Question:
Which of the following expressions represents the distance between 1.7 and −1/2 on a number line?
Choose 1 answer:
C. None of the above
Answer:
Step-by-step explanation:
Given
Numbers: 1.7 and -1/2
Required
Determine the distance
To calculate the distance, we start by calculating the difference between the given numbers;
Then, we calculate the distance;
<em>In this case, the distance is meant to be positive; So, we'll introduce the symbol for absolute value;</em>
Hence,
Substitute for Difference;
<em>Hence, the correct option is B</em>
Okay, the answer for the first problem is -24x-54. The second is -12k^4-16k^3+20k^2. Finally. the third one is -24x^3. Hope you get it.
Answer:
The required function is P(x)=-1.3x+49.
Step-by-step explanation:
Let P(x) be the percentage of residents who regularly used the news outlet x years after 2000.
It is given that in 2000, 49 % of the residents in a large city regularly used newspapers for getting news.
Initial percentage of residents who regularly used the news = 49
It has decreased at an average rate of approximately 1.3 % per year since 2000.
It is decreasing by 1.3% so,
The slope intercept form of a line is
.... (1)
where, m is slope and b is y-intercept or initial value.
Substitute y=P(x), m=-1.3 and b=49% in equation (1).
Therefore, the required function is P(x)=-1.3x+49.
