
From the graph, the coordinates of the image are:
[tex]\mathbf{A" = (-2, 6)}[/tex]
[tex]\mathbf{ B" = (-5,3)}[/tex]
[tex]\mathbf{C" = (-8,3)}[/tex]
[tex]\mathbf{D" = (-8,6)}[/tex]
Hence, the sequence of transformation is:
(d) A translation rule by [tex]\mathbf{(x,y) \to (x, y - 9)}[/tex] and then a 180 degrees clockwise rotation about the origin

Jerrod found the hypotenuse of a right triangle with legs 3 ft and 1 ft. Is his answer correct?
c2 = 32 + 12
c2 = 9 + 1
c2 = 8
c = 8
No, he setup the Pythagorean theorem incorrectly.
No, he made an error finding the square root.
No, he subtracted 1 and 9 instead of adding.
Yes, he correctly calculated the length of the hypotenuse
Answer:
The answer is no he is not correct, here's why.
C) No, he subtracted 1 and 9 instead of adding.
Step-by-step explanation:
Jerrod has found the hypotenuse, with the legs of 3 ft and 1 ft, his process is:
[tex]c^{2}[/tex] = 32 + 12
[tex]c^{2}[/tex] = 9 + 1
[tex]c^{2}[/tex] = 8
c = 8
The legs Jerrod said are 3 ft and 1 ft
so A and B of the formula of pythagorean theorem could be:
[tex]a^{2}[/tex] = (3)[tex].^{2}[/tex]
[tex]b^{2}[/tex] = (1)[tex].^{2}[/tex]
This leads us to:
[tex]3^{2} + 1^{2} = c^{2}[/tex]
which is:
9 + 1 = [tex]c^{2}[/tex]
10 = [tex]c^{2}[/tex]
In this case, Jerrod had calculated wrong by instead of adding he had subtracted.
(I don't know where he got 32 + 12, but other than that his process is correct other than calculation error)
The correct statement for given situation is,
⇒ No, Jerrod made an error to finding the square root.
What is mean by Triangle?Any triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
We have to given that;
Jerrod found the hypotenuse of a right triangle with legs 3 ft and 1 ft.
With steps are,
⇒ c² = 3² + 1²
⇒ c² = 9 + 1
⇒ c² = 8
⇒ c = 8
Now,
We have the steps are,
⇒ c² = 3² + 1²
⇒ c² = 9 + 1
⇒ c² = 8
⇒ c = 8
Clearly, In fourth step we get;
If c² = 8
Then, c = √ 8
But here we have;
⇒ c² = 8
⇒ c = 8
Hence, He made an error finding the square root.
Therefore, The correct statement for given situation is,
⇒ No, Jerrod made an error to finding the square root.

A bird goes from a higher location to a lower location at a
rate of 2 meters per second,
Which equation models the change in the bird's position at 30 seconds?
A. (-30)(-2) = -60
B. 30(-2) = -60
C. 30.2 = 60
D. 30(-2) = 60
Answer:
30(-2) = -60
Step-by-step explanation:
The change in speed from a higher location to a lower location is 2 m/s, v = -2 m/s (from higher to lower)
We need to find the equation that models the change in the bird's position at 30 seconds.
Distance = speed × time
change in position = (-2) × 30
= -60
Hence, the correct option is (B).

A sample of paint contains 3 ounces of blue paint and 8 ounces of yellow paint. If you have a 24 ounce can of the blue paint, how much yellow paint should you mix with it in order to make the same color as the sample? (Your answer should have numbers and units)
Answer:
64 ounces
Step-by-step explanation:
Given.
Represent blue with b and yellow with y
b = 3
y = 8
Required
What's the value of y when b = 24
Represent the given and required parameters as ratio
3 : 8 and 24 : y
Turn the ratio to an equation
3 : 8 = 24 : y
Represent as fraction
⅜ = 24/y
Multiply both sides by y
⅜y = 24
Make y the subject
y = 24 * 8/3
y = 64
Hence:
64 ounces of yellow paints is required for 24 ounces of blue paints

In a group of 28 students, 6 study both Art and Biology.
1 studies Biology but not Art.
1 studies neither subject.
Given that a randomly selected student studies Art, what is the probability the student studies Art and Biology?
Answer:
3/13
Step-by-step explanation:
There are 28 students. 1 studies biology but not art. 1 studies neither subject. Therefore, there are 26 students who study art.
Of the 26 students who study art, 6 also study biology. So the probability is 6/26, which reduces to 3/13.

the complex solutions of which equation have a real component of 4.
(I'm not sure of what this is asking.)
Answer:
A.
Step-by-step explanation:
I just did this problem and guessed correctly.
The complex solutions of which equation have a real component of 4 is x² - 8x +16 +21 = 0.
What is Complex number?Complex numbers are numbers that consist of two parts — a real number and an imaginary number.
On solving all equation the correct one is x² - 8x +16 = -21.
Using discriminant method calculating the roots
x² - 8x +16 +21 = 0
x² - 8x + 37 = 0
x= -b ± √b² -4ac / 2a
x= 8 ± √ -8² - 4*1 * (37) /2a
x= 8 ± √- 84 / 2
x= 8 ± √2² *(- 21) /2
x=( 8 ± √2² *√21 i)/2
x= 8 / 2 ± 2i√21/2
x= 4 ± √21 i
So, x = 4+ √21 i and x= 4 - √21 i
