not a function
Answer:
a. Function
b. Function
c. Not a function
Step-by-step explanation:
Here is a basic rule to determine if a relation is a function of not:
1. A function has only one exact y-value (range) assigned to each x-value (domain).
2. A x-coordinate value is not repeated in a function, however, a y-coordinate value can be repeated. This means, the same y-value can be assigned to different x-values.
Bearing these in mind, let's label the given representation accordingly:
a. There is exactly one y-value assigned to each x-value, and also, no x-value is repeated. Therefore, it is a function.
b. The graph shows a repeating y-value, however, each x-value has exactly one y-value assigned to it. Therefore the graph represented is a function.
c. The table shows a repeating x-values. This is definitely not a function.

Answer:
(a) 3, (b) 96, (c) No
Step-by-step explanation:
(a) Since we have [tex]p = 150 - 6q^2[/tex] and [tex]p = 10q^2 + 2q[/tex], we can set up a quadratic equation by [tex]150 - 6q^2 = 10q^2 + 2q[/tex], moving all values to one side.
The equation is: [tex]16q^2 + 2q - 150 = 0[/tex].
Let's use the quadratic formula to find q,
we obtain that [tex]q = 3[/tex] or [tex]q = -3.125[/tex]
We can ignore [tex]-3.125[/tex] because supplying a negative quantity is impossible.
Hence, the answer of (a) is 3
(b) Simply substitute [tex]q = 3[/tex] into either equations given in the question to find p, and the answer of (b) is 96.
(c) We want to find if there is an exact quantity that makes the TR exactly 1500.
We substitute TR = 1500,
[tex]1500 = 85q - 2q^2[/tex]
Use the quadratic formula again, and we will find that the answer is "undefined".
As a result, there is not output level in which the total revenue is exactly 1500.

Answer:
(A) the addition property of equality and then the division property of equality
Step-by-step explanation:
To get from Step 1 to Step 2, we have added 5 to both sides of the equation:
-3x -5 +5 = 13 +5
-3x = 18
To get from Step 2 to Step 3, we have divided both sides of the equation by -3:
-3x/-3 = 18/-3
x = -6
These operations can be described as ...
the addition property of equality and then the division property of equality

However, since addition and subtraction are the same thing, but with opposite numbers, and since multiplication and division are the same thing, but with reciprocal numbers, any of the answer choices is arguably correct.
(add 5, divide by -3) = (add 5, multiply by -1/3) =
(subtract -5, divide by -3) = (subtract -5, multiply by -1/3)

Andrew and his children went into a grocery store and he bought $12 worth of
apples and bananas. Each apple costs $1 and each banana costs $0.60. He
bought a total of 16 apples and bananas altogether. By following the steps
below, determine the number of apples, x, and the number of bananas, y,
that Andrew bought.
The number of apples and bananas andrew and his children bought is 6 and 10 respectively.
Andrew and his children bought $12 worth of apples and bananas. Each apple costs $1 and each banana costs $0.60. He bought a total of 16 apples and bananas altogether.
Let number of apples = x and number of bananas is x-16
In mathematics it deals with numbers of operations according to the statements.
Here,
x*4 + 0.60(16-x) = 12
0.4x + 9.6 = 12
0.4x = 2.4
Number of apples, x = 6
And number of bananas = 16 -x
= 16 - 6
= 10
Thus, the number of apples and bananas andrew and his children bought is 6 and 10 respectively.

New legislation passed in 2017 by the U.S. Congress changed tax laws that affect how many people file their taxes in 2018 and beyond. These tax law changes will likely lead many people to seek tax advice from their accountants (The New York Times). Backen and Hayes LLC is an accounting firm in New York state. The accounting firms believe that it may have to hire additional accountants to assist with the increased demand in tax advice for the upcoming tax season. Backen and Hayes LLC has developed the following probability distribution for x= number of new clients seeking tax advice.x f(x)20 .0525 .2030 .2535 .1540 .1545 .1050 .10a. Is this a valid probability distribution? Explain.b. What is the probability that Backens and Hayes LLC will obtain 40 or more new clients?c. What is the probability that Backens and Hayes LLC will obtain fewer than 35 new clients?d. Compute the expected value, variance, and standard deviation of x.
Answer:
a. Yes
b. 0.35
c. 0.5
d.
E(x)=34.25
V(x)=73.1875
SD(x)=8.555
Step-by-step explanation:
a.
x 20 25 30 35 40 45 50
f(x) 0.05 0.2 0.25 0.15 0.15 0.1 0.1
This will be valid probability distribution if
1. All probabilities are between 0 and 1 inclusive.
2. Sum of probabilities must be 1.
Condition 1 is satisfied in this distribution. Now, we will check second condition
sum(f(x))=0.05+0.2+0.25+0.15+0.15+0.1+0.1=1.
As the both conditions are satisfied, thus the given distribution is a valid probability distribution.
b.
P(x≥40)=P(X=40)+P(X=45)+P(X=50)
P(x≥40)=0.15+0.1+0.1
P(x≥40)=0.35
So, the probability that Backens and Hayes LLC will obtain 40 or more new clients is 0.35.
c.
P(x<35)=P(X=20)+P(X=25)+P(X=30)
P(x<35)=0.05+0.2+0.25
P(x<35)=0.5
So, the probability that Backens and Hayes LLC will obtain fewer than 35 new clients is 0.5.
d.
Expected value of x=E(x)= sum[x*f(x)]
E(x)= 20*0.05+25*0.2+30*0.25+35*0.15+40*0.15+45*0.1+50*0.1
E(x)=1+5+7.5+5.25+6+4.5+5
E(x)=34.25
Variance of x=V(x)=sum[x²*f(x)]-(sum[x*f(x)])²
sum[x²*f(x)]= 20²*0.05 +25²*0.2 +30²*0.25 +35²*0.15 +40²*0.15 +45²*0.1 +50²*0.1
sum[x²*f(x)]=20+1255+225+183.75+240+202.5+50
sum[x²*f(x)]=1246.25
V(x)=1246.25-(34.25)²
V(x)=73.1875
Standard deviation of x=SD(x)=√V(x)
SD(x)=8.555

The function is defined as follows for the domain given.
f(x)=3x+2, domain = (-2,-1,0, 1}
What is the range?
Answer:
- 4, - 1, 2, 5
Step-by-step explanation:
To find the range, simply substitute each of the domains into the function to get the y-values.
f(-2) = 3(-2) + 2
= - 6 + 2
= - 4
f(- 1) = 3(-1) + 2
= - 3 + 2
= - 1
f(0) = 3(0) + 2
= 0 + 2
= 2
f(1) = 3(1) + 2
= 3 + 2
= 5
The range is - 4, -1, 2, 5.

Ashley is diving in the ocean. She wants to reach a coral reef that is 60 feet below sea level; that is, the reef’s elevation is -60 feet. She decides to safely descend to the reef from the ocean’s surface in increments of 10 feet. Answer the following questions to learn more about Ashley’s rate of descent
Part B
Write a numerical expression that represents the number of increments it will take Ashley to reach -60 feet.
Part C
Is the number of increments in part B positive or negative?
Part D
Rewrite the expression from part B by distributing -1 from each of the negative numbers.
Part E
If you divide any number by itself, what is the result? How can you apply this result to the expression in part D?
Part F
Based on your work so far, how many increments of -10 feet are in -60 feet?
Part G
Copy and paste this image into the space below the correct number of times to show an elevation of -60 feet.
Part H
Suppose that Ashley’s brother, Alex, makes the same dive in 4 increments instead of 6 Write a numerical expression to represent Alex’s elevation change in feet per increment.
Part I
How many negative numbers are in the expression in part H? What will the sign of the solution be? How do you know?
Part J
What was Alex’s elevation change in feet per increment?
Answer:
Part B: is -60 divided by -10
Part C: is The number of increments is positive.
Part D: is -1 times 60 / -1 times 10
Part E: is Any number divided by itself is 1. In the expression -1 times 60, the -1s in the numerator and the denominator cancel each other out to give the result 60/10, or 6
Part F: is There are 6 increments of -10 feet in -60 feet.
Part G is: copy and paste -10 feet 6 times
Part H: is -60 / 4 increments
Part I: is there is one negative number in the expression, so the solution will be negative. There isn't a -1 in the denominator to cancel out the -1 in the numerator.
Part J: is -60 /4 =-15 Alex’s elevation change in each increment was -15 feet.
Step-by-Step Explaination: I did the test.
Answer:
A:-10 or -10 feet
B:-60/-10 or -60 feet/-10 feet
C: The number of increments is positive.
D: -1 X 60/ -1 X 10 or -1 X 60 feet/ -1 X 10 feet
E: Any number divided by itself is 1. In the expression -1 X 60, the -1s in the numerator and the denominator cancel each other out to give the result 60/10, or 6.
F: There are 6 increments of -10 feet in -60 feet
G: copy and paste 6X
H:-60 feet / 4 increments
I: There is one negative number in the expression, so the solution will be negative. There isn't a -1 in the denominator to cancel out the -1 in the numerator.
J:-60/4 = -15 Alex's elevation change in each increment was -15 feet

Answer:
#2) 6,440 kilograms
The density of steel is 8,050 kilograms per cubic meter. A construction company is using a steel beam in the shape of a rectangular prism that measures 12 meters long, 1/5 of a meter wide, and 1/3 meter deep then the mass of the steel beam is 6,440 kilograms Option b.
To find the mass of a steel beam.
Let's start by defining the variables we have:
- The density of steel, denoted by "ρ" (rho), is given as 8,050 kilograms per cubic meter (kg/m³).
- The dimensions of the steel beam are:
- Length (L) = 12 meters (m)
- Width (W) = 1/5 meter (m)
- Depth (D) = 1/3 meter (m)
We want to find the mass (m) of the steel beam. The mass of an object can be calculated using its density and volume:
M = ρ [tex]\times V[/tex]
Here, "V" represents the volume of the steel beam. The volume of a rectangular prism (like the steel beam) is calculated as:
[tex]\[ V = L \times W \times D \][/tex]
Substitute the given values:
[tex]\[ V = 12 \, \text{m} \times \frac{1}{5} \, \text{m} \times \frac{1}{3} \, \text{m} \][/tex]
[tex]\[ V = 12 \, \text{m} \times \frac{1}{5} \times \frac{1}{3} \, \text{m} \][/tex]
[tex]\[ V = \frac{12}{5} \times \frac{1}{3} \, \text{m}^3 \][/tex]
[tex]\[ V = \frac{12}{15} \, \text{m}^3 \][/tex]
[tex]\[ V = \frac{4}{5} \, \text{m}^3 \][/tex]
Now that we have the volume, we can find the mass of the steel beam using the given density:
[tex]\[ m = 8,050 \, \text{kg/m}^3 \times \frac{4}{5} \, \text{m}^3 \][/tex]
[tex]\[ m = \frac{8,050 \times 4}{5} \, \text{kg} \][/tex]
[tex]\[ m = \frac{32,200}{5} \, \text{kg} \][/tex]
[tex]\[ m = 6,440 \, \text{kg} \][/tex]
After performing the calculations, we find that the mass of the steel beam is 6,440 kilograms. Therefore, the correct answer is option Option b 6,440 kilograms.

∠ A ≈ 43.1°
Step-by-step explanation:
Using the Sine rule in Δ ABC , that is
[tex]\frac{a}{sinA}[/tex] = [tex]\frac{c}{sinC}[/tex] , substitute values
[tex]\frac{20}{sinA}[/tex] = [tex]\frac{29}{sin82}[/tex] ( cross- multiply )
29 × sinA = 20 × sin82 ( divide both sides by 29 )
sinA = [tex]\frac{20sin82}{29}[/tex] , thus
∠ A = [tex]sin^{-1}[/tex] ([tex]\frac{20sin82}{29}[/tex] ) ≈ 43.1° ( to 1 dec. place )
