Answer:
1.2
Step-by-step explanation:
Output of f, which also means f(x), when x = -6 is 1.2.
Using the graph given, this implies that, when x = -6, the corresponding value of f(x) will give us 1.2.
Thus:
f(-6) = 1.2 =>> (-6, 1.2).
Can someone help me with this? 4:18 and 2:12 equivalent?
Answer:
They aren't equivalent
Step-by-step explanation:
Look at them as simplified fractions
4/18 = 2/9
2/12 = 1/6
If both of these are in their most simplified forms then its not equivalent!
Using the segment addition postulate, find the length of segment AC.
AB = 22
BC = 8
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.

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.

A bicycle manufacturing company makes a particular type of bike. Each child bike requires 4 hours to build and 4 hours to test. Each adult bike requires 6 hours to build and 4 hours to test. With the number of workers, the company is able to have up to 120 hours of building time and 100 hours of testing time for a week. If c represents child bikes and a represents adult bikes, can the company build 20 child bikes and 6 adult bikes in a week. (2 points)
No, because the bike order does not meet the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100
No, because the bike order does not meet the restrictions of 4c + 4a ≤ 120 and 6c + 4a ≤ 100
Yes, because the bike order meets the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100
Yes, because the bike order meets the restrictions of 4c + 4a ≤ 120 and 6c + 4a ≤ 100
Answer:
4c + 6a < = 120 ...4(20) + 6(6) = 116 <== correct
4c + 4a < = 100....4(20) + 4(6) = 104 <== incorrect

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.
The correct answer is option (D)

Farah predicts that the average text messages sent by her family will be 2042 messages each of the last 6 months in 2019. The number of text messages used during 5 of those months were 2800, 2481, 2105, 1975, 2732. How many text messages must be sent during the sixth month for her prediction to be true?
Answer:
159 text messages
Step-by-step explanation:
Given that:
Predicted average = 2042
Number of months = 6
Number of texts for each of last 5 months :
Let number of text that must be sent in the sixth month = x
Predicted Average = (sum of texts / Number of months)
2042 = (2800 + 2481 + 2105 + 1975 + 2732 + x) / 6
2042 = (12093 + x) / 6
Cross multiply :
6 * 2042 = 12093 + x
12252 = 12093 + x
x = 12252 - 12093
x = 159

A national census is mandated by the Constitution of Pakistan to be held every ten years. After the independence of Pakistan in 1947, the first census took place in 1951. Figure 1 reflects the increase in population of Pakistan during last four national census. The increase between 1972 and 2017 could be approximated by a linear function. If in 1972 the population was 65.309 million and as per the census data of 2017 the population was 207.774 million;
a) Determine the estimation function P = f (t), where P equals the population of Pakistan and t equals time measured in years since 1972.
b) Interpret the slope and P intercept
c) According to this function, what will be the estimated population of Pakistan in 2027 census?

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
Which shows 9.635 written in expanded form, using powers of ten
Step-by-step explanation:
The expanded form of 9.635 is given by :
[tex]9.635 =9+\dfrac{6}{10}+\dfrac{3}{100}+\dfrac{5}{1000}[/tex]
or
[tex]9.635 =9+0.6+0.03+0.005[/tex]
We can write it using the powers of ten.
[tex]9.635 =9.635 \times 10^0[/tex]
10⁰ is equal to 1.
Hence, this is the required solution.
