Using linear function concepts, it is found that the industry’s percent change from 2008 to 2018 will be of:
b. -27%
What is a linear function?A linear function is modeled by:
[tex]y = mx + b[/tex]
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0.In this problem:
The industry had 63.1 thousand jobs in 2008, hence b = 63.1.This number is expected to decline at an average annual rate of 1.7 thousand jobs per year from 2008 to 2018, hence m = -1.7.Thus, the function is:
y = -1.7x + 63.1.
In 2018, which is 10 years after 2008, the value of the function is:
y(10) = -1.7(10) + 63.1 = 46.1.
The percent change is given by the change divided by the initial value, hence:
(46.1 - 63.1)/63.1 = -27%
Hence option b is correct.

The correct answer is b. -27%.
To solve this problem, we need to find the number of jobs in 2018 and then calculate the percent change from 2008 to 2018.
Given information:
- Number of jobs in 2008: 63.1 thousand
- Average annual rate of decline: 1.7 thousand jobs per year
- Time period: 2008 to 2018 (10 years)
Step 1: Find the total decline in jobs from 2008 to 2018.
Total decline in jobs = Average annual rate of decline × Number of years
Total decline in jobs = 1.7 thousand × 10 years = 17 thousand jobs
Step 2: Find the number of jobs in 2018.
Number of jobs in 2018 = Number of jobs in 2008 - Total decline in jobs
Number of jobs in 2018 = 63.1 thousand - 17 thousand = 46.1 thousand jobs
Step 3: Calculate the percent change from 2008 to 2018.
Percent change = (Change in value / Original value) × 100%
Percent change = ((46.1 - 63.1) / 63.1) × 100%
Percent change = (-17 / 63.1) × 100%
Percent change ≈ -27%
Therefore, the industry's percent change from 2008 to 2018 is approximately -27%.
Number of jobs in 2018 = [tex]46.1\text{ thousand} \\[/tex]
Percent change from 2008 to 2018 = [tex]-27\%[/tex]

In 2008, there were 6.7 × 109 people living on earth. What is that number in standard notation?
A.) 6,700,000
B.)6,700,000,000
C.)67,000,000
D.)67,000,000,000
Answer:
B) 6,700,000,000 people.
Step-by-step explanation:
We have been given that in 2008, there were [tex]6.7\times 10^9[/tex] people living on earth. We are asked to convert our given population in standard notation.
While changing scientific notation to standard notation we just move the decimal as many times as the exponent indicates. We can see that our exponent is 9, so we will move the decimal to 9 places right.
[tex]6.7\times 10^9=6.7\times 1000000000[/tex]
[tex]6.7\times 10^9=6700000000[/tex]
Therefore, there were 6,700,000,000 people living on earth and option B is the correct choice.
Answer:
B.)6,700,000,000
Step-by-step explanation:
SO when you have to transform from the scientific notation into standar notation, you just have to move the decimal point to the right the number of positions that the scientific notation has as the exponent, in this case it is 9, so you move one position the decimal point to the right to make the number 67, and then add 8 zero´s to the right:
6,700,000,000
As you can see you moved the decimal point 9 positions to the right.
So that´s how you can convert scientific notation to standard notation.

Which lines are Parallel? Justify your answer
Answer:
Lines e and f are parallel since their alternate exterior angles 75 ad 75 are congruent.
Step-by-step explanation:
Parallel lines mean that angle relationships exits where specific angles are congruent to each other. 75 and 75 are in the position of alternate exterior angles for lines e and f. Since they are congruent, these lines must be parallel. However, a and b have same side exterior angles which must add to 180. 75 + 115 does not equal 180. It equals 190. Therefore a and b cannot be parallel.

A triangle is dilated by a scale factor of n = 1/3 . Which statement is true regarding the dilation?
It is a reduction because n > 1.
It is a reduction because 0 < n < 1.
It is an enlargement because n > 1.
It is an enlargement because 0 > n > 1
Answer: The second statement is true. It is a reduction because 0 < n < 1.
Step-by-step explanation:
Given: A triangle is dilated by a scale factor of n = 1/3 .
as n is less than 1 but greater than 0.
A dilation is a rigid transformation that forms an image that is the same shape as of the original figure, but with a different size. A dilation transform a figure by scalar factor 'n' about the center of dilation is a fixed point in the plane which never change.
A dilation that forms a larger image is known as enlargement. A dilation that forms a smaller image is known as reduction.
• If n is greater than 1, then the image is an enlargement.
• If n is between 0 and 1, then the image is a reduction .
• If n is 1, the figure and then the image are exactly same.

the equation of a curve is xy=12 and the equation of a line l is 2x+y=k where k is a constant .In the case where k=11 find the coordinates of the points of intersection of l and the curve.
The coordinates of the points of intersections of [tex]l[/tex] and the curve are [tex](x_{1}, y_{1}) = (4,3)[/tex] and [tex](x_{2}, y_{2}) = (1.5, 8)[/tex].
According to the statement, we get the following nonlinear system of equations:
[tex]x\cdot y = 12[/tex] (1)
[tex]2\cdot x + y = 11[/tex] (2)
Now we proceed to solve for each variable by algebraic means. By (1):
[tex]y = \frac{12}{x}[/tex]
Then we apply the formula in (2):
[tex]2\cdot x + \frac{12}{x} = 11[/tex]
[tex]2\cdot x^{2}+12 = 11\cdot x[/tex]
[tex]2\cdot x^{2}-11\cdot x +12 = 0[/tex]
Roots are found by the quadratic formula and (1):
[tex]x_{1} = 4[/tex], [tex]y_{1} = 3[/tex]
[tex]x_{2} = 1.5[/tex], [tex]y_{2} = 8[/tex]
The coordinates of the points of intersections of [tex]l[/tex] and the curve are [tex](x_{1}, y_{1}) = (4,3)[/tex] and [tex](x_{2}, y_{2}) = (1.5, 8)[/tex].

Explain why the functions with the given graphs can't be solutions of the differential equation dy dt = et(y − 1)2.
Please see attached document for the graphs:
The functions with the given graphs can't be solutions of
the differential equation dy dt = et(y − 1)2.
(a) won’t work, since it has negative slope on portions of its solutions. The
slope, e t (y − 1)2 , is a nonnegative function.
(b) won’t work, since it has positive slope at y = 1, where the slope must be flat.
Functions with given graphs cannot be solutions to the differential equation dy / dt = e^t(y-1)^2 because their graphs don't satisfy the conditions imposed by the equation, such as non-oscillatory behavior and non-linear variation with time.
Explanation:The question pertains to why certain functions represented by their graphs cannot be solutions to the differential equation dy / dt = et(y-1)2. The explanation lies in the structure of the given differential equation and the properties of function graphs.
Equation dy / dt = et(y-1)2 is a non-linear first order differential equation. To be a solution to this equation, a function's graph must satisfy certain conditions imposed by the equation. However, if certain function graphs represent an undefined curve or if their graphs demonstrate oscillatory behavior, they do not satisfy these criteria.
For instance, the differential equation demands non-oscillatory behavior as seen in the general solution provided in the reference: Yn(x) = Ce-Bx +De+Bx. This form describes a gradual attenuation of y(x), i.e., it does not oscillate. Similarly, if a graph represents a function that varies non-linearly with time (like In[A] vs. Time), it does not represent a solution to the differential equation as well.
Thus, the inability of certain function graphs to satisfy the conditions required by the given differential equation is the reason they cannot be its solutions.

A pool can be filled by one pipe in 4 hours and by a second pipe in 12 hours. How long will it take using both pipes to fill the pool?
The individual pipes can fill the pool in 4 hours and 12 hours respectively then using both pipes together, it will take 3 hours to fill the pool.
Use the concept of fraction defined as:
A fraction is a part of the whole number and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called a fraction. It can be written in the form of p: q, which is equivalent to p / q.
Give that,
One pipe can fill the pool in 4 hours.
Another pipe can fill the pool in 12 hours.
The first pipe fills the pool in 4 hours,
So its rate is 1/4 of the pool per hour.
Similarly,
The second pipe fills the pool in 12 hours,
So its rate is 1/12 of the pool per hour.
To find the combined rate, when both pipes are used together,
Add their individual rates:
(1/4 + 1/12) = 3/12 + 1/12 of the pool per hour.
(1/4 + 1/12) = 1/3 of the pool per hour.
Now, to find the time it takes to fill the pool using both pipes,
Take the reciprocal of the combined rate,
1 / (1/3) = 3 hours.
Hence,
Using both pipes together, it will take 3 hours to fill the pool.
