Without explicit graphical representation, precise classification is challenging. Tentatively: Graph A could be a non-linear function, Graph B is not a function due to its circular form, and Graph C could be a linear function (or a piecewise linear function) as a 'V' indicates straight lines.
Explanation:In Mathematics, when we talk about functions, a linear function is one where the graph is a straight line. A non-linear function is anything that is not a linear function, including any graph that is not a straight line. If a graph does not pass the vertical line test, where any vertical line would touch the graph only once, it is considered not a function.
Based on the descriptions given:
Graph A, being the 'first graph,' isn't sufficient information for classification. However, as a placeholder, let's say it's a non-linear function.Graph B, being a circle, does not pass the vertical line test and is therefore not a function.Graph C, if shaped like a 'V,' would be a linear function, as it forms straight lines. However, if the point at which the 'V' changes direction occurs at a single point, it could be argued as a piecewise linear function.Learn more about Function Identification here:https://brainly.com/question/33409105

How to categorize the graphsGraph A represents a non-linear function due to its curved shape, showcasing a relationship where the output doesn't change uniformly with respect to the input.
Graph B, resembling a circle, doesn't represent a function as it fails the vertical line test, indicating multiple outputs for a single input.
Graph C, displaying a V-shape, represents a linear function, depicting a consistent rate of change between the variables.
Linear functions maintain a constant slope, resulting in a straight line. Therefore, these classifications are based on the distinctive characteristics of the graphs concerning linearity and functional behavior.

Answers
Answer:
2 minutes 40 sec
Step-by-step explanation:
Recall that distance = rate times time.
Thus, time = distance / rate.
Here,
time = 280 ft / (1.75 ft/sec) = 160 sec, or 2 minutes 40 sec
To calculate the time it takes to travel 280 feet on a moving walkway at an airport moving at a pace of 1.75 feet per second, we use the formula time = distance/pace. This equates to approximately 160 seconds.
Explanation:The question is asking about the time it takes to transport someone along a distance of 280 feet by a moving walkway in an airport, given that the pace of the walkway is 1.75 feet per second.

Given cos a= 3/5, sin B = 5/13 and a and B are first quadrant angles find cos(a + B)
A. 1/3
B. 16/65
C. -33/65
Please explain
Answers
Answer:
Option B is correct.
Value of cos(a+B) is, [tex]\frac{16}{65}[/tex]
Step-by-step explanation:
Using the formula:
[tex]\cos(a+B) = \cos a \cos B -\sin a \sin B[/tex]
Given the values:
[tex]\cos a = \frac{3}{5}[/tex] and [tex]\sin B = \frac{5}{13}[/tex]
Using trigonometric identity:
[tex]\sin^2 \theta + \cos^2 \theta =1[/tex]
or
[tex]\sin \theta = \sqrt{1-\cos^2 \theta}[/tex]
or
[tex]\cos \theta = \sqrt{1-\sin^2 \theta}[/tex]
Find the value of sin a and cos B;
Using trigonometric identity:
[tex]\sin a = \sqrt{1-\cos^2 a}[/tex]
[tex]\sin a = \sqrt{1-(\frac{3}{5})^2}[/tex] = [tex]\sqrt{1-\frac{9}{25}} = \sqrt{\frac{25-9}{25}}=\sqrt{\frac{16}{25} } =\frac{4}{5}[/tex]
Similarly;
[tex]\cos B = \sqrt{1-\sin^2 B}[/tex]
[tex]\cos B = \sqrt{1-(\frac{5}{13})^2}[/tex] = [tex]\sqrt{1-\frac{25}{169}} = \sqrt{\frac{169-25}{169}}=\sqrt{\frac{144}{169} } =\frac{12}{13}[/tex]
Substitute these given values equation [1] we have;
[tex]\cos(a+B) =\frac{3}{5} \cdot \frac{12}{13}-\frac{4}{5} \cdot \frac{5}{13}[/tex]
[tex]\cos(a+B) =\frac{36}{65}-\frac{20}{65}[/tex]
then;
[tex]\cos(a+B) =\frac{36-20}{65}=\frac{16}{65}[/tex]
Since, the angles a and B are in first quadrant angles therefore the value of cos(a+B) is, [tex]\frac{16}{65}[/tex]
To find cos(a + B), use the formula cos(a + B) = cos(a)cos(B) - sin(a)sin(B). Substitute the given values of cos(a) = 3/5 and sin(B) = 5/13, and solve for cos(B) using the Pythagorean identity. Then substitute all the values into the formula and simplify to find cos(a + B) = 16/65.
Explanation:To find cos(a + B), we can use the formula:
cos(a + B) = cos(a)cos(B) - sin(a)sin(B)
Given that cos(a) = 3/5 and sin(B) = 5/13, we can substitute these values into the formula:
cos(a + B) = (3/5)(cos(B)) - (sin(a))(5/13)
To find cos(B), we can use the Pythagorean identity:
cos²(B) + sin²(B) = 1
Substituting the given value of sin(B), we can solve for cos(B):
cos(B) = √(1 - (5/13)²)
Now we can substitute the values of cos(a), sin(B), and cos(B) into the formula for cos(a + B):
cos(a + B) = (3/5)(√(1 - (5/13)²))) - (5/13)(5/13)
Simplifying this expression gives us the final answer: cos(a + B) = 16/65.

If 75 pairs of jeans are sold, what is the company’s profit?
Answers
Answer:
So, the company profit if 75 pairs of jeans are sold is $1450
Step-by-step explanation:
The number of pairs of jeans that have been sold is represented by x
We are given
The profit is the difference between the revenue and the cost , 20x-50
Let's assume profit function as P(x)
[tex]P(x)=20x-50[/tex]
There are 75 pairs of jeans
so, x=75
we can plug x=75 and find profit
[tex]P(75)=20\times 75-50[/tex]
[tex]P(75)=1500-50[/tex]
[tex]P(75)=1450[/tex]
So, the company profit if 75 pairs of jeans are sold is $1450
Given that lines a and b are parallel, what angles formed on line b when cut by the transversal are congruent with ∠3?

B) ∠5 and ∠7
C) ∠6 and ∠7
D) ∠6 and ∠8
Answers
angles that are opposite to each other are congruent.
Answer:
C) ∠6 and ∠7
Step-by-step explanation:
We have been given that lines a and b are parallel. We are asked to find the angle on line b that will be congruent to angle 3.
We can see that angle 3 is under the line a and on the left side of transversal.
We know that the corresponding angles and alternate interior angles formed by two parallel lines are equal.
We can see that angle 7 corresponds to angle 3 and angle 6 is alternate interior angle of angle 3.
Therefore, angle 7 and angle 6 will be congruent with angle 3 and option C is the correct choice.
The coordinates of the vertices of JKL are J(-5, -1), K(0, 1) , and L(2, -5). Which statement correctly describes whether JKL is a right triangle?
Answers
Answer:
It is NOT a right triangle.
Step-by-step explanation:
You must figure out the slopes of the segments of the triangle to see if it is a right triangle. If they are perpendicular (meaning the slopes are negative reciprocals of each other), they form a right angle, making it a right triangle.
[tex]\frac{y_{2} -y_{1}}{x_{2} -x_{1}}[/tex] This formula finds slope using two points.
Let's figure out the slope of JK.
(-1-1)/(-5-0) = m
Simplify.
-2/-5 = m
A negative divided by a negative makes a positive.
2/5 = m
Now LK.
(-5-1)/(2-0) = m
Simplify.
-6/2 = m
Divide.
-3/1 = m
Now JL.
(-1+5)/(-5-2) = m
Simplify.
4/-3 = m
None of these slopes are negative reciprocals of each other, thus deeming it not a right triangle.

Answers
Answer:
3. The number of months Megan will wait to sell the gadget.
Step-by-step explanation:
We have been given that Megan purchased a new gadget for her technology hobby. She plans to sell it sometime in the future, however, its value depreciates monthly.
The expression below shows the depreciated sales value of the gadget: [tex]2020-22m[/tex]
From above expression we can see that gadget's original value is $2020 and its value falls by $22 every month and m represents the number of months after which Megan will sell her gadget.
Therefore, the variable m represents the number of months Megan will wait to sell the gadget and 3rd option is the correct choice.
The variable m represents the number of months Megan will wait to sell the gadget and 3rd option is the correct choice. The variable m in the expression 2020 – 22m represents the number of months Megan will wait to sell the gadget.
The original value of the gadget is 2020, and the monthly depreciation value is 22.
So, the expression 2020 – 22m represents the amount of money Megan will get when she sells the gadget after m months.
If Megan waits for 0 months to sell the gadget, then m = 0 and she will get
2020 – 22 * 0 = $2020.
If Megan waits for 1 month to sell the gadget, then m = 1 and she will get
2020 – 22 * 1 = $1998.
Therefore, the variable m in the expression 2020 – 22m represents the number of months Megan will wait to sell the gadget.

What are the x–coordinates of the three points where the graphs of the equations intersect? x3 – 10x = x2 – 6
Answers
Answer:
(- 3, 0), (2 + [tex]\sqrt{2}[/tex], 0), (2 - [tex]\sqrt{2}[/tex], 0)
Step-by-step explanation:
rearrange the equation equating to zero
x³ - x² - 10x + 6 = 0
note that when x = - 3
(- 3)³ - (- 3)² - 10(- 3) + 6 = - 27 - 9 + 30 + 6 = 0, hence
x = - 3 is a root and (x + 3) is a factor of the polynomial
dividing x³ - x² - 10x + 6 ÷ (x + 3) gives
(x + 3)(x² - 4x + 2) = 0
solve x² - 4x + 2 = 0 using the quadratic formula
with a = 1, b= - 4 and c = 2
x = (4 ± [tex]\sqrt{16-(4(1)(2)}[/tex])/ 2
= (4 ± [tex]\sqrt{8}[/tex]) / 2
= (4 ± 2[tex]\sqrt{2}[/tex]) / 2

Answer: [tex]\bold{x=-3,\quad x=2+\sqrt{2}, \quad x=2-\sqrt{2} }}[/tex]
Step-by-step explanation:
First, move all terms to one side with zero on the other side so the Zero Product Property can be applied:
x³ - x² - 10x + 6 = 0 Possible rational roots are: ±{1, 2, 3, 6}
Use synthetic division to find one of the roots. Let's try x = -3
-3 | 1 -1 -10 6
| ↓ -3 12 -6
1 -4 2 0 ← remainder is zero, so x = -3 is a root/intercept
Next, evaluate the reduced polynomial x² - 4x + 2 = 0
This can not be factored so use the quadratic formula to find the remaining roots/intercepts: [tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
a = 1, b = -4, c = 2
[tex]x=\dfrac{-(-4)\pm\sqrt{(-4)^2-4(1)(2)}}{2(1)}[/tex]
[tex]=\dfrac{4\pm\sqrt{16-8}}{2}[/tex]
[tex]=\dfrac{4\pm\sqrt{8}}{2}[/tex]

Given: ABCD is a trapezoid, AB=CD, MN is a midsegment, MN=30, BC=17, AB=26 Find: m∠A, m∠B, m∠C, and m∠D
Answers
Answer:
m∠A=m∠D=60°, m∠B=m∠C=120°
Step-by-step explanation:
Consider isosceles trapezoid ABCD with midsegment MN. Draw two trapezoid heights BF and CE. Then quadrilateral FBCE is rectangle and EF=BC=17 units.
By the trapezoid midsegment theorem,
[tex]MN=\dfrac{AD+BC}{2},\\ \\30=\dfrac{AD+17}{2},\\ \\60=AD+17,\\ \\AD=60-17=43\ units.[/tex]
Segments FA and ED are equal to [tex]\dfrac{43-17}{2}=13\ units.[/tex]
In right triangle ABF, the hypotenuse AB is twice greater than the leg FA, then m∠FBA=30°.
m∠B=m∠FBA+m∠CBF=30°+90°=120°.
In isosceles trapezoid
m∠B=m∠C=120°,
m∠A=m∠D and m∠A=180°-m∠B=180°-120°=60°=m∠D.
In a trapezoid with equal bases and a midsegment, the angle measures of the trapezoid can be determined using the properties of the figure. In this case, the angle measures are 90 degrees for each angle.
Explanation:In a trapezoid ABCD, the midsegment MN is parallel to the bases AB and CD, and its length is equal to the average of the lengths of the bases. Given that AB = 26, CD = 26, and MN = 30, we can set up the equation: MN = (AB + CD) / 2. Substituting the given values, we get 30 = (26 + 26) / 2. Solving for the angle measures, we can use the fact that the opposite angles in a trapezoid are congruent. So, m∠A = m∠C and m∠B = m∠D. Since the sum of the interior angles of a trapezoid is always 360 degrees, we can use the equation: m∠A + m∠B + m∠C + m∠D = 360. Substituting the angle measures we found, we get 2(m∠A) + 2(m∠B) = 360. Solving for the angle measures, we get m∠A = m∠C = 90 degrees and m∠B = m∠D = 90 degrees.

Answers
Answer:
The probability that both spinners will land on 2 is A) 1/12.
Step-by-step explanation:
To get this answer you must:
-First, take the total number of outcomes and set that as you denominator, which would be 3.
-Since, your looking for the probability of two, and there is only one two you would put one as your numerator. By now you should have a fraction of: 1/3.
-Next, do the same exact thing for the next graph. Take the total number of outcomes for the graph which is 4, and set that as your denominator.
-Then, set one as your numerator since there is only one two in the other graph. You should now have a second fraction of: 1/4.
-Lastly, multiply both of the fractions. Multiply both of the numerator together and you should get one. Then, multiply both of the numbers which would result in you getting a number of 12.

What is the sum of the first seven terms of the geometric series? 3 + 12 + 48 + 192 + ... 4,372 12,288 16,383 65,535
Answers
Answer:
16,383 or C
Step-by-step explanation:
Answer:
Option 3rd is correct.
Step-by-step explanation:
Given: 3 + 12 + 48 + 192 + .......
We have to find : Sum of first seven term of the given Geometric series.
First term , a = 3
Common ratio , r = [tex]\frac{12}{3}=4[/tex]
Sum of the n term of series, [tex]S_n=\frac{a(1-r^n)}{1-r}[/tex]
So,
[tex]S_7=\frac{3(1-4^7)}{1-4}[/tex]
[tex]S_7=\frac{3(1-4^7)}{-3}[/tex]
[tex]S_7=-(1-16384)[/tex]
[tex]S_7=-(-16383)[/tex]
[tex]S_7=16383[/tex]
Therefore, Option 3rd is correct.
