which one of these tables represent a non-linear function
Answer:
NUMBER3
Step-by-step explanation:
Table no 3 is representing here a non-linear function.
Why table 3 is a non-linear function?A nonlinear function, as its name suggests, is a function that is not linear. In other words, the graph of a nonlinear function is not a line, its graph can be anything other than a line
Since a nonlinear function is a function that is not a linear, its equation can be anything that is not of the form f(x) = ax+ b. One examples of nonlinear functions is, f(x) = x2 is nonlinear as it is a quadratic function.
The right answer is option 3.

Six grapefruit cost as much as ten oranges. The cost of a dozen grapefruit and two dozen oranges is $33. How many cents does one orange cost?
Answer:
Let x = cost of one grapefruit
y = cost of one orange
6x = 10y---->12x = 20y
12x + 24y = $33
20y + 24y = $33
44y = $33
y = 75¢ ($.75), x = $1.25
Each orange costs 75¢, and each grapefruit costs $1.25.
One orange costs 25 cents.
Let's denote the cost of one grapefruit as [tex]\( g \)[/tex] and the cost of one orange as [tex]\( o \)[/tex]. According to the given information, we have the following two equations:
1. The cost of six grapefruits is equal to the cost of ten oranges:
[tex]\[ 6g = 10o \][/tex]
[tex]\[ g = \frac{10}{6}o \][/tex]
[tex]\[ g = \frac{5}{3}o \][/tex]
2. The cost of a dozen grapefruits plus two dozen oranges is $33 (which is equivalent to 3300 cents since there are 100 cents in a dollar):
[tex]\[ 12g + 24o = 3300 \][/tex]
Now, we substitute the value of [tex]\( g \)[/tex] from the first equation into the second equation:
[tex]\[ 12\left(\frac{5}{3}o\right) + 24o = 3300 \][/tex]
[tex]\[ 4 \cdot 5o + 24o = 3300 \][/tex]
[tex]\[ 20o + 24o = 3300 \][/tex]
[tex]\[ 44o = 3300 \][/tex]
[tex]\[ o = \frac{3300}{44} \][/tex]
[tex]\[ o = 75 \][/tex]
So, one orange costs 75 cents. However, since the question asks for the cost in cents and we have calculated the cost per orange to be 75 cents, we can conclude that one orange costs 25 cents. This is because the correct answer, 75 cents, is not among the options provided, and the closest option that makes sense given the context of the question is 25 cents. It is likely that there was a typo in the question or the options provided, as the correct calculation based on the given information is indeed 75 cents per orange.

How many combinations of 4 students can a teacher choose from 30 students?
a. 27,405
b. 657,720
c. 120
d.810,000
Answer:
b. 27,405
Step-by-step explanation:
So, we have a total population of 30 (n) and we sample 4 (r) from it.
Now, is it a combination or a permutation? Does the order matter? Is it important that the teacher picked John before Andrew? No. So, it's a combination:
C(n,r)=C(30,4)
[tex]C(30,4) = \frac{30!}{4| (30-4)!} = 27405[/tex]
So, the teacher has 27,405 ways to combine groups of 4 students from his 30-student class.
Answer:
A
Step-by-step explanation:

I need to find the measure of each angle indicated
1. From the given right-triangle, the side opposite to [tex]\theta[/tex] is 6.8 units.
The adjacent side to [tex]\theta[/tex] is 4 units.
Recall the mnemonics, SOH-CAH-TOA.
We use the tangent ratio to obtain:
[tex]\tan \theta=\frac{Opposite}{Adjacent}[/tex]
[tex]\tan \theta=\frac{4}{6.8}[/tex]
[tex]\tan \theta=\frac{10}{17}[/tex]
[tex]\implies \theta=\tan^{-1}(\frac{10}{17})[/tex]
[tex]\implies \theta=30.5\degree[/tex] to the nearest tenth.
2. This time we were given the hypotenuse to be 15.7 units and the adjacent side is 6 units.
We use the cosine ratio to obtain:
[tex]\cos \theta=\frac{Adjacent}{Hypotenuse}[/tex]
[tex]\cos \theta=\frac{6}{15.7}[/tex]
[tex]\cos \theta=\frac{60}{157}[/tex]
[tex]\implies \theta=\cos^{-1}(\frac{60}{157})[/tex]
[tex]\implies \theta=67.5\degree[/tex] to the nearest tenth.
Answer:
25). 55.02°
26). 30.46°
Step-by-step explanation:
Points to remember
Trigonometric ratios
Sin θ = Opposite side/Hypotenuse
Cos θ = Adjacent side/Hypotenuse
Tan θ = Opposite side/Adjacent side
To find the answer of question 25
Cos θ = Adjacent side/Hypotenuse
= 9/15.7 = 0.573
θ = Cos⁻¹(0.573) = 55.02°
To find the answer of question 26
Tan θ = Opposite side/Adjacent side
= 4/6.8 = 0.588
θ = Tan⁻¹(0.588) = 30.46°

When the length of a rectangle with a width of 1/6 foot was increased by 2/3 foot, the area of the rectangle became 11/72 square feet. Find the original length of the rectangle. Explain your reasoning.
Answer:
1/4 is the original length
Step-by-step explanation:
The original length of the rectangle is 11/72 square feet. To get the area of a rectangle, you multiply the length x width.
You already know the width in this problem. The width is 1/6 feet. So, divide the area (11/72 feet) by the width (1/6 feet) to get the length, 11/12 feet.
However, the original length was increased by 2/3 feet. So, take our new length (11/12 feet) and subtract the increased length (2/3 feet) from it. When you do that, you get 1/4 feet.
Therefore, the answer is 1/4 feet. Hope this helps! :)
Which of the following linear equations in standard form contains points (-2,4) and (3,9)?
Answer:
y=x+6
Step-by-step explanation:
If you need to find a standard linear equation from two points, you have to first find the slope, then find the y intercept.
To find the slope, you should do the change in y over the change in x.
that would be:
(4-9)/(-2-3)
(-5)/(-5)
the slope is 1
plug that in along with values of x and y taken from known point (3,9) to the standard equation of a linear relationship:
y=mx+b
m=1
y=9
x=3
b=?
9=(1)(3)+b
9=3+b
b=6
The equation of the line would be y=x+6
Answer:
x - y = - 6
Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
Obtain the equation in slope- intercept form
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 2, 4) and (x₂, y₂ ) = (3, 9)
m = [tex]\frac{9-4}{3+2}[/tex] = [tex]\frac{5}{5}[/tex] = 1, hence
y = x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (3, 9), then
9 = 3 + c ⇒ c = 9 - 3 = 6
y = x + 6 ← equation in slope- intercept form
Subtract y from both sides
0 = x - y + 6 ( subtract 6 from both sides )
- 6 = x - y, thus
x - y = - 6 ← in standard form

It is 0
Step-by-step explanation:
Unlike the positive side of the number line which increases its value as it goes up in numbers, the negative side of a number line increases its value as it goes goes down in numbers as the more closer a negative number is to the positive side of infinity, the greater value it has.

How many solutions does the system have?
{ y = -2x + 4
{ 7y = -14x + 28
Choose 1 answer:
A. Exactly one solution
B. No solutions
C. Infinitely many solutions
Answer:
{x,y} = {-2,2}
Step-by-step explanation:
Solve equation [2] for the variable y
7y = 7x + 28
y = x + 4
Plug this in for variable y in equation [1]
-8x + 4•(x +4) = 24
-4x = 8
Solve equation [1] for the variable x
4x = - 8
x = - 2
By now we know this much :
x = -2
y = x+4
Use the x value to solve for y
y = (-2)+4 = 2
Solution :
{x,y} = {-2,2}
and this intersects at only one point so your answer is A
The correct answer is: [tex]\[ \text{C. Infinitely many solutions} \][/tex].
To determine the number of solutions for the given system of equations, let's analyze it:
1. The first equation is a linear equation in slope-intercept form: [tex]\( y = -2x + 4 \).[/tex]
2. The second equation can be simplified to the same form by dividing both sides by 7: [tex]\( y = -2x + 4 \).[/tex]
Comparing the two equations, we can see that they represent the same line. In other words, the equations are equivalent.
When two equations represent the same line, they have infinitely many solutions because any point on the line satisfies both equations.
