Answer:
The correct answer is true because functions are exponential. (2,3)
The pair of functions that satisfies your question is y = 2x 2 and y = 2 x.
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) (the dependent variable). In mathematics and the physical sciences, functions are indispensable for formulating physical relationships.
Linear function is a function whose graph is a straight line
We are given that;
Interval= 0 x 5
Now,
The exponential function is growing faster than the quadratic function over the interval 0 x 5, because it is above it for most of the interval.
Here is a table of values for these functions:
x y = 2x 2 y = 2 x
0 0 1
1 2 2
2 8 4
3 18 8
4 32 16
5 50 32
The y-values for the exponential function are larger than the y-values for the quadratic function for all x-values except x = 0.
Therefore, by the function the answer will be y = 2x 2 and y = 2 x.

A merchant gains 20 %by selling an article for rs 480. what percent would he have gained or lost if he had sold it for rs 430
Answer: 7.5% gain
Step-by-step explanation:
First find the original price of the article.
Assume this price to be x.
x + (x * 20%) = 480
x + 0.2x = 480
1.2x = 480
x = 480/1.2
x = Rs. 400
Original price is Rs. 400.
If the merchant had sold the article for 430, the percent gain would have been:
= (Selling price - original price) / Original price
= (430 - 400) / 400
= 7.5%

A straight line has a slope of 2.08. Calculate the angle that the line makes with the x (horizontal) axis.
Answer:
The angle that the line makes with x-axis of of 64.3º.
Step-by-step explanation:
Equation of a line, and angle with the x axis:
The equation of a line has the following format:
[tex]y = mx + b[/tex]
In which m is the slope.
The angle that the line makes with the x axis is given by the angle which has tangent m, that is, [tex]a = \tan^{-1}{m}[/tex].
In this question:
We have that [tex]m = 2.08[/tex]. So
[tex]a = \tan^{-1}{2.08} = 64.3[/tex]
The angle that the line makes with x-axis of of 64.3º.

how would the expression x^3-8 be rewritten using difference of cubes?
A- (x+2)(x^2+2x-4)
B- (x-2)(x^2-2x+4)
C-(x+2)(x^2-2x+4)
D-(x-2)(x^2+2x+4)
Answer:
D
Step-by-step explanation:
Difference of cubes is as follows
x^3-y^3=(x-y)(x^2+y^2+xy)
*notice how the sign in the origonal equation is the same for the first part but then flipped for the second*****
8 can be rewritten as 2^3 so we have
x^3-2^3 which means that we can use the template from before
(x-2)(x^2+2^2+2x)
simplify the 2^2 into 4 and put the variables in front to get
(x-2)(x^2+2x+4)
This is the same as D

What are the solutions to –2x+ 2 = (3) +1?
Answer:
x=1
Step-by-step explanation:
Let's solve your equation step-by-step.
2x+2=3+1
Step 1: Simplify both sides of the equation.
2x+2=3+1
2x+2=(3+1)(Combine Like Terms)
2x+2=4
2x+2=4
Step 2: Subtract 2 from both sides.
2x+2−2=4−2
2x=2
Step 3: Divide both sides by 2.
2x2=22
x=1

Select the correct answer.
Melinda conducted an experiment regarding the effectiveness of two graphic design training courses, Image-nation and Perfect Pics. She randomly selected 20 people from her marketing team and assigned 10 team members to each training course.
To determine the effectiveness of Image-nation and Perfect Pics, Melinda assigned the same task to all participants at the beginning and at the end of each program. She stated that a training course is effective if there is a decrease in time required to complete a graphics task. At the beginning of each course, Melinda found the average time to complete a task for Image-nation participants to be 60 minutes and the average time to complete a task for Perfect Pics participants to be 70 minutes. At the end of each training course, Melinda found the time taken to complete a task for Image-nation participants to be 50 minutes and the average time to complete a task for Perfect Pic participants to be 55 minutes.
Which statement should be included in Melinda’s report of the experiment's results?
A.
The Image-nation and Perfect Pics courses are both effective because the average time to complete a task decreased for each program; however, Image-nation is the more effective program because it yielded a greater decrease in the average time to complete a task.
B.
Perfect Pics is the only course that resulted in a decreased average time to complete a task; therefore, Perfect Pics is the more effective course.
C.
Image-nation is the only course that resulted in a decreased average time to complete a task; therefore, Image-nation is the more effective course.
D.
The Image-nation course and the Perfect Pics course are both effective because the average time to complete a task decreased for each course; however, Perfect Pics is the more effective course because it yielded a greater decrease in the average time to complete a task
Answer: c
Step-by-step explanation:....
The statement 'The Image-nation course and the Perfect Pics course are both effective because the average time to complete a task decreased for each course; however, Perfect Pics is the more effective course because it yielded a greater decrease in the average time to complete a task' should be included in Melinda’s report of the experiment's results.
The correct answer is option (D)
What is average?"It is calculated by adding all the numbers and then dividing by total count of those numbers."
For given example,
At the beginning of each course,
the average time to complete a task for Image-nation participants to be 60 minutes
⇒ t1 = 60
the average time to complete a task for Perfect Pics participants to be 70 minutes
⇒ x1 = 70
At the end of each training course,
the average time taken to complete a task for Image-nation participants to be 50 minutes
⇒ t2 = 50 minutes
the average time to complete a task for Perfect Pic participants to be 55 minutes.
⇒ x2 = 55 minutes
The decrease in average time to complete a task for Image-nation is,
t1 - t2
= 60 - 50
= 10
And the decrease in average time to complete a task for Perfect Pics is
x1 - x2
= 70 - 55
= 15
This means, Perfect Pics is the more effective course because it yielded a greater decrease in the average time to complete a task.
Therefore, the statement 'The Image-nation course and the Perfect Pics course are both effective because the average time to complete a task decreased for each course; however, Perfect Pics is the more effective course because it yielded a greater decrease in the average time to complete a task' should be included in Melinda’s report of the experiment's results.

O 16
O 30
O 44
O 14
Answer:
30
Step-by-step explanation:
pretty sure you just add 22 and 8
The correct option is option B.
It is given that length of segment AB is 22 and BC is 8.
We have to find length of segment AC by using segment addition postulate .
What is the segment addition postulate ?
Segment addition postulate states that a line segment divided into smaller pieces is the sum of the lengths of all those smaller segments.
As per the question ;
Length of segment AB = 22
Length of segment BC = 8
So ;
Using the segment addition postulate we get ;
Length of segment AC = Length of segment AB + Length of segment BC
or
Length of segment AC = 22 + 8
or
Length of segment AC = 30
Thus , the correct option is option B i.e., Length of segment AC will be 30.
